I have PocketSphinx installed on a small SBC running Ubuntu 18.04. I have also installed PocketSphinx-Python and I have been able to run some example python code I found including one that allows me to use microphone input.
However, I would like to write my own Python programs to access pocketsphinx, but I don't know where to find the methods used by pocketsphinx-python or how to use them.
For example there is a method called "decode"
In the example program they are using decode.end_uut()
I have no idea what this does other than it seems to print out a lot of information to the terminal and decode anything I say into the microphone. I might add that pocketsphinx has been decoding my speech at a very good accuracy so far.
However, I would like to gain more control over how my Python program interacts with pocketsphinx.
My Python IDE has intellisene and when I type in decoder. it offers up a very long list of options that can be chosen.
Where can I find information on what all these options do?
Is there any documentaion for the methods I can use via PocketSphinx-Python?
I'm building a Linguistic AI system and I 'm using pocketsphinx as the speech recognizer for the input. So I'd like to get the results of the decoding process into variable as eifficiently as possible. All I need to know is what was said into the microphone.
Thank you.

Other people have pointed me to vosk as well. The problem is that I haven't been able to find much information about vosk. I don't even know what it is, or how to use it?
Does vosk use pocketsphinx?
If not, what exactly is vosk? And where do I find detailed information on it beyond that github page, especially in terms of tutorials.?
I'm already having close to 100% accuracy with Pocket Sphinx. It's been decoding everything I throw at it with near perfection. Perhaps it likes the way I speek?
Also, if I move over to vosk It also appears to be dependent on Kaldi?
What's Kaldi?
I need total indepence from Internet. Is Vosk and Kaldi Internet independent?
Do they have dictionaries that I can modify like PocketSphinx has?
And will my original question even be answered? Will I be able to find detailed information on the methods I can use in Python when using vosk-Kaldi?
I don't want to have to install a whole new system only to discover that I'll have the same questions about how to access it efficiently from Python.
Is CMUSphinx dead?
If so why isn't this CMUSphinx group proclaimed to be obsolete or dead, and we aren't all just being pointed over to vosk-Kaldi?
This is supposed to be a CMUSphinx forum. Is CMUSphinx gargage now?

It is a software library to recognize speech just like pocketsphinx.
I'm already having close to 100% accuracy with Pocket Sphinx. It's been decoding everything I throw at it with near perfection. Perhaps it likes the way I speek?
If it is perfect already, what are you asking about then?
Also, if I move over to vosk It also appears to be dependent on Kaldi? What's Kaldi?
Kaldi is speech recognition toolkit.
I need total indepence from Internet. Is Vosk and Kaldi Internet independent?
Yes, you do not need internet.
Do they have dictionaries that I can modify like PocketSphinx has?
Yes
And will my original question even be answered? Will I be able to find detailed information on the methods I can use in Python when using vosk-Kaldi?
Sure, it is all in the sources and demos.
I don't want to have to install a whole new system only to discover that I'll have the same questions about how to access it efficiently from Python.
Ok, it is up to you.
Is CMUSphinx dead?
Yes.
If so why isn't this CMUSphinx group proclaimed to be obsolete or dead, and we aren't all just being pointed over to vosk-Kaldi?
You are pointed over to vosk-kaldi.

"If it is perfect already, what are you asking about then?"
I was asking for information on how to access and control pocketsphinx from Python. I wasn't complaining that it doesn't decode speech well.
And I have a feeling that if I move over to vosk-kaldi I'll end up having the same questions. And I will have basically gained nothing.
But hey, I'll give it a shot.
The thing that is so disusting is that I have already spend about 2 weeks learning all about pocketsphinx. Now I'll need to start all over from scratch learning about vosk-kaldi.
And I've already done searchers for tutorials on vosk and kaldi and I haven't found much. Do they have a tutorial page like CMUSphinx has? At leat CMUSphinx provided quite a bit of documentation. https://cmusphinx.github.io/wiki/tutorial/
This feels like going back to square one moving over to vosk-kaldi. I hope it's worth it.

Defaulting to user installation because normal site-packages is not writeable
ERROR: Could not find a version that satisfies the requirement vosk (from versions: none)

(so then I tried the following:
james@james-desktop:~/vosk-kaldi$ python3 -m pip install vosk
Defaulting to user installation because normal site-packages is not writeable
ERROR: Could not find a version that satisfies the requirement vosk (from versions: none)
ERROR: No matching distribution found for vosk
(Same error)
Just for the record I was able to install pocketbase, pocketsphinx , and pocketsphinx-python on this machine with no problems. And it's all working.

What exactly is vosk, and why is it needed? Isn't Kaldi suppoosed to be the SRE?
If you want to simply use speech recognizer from python, you can use vosk prepackaged wheels and models. Kaldi is more a system for speech researchers with complex install, api and usage.

Is there anyone still alive who can answer questions about Pocket Sphinx.? I'd rather be using pocketsphinx to be honest. It was looking really promising for my specific project.
In terms of not being able to find any help, I'm finding that vosk isn't any better. I can't find any information on vosk at all beyond the github page which has very limited information.

Although I'm probably going to have as many questions about vosk as I have for pocketsphinx.
The first thing I'll want to do is empty its dictionary and start my own dictionary from scratch. I already know how to do that for pocketsphinx.
Currently I have pocketsphinx running. And it's decoding my speech close to 100% accuracy. In fact, most of the time it is 100% accurate. As I say, it must like my voice.
The things I need to know are little things, like how to stop it from printing out all the INFO: and debug statements on the command line. It basically prints out several pages of what it's doing with the decided speech somewhere in the middle. I'd like to be able to turn off those printouts. It's nice to have them when needed, but I don't need them when everything is working properly.
Here's my Python Code for Pocket Sphinx:
# This program is working!# Needed to set the microphone input correctly on the desktop mic app.# Saturday April 18th.importsubprocessascmdLinefromosimportenviron,pathimportpyaudiofrompocketsphinx.pocketsphinximport*fromsphinxbase.sphinxbaseimport*cmdLine.call('clear')MODELDIR="pocketsphinx/model"config=Decoder.default_config()config.set_string('-hmm',path.join(MODELDIR,'en-us/en-us'))config.set_string('-lm',path.join(MODELDIR,'en-us/en-us.lm.bin'))config.set_string('-dict',path.join(MODELDIR,'en-us/cmudict-en-us.dict'))decoder=Decoder(config)p=pyaudio.PyAudio()stream=p.open(format=pyaudio.paInt16,channels=1,rate=16000,input=True,frames_per_buffer=1024)stream.start_stream()in_speech_bf=Falsedecoder.start_utt()Result=""whileTrue:buf=stream.read(1024)ifbuf:decoder.process_raw(buf,False,False)ifdecoder.get_in_speech()!=in_speech_bf:in_speech_bf=decoder.get_in_speech()ifnotin_speech_bf:decoder.end_utt()Result=decoder.hyp().hypstrprint(Result)breakelse:breakprint("Decoded Speech: {0}".format(Result))
And all I want it to do is print out the final decoded speech.

Notice near the bottom it prints:

Decoded Speech: hello my name is james
That's 100% perfectly decoded speech.
And it printed both those lines because my program printed those lines.
How do I shut off all the other messages?
I'd really like to find documentation on the Pocket Sphinx source code so I can see what the methods I call actualy do, and what parameters I can send them to do things like telling them not to print messages.
I have pocketsphinx running. I like it. I just want to have more control over it from Python, that's all. Simple little things like telling it to quit printing debug message.

All the ALSA lib comments are coming from Pyaudio. So I'll, need to look into how I can turn those off.
But then vosk prints a bunch of comments before starting to capture speech. It doesn't actually start capturing speech until I've printed out "STARTING HERE"
Then I'm getting information from every word it detects along with the "text": where it finally gives me what was actually said in quotes.
Do I then need to dig that result out of there to put it into a string I can actualy use?
Isn't there a way to just get the final result and move on to working with that?
I'm, basically right back to where I was with Pocket Spinkx. I mean, I could make this work, but it's kind of ugly. Surely there are cleaner ways to work with this? I just want an SRE that's goign to report what was said without printing out a bunch of unnecessary comments to the terminal.
Is there any documented source code for Vosk?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Thanks for the information on alsa config, and json too.
Sorry to hear that there's no documentation for vosk.
How's a person supposed to learn it? Just keep coming here and asking questions?
I just want to iron out a few things so I can use an SRE for my Linquistic AI project.
I like Pocket Sphinx because I understand how to modify its dictionary.
I have no clue how to modify the dictionary vosk uses.
My Linguistic AI projects is all about building a dictionary from the ground up. So I really need to start with an empty dictionary. Something I can then have my AI software build from the ground up as it learns new words.
vosk does look like a better SRE, but I need it to be as flexible as Pocket Sphinx was in terms of building the dictionary.
So little information, and no tutorials. That's a bummer! I'd think there should be some good tutorials around on how to use and modify vosk.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
How's a person supposed to learn it? Just keep coming here and asking questions?
Yes. Many people can read code too, it is the best documentation.
So little information, and no tutorials. That's a bummer! I'd think there should be some good tutorials around on how to use and modify vosk.
Eventually there will be some tutorials but for now the speed of the development of the technology makes it very hard to create extensive documentation. You can check also
It can be difficult to get a simple answer to a question.
I've got vosk installed and running on a computer. Vosk only. Not Kaldi. Although Vosk apparently comes with some form of a Kaldirecognitzer.
My question is where do I find the vocabulary dictionary, and how do I modfied it?
And is it easy to do?
With pocketsphinx it is extremely easy to modify the dictionary or even created a new dictionary from scratch. And that was the main attraction to pocketsphinx. I need to be able to create a dictionary from scratch and be able to modify it and add to it on the fly easily and programmatically. This is extremely easy to do with pocketsphinx.
Currently with vosk I have no idea where to even find the vocabulary dictionary much less how to modify it or swap it out. In my Linguistic AI project I need the ability to create several different dictionaries for special cases and be able to swap between them programmatically on the fly.
As I say, this is very easy to do with pocketsphinx. But I have no clue how to do this with vosk.
Where can I find information on how to create specialized dictionaries for vosk, and how difficult is it to do?
I'm thinking this may be the deciding factor of whether I use vosk or pocketsphinx for my project. If it's not easy to work with the vosk vocabulary dictionary, then it's not going to be of much use in my project. So the answer to this question is paramount for my application.
And a simple answer like "Yes it can be easily done" is not a useful answer. A useful answer is to point to information on exactly how to do it.
Without knowing how to do it knowing that it's supposedly easy to do isn't very helpful.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Thanks for all the information Nickolay. You've been very helpful. Vosk does seem to be a very good SRE, but the dictionary modifications appears to be too complex for my purpose. So I'm going to need to go back to using pocketsphinx just for the ease-of-use of its dictionary.
In any case, thanks for your patience and time. You've been very helpful.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I have PocketSphinx installed on a small SBC running Ubuntu 18.04. I have also installed PocketSphinx-Python and I have been able to run some example python code I found including one that allows me to use microphone input.
However, I would like to write my own Python programs to access pocketsphinx, but I don't know where to find the methods used by pocketsphinx-python or how to use them.
For example there is a method called "decode"
In the example program they are using decode.end_uut()
I have no idea what this does other than it seems to print out a lot of information to the terminal and decode anything I say into the microphone. I might add that pocketsphinx has been decoding my speech at a very good accuracy so far.
However, I would like to gain more control over how my Python program interacts with pocketsphinx.
My Python IDE has intellisene and when I type in decoder. it offers up a very long list of options that can be chosen.
Where can I find information on what all these options do?
Is there any documentaion for the methods I can use via PocketSphinx-Python?
I'm building a Linguistic AI system and I 'm using pocketsphinx as the speech recognizer for the input. So I'd like to get the results of the decoding process into variable as eifficiently as possible. All I need to know is what was said into the microphone.
Thank you.
Try https://github.com/alphacep/vosk-api, it is much more accurate.
Other people have pointed me to vosk as well. The problem is that I haven't been able to find much information about vosk. I don't even know what it is, or how to use it?
Does vosk use pocketsphinx?
If not, what exactly is vosk? And where do I find detailed information on it beyond that github page, especially in terms of tutorials.?
I'm already having close to 100% accuracy with Pocket Sphinx. It's been decoding everything I throw at it with near perfection. Perhaps it likes the way I speek?
Also, if I move over to vosk It also appears to be dependent on Kaldi?
What's Kaldi?
I need total indepence from Internet. Is Vosk and Kaldi Internet independent?
Do they have dictionaries that I can modify like PocketSphinx has?
And will my original question even be answered? Will I be able to find detailed information on the methods I can use in Python when using vosk-Kaldi?
I don't want to have to install a whole new system only to discover that I'll have the same questions about how to access it efficiently from Python.
Is CMUSphinx dead?
If so why isn't this CMUSphinx group proclaimed to be obsolete or dead, and we aren't all just being pointed over to vosk-Kaldi?
This is supposed to be a CMUSphinx forum. Is CMUSphinx gargage now?
You are welcome to ask,
No
It is a software library to recognize speech just like pocketsphinx.
If it is perfect already, what are you asking about then?
Kaldi is speech recognition toolkit.
Yes, you do not need internet.
Yes
Sure, it is all in the sources and demos.
Ok, it is up to you.
Yes.
You are pointed over to vosk-kaldi.
"If it is perfect already, what are you asking about then?"
I was asking for information on how to access and control pocketsphinx from Python. I wasn't complaining that it doesn't decode speech well.
And I have a feeling that if I move over to vosk-kaldi I'll end up having the same questions. And I will have basically gained nothing.
But hey, I'll give it a shot.
The thing that is so disusting is that I have already spend about 2 weeks learning all about pocketsphinx. Now I'll need to start all over from scratch learning about vosk-kaldi.
And I've already done searchers for tutorials on vosk and kaldi and I haven't found much. Do they have a tutorial page like CMUSphinx has? At leat CMUSphinx provided quite a bit of documentation. https://cmusphinx.github.io/wiki/tutorial/
This feels like going back to square one moving over to vosk-kaldi. I hope it's worth it.
Absolutely! Let me know if you have further questions.
Ok, I have a problem right off the bat:
I'm running Ubuntu 18.04 on a Jetson Nano arm64.
From the GitHub page I tried the foillowing:
james@james-desktop:~/vosk-kaldi$ pip3 --version
pip 20.0.2 from /home/james/.local/lib/python3.6/site-packages/pip (python 3.6)
(I have the correct verion of pip)
james@james-desktop:~/vosk-kaldi$ pip3 install vosk
Defaulting to user installation because normal site-packages is not writeable
ERROR: Could not find a version that satisfies the requirement vosk (from versions: none)
ERROR: No matching distribution found for vosk
(so then I tried the following:
james@james-desktop:~/vosk-kaldi$ python3 -m pip install vosk
Defaulting to user installation because normal site-packages is not writeable
ERROR: Could not find a version that satisfies the requirement vosk (from versions: none)
ERROR: No matching distribution found for vosk
(Same error)
Just for the record I was able to install pocketbase, pocketsphinx , and pocketsphinx-python on this machine with no problems. And it's all working.
Try
Ok, that seemed to work.
james@james-desktop:~/vosk-kaldi$ pip3 install https://github.com/alphacep/vosk-api/releases/download/0.3.3/vosk-0.3.3-cp36-cp36m-linux_aarch64.whl

I have another question. I found this page: http://kaldi-asr.org/doc/index.html
That appears to have a lot of information on it about Kaldi. But there's no mention of vosk anywhere.
What exactly is vosk, and why is it needed? Isn't Kaldi suppoosed to be the SRE?
If you want to simply use speech recognizer from python, you can use vosk prepackaged wheels and models. Kaldi is more a system for speech researchers with complex install, api and usage.
I'm not getting anywhere with vosk.
I've installed vosk and Kaldi.
I'm trying to run the following python text code for vosk
And I get the following erros:
Is there anyone still alive who can answer questions about Pocket Sphinx.? I'd rather be using pocketsphinx to be honest. It was looking really promising for my specific project.
In terms of not being able to find any help, I'm finding that vosk isn't any better. I can't find any information on vosk at all beyond the github page which has very limited information.
You need to install libfortran.so.3 with
sudo apt-get install libgfortran3You are welcome to ask.
I did install libgfortran as a dependency Kaldi.
I'll install libgfortran3 and see if that helps.
Although I'm probably going to have as many questions about vosk as I have for pocketsphinx.
The first thing I'll want to do is empty its dictionary and start my own dictionary from scratch. I already know how to do that for pocketsphinx.
Currently I have pocketsphinx running. And it's decoding my speech close to 100% accuracy. In fact, most of the time it is 100% accurate. As I say, it must like my voice.
The things I need to know are little things, like how to stop it from printing out all the INFO: and debug statements on the command line. It basically prints out several pages of what it's doing with the decided speech somewhere in the middle. I'd like to be able to turn off those printouts. It's nice to have them when needed, but I don't need them when everything is working properly.
Here's my Python Code for Pocket Sphinx:
And all I want it to do is print out the final decoded speech.
But it prints out all of the following:

Notice near the bottom it prints:
hello my name is james
Decoded Speech: hello my name is james
That's 100% perfectly decoded speech.
And it printed both those lines because my program printed those lines.
How do I shut off all the other messages?
I'd really like to find documentation on the Pocket Sphinx source code so I can see what the methods I call actualy do, and what parameters I can send them to do things like telling them not to print messages.
I have pocketsphinx running. I like it. I just want to have more control over it from Python, that's all. Simple little things like telling it to quit printing debug message.
add
config.set_string('-logfn', '/dev/null'))see also
https://stackoverflow.com/questions/17825820/how-do-i-turn-off-e-info-in-pocketsphinx
There is C documentation here. https://cmusphinx.github.io/doc/pocketsphinx/files.html. There is no Python documentation, just the source code.
Ok!
Ok I finally got VOSK running, but as I suspected I have simlar questions with vosk:
Here's my Python code:

james@james-desktop:~/vosk-kaldi/kaldi$
All the ALSA lib comments are coming from Pyaudio. So I'll, need to look into how I can turn those off.
But then vosk prints a bunch of comments before starting to capture speech. It doesn't actually start capturing speech until I've printed out "STARTING HERE"
Then I'm getting information from every word it detects along with the "text": where it finally gives me what was actually said in quotes.
Do I then need to dig that result out of there to put it into a string I can actualy use?
Isn't there a way to just get the final result and move on to working with that?
I'm, basically right back to where I was with Pocket Spinkx. I mean, I could make this work, but it's kind of ugly. Surely there are cleaner ways to work with this? I just want an SRE that's goign to report what was said without printing out a bunch of unnecessary comments to the terminal.
Is there any documented source code for Vosk?
You need to cleanup the alsa config, see https://stackoverflow.com/questions/7088672/pyaudio-working-but-spits-out-error-messages-each-time
It is json, you can parse it with
json.loads:import json
result = json.loads(rec.Result())
text = result['text']
No
"There is C documentation here. https://cmusphinx.github.io/doc/pocketsphinx/files.html. There is no Python documentation, just the source code."
This will be very helpful. Thank you!
Thanks for the information on alsa config, and json too.
Sorry to hear that there's no documentation for vosk.
How's a person supposed to learn it? Just keep coming here and asking questions?
I just want to iron out a few things so I can use an SRE for my Linquistic AI project.
I like Pocket Sphinx because I understand how to modify its dictionary.
I have no clue how to modify the dictionary vosk uses.
My Linguistic AI projects is all about building a dictionary from the ground up. So I really need to start with an empty dictionary. Something I can then have my AI software build from the ground up as it learns new words.
vosk does look like a better SRE, but I need it to be as flexible as Pocket Sphinx was in terms of building the dictionary.
So little information, and no tutorials. That's a bummer! I'd think there should be some good tutorials around on how to use and modify vosk.
Yes. Many people can read code too, it is the best documentation.
Eventually there will be some tutorials but for now the speed of the development of the technology makes it very hard to create extensive documentation. You can check also

It can be difficult to get a simple answer to a question.
I've got vosk installed and running on a computer. Vosk only. Not Kaldi. Although Vosk apparently comes with some form of a Kaldirecognitzer.
My question is where do I find the vocabulary dictionary, and how do I modfied it?
And is it easy to do?
With pocketsphinx it is extremely easy to modify the dictionary or even created a new dictionary from scratch. And that was the main attraction to pocketsphinx. I need to be able to create a dictionary from scratch and be able to modify it and add to it on the fly easily and programmatically. This is extremely easy to do with pocketsphinx.
Currently with vosk I have no idea where to even find the vocabulary dictionary much less how to modify it or swap it out. In my Linguistic AI project I need the ability to create several different dictionaries for special cases and be able to swap between them programmatically on the fly.
As I say, this is very easy to do with pocketsphinx. But I have no clue how to do this with vosk.
Where can I find information on how to create specialized dictionaries for vosk, and how difficult is it to do?
I'm thinking this may be the deciding factor of whether I use vosk or pocketsphinx for my project. If it's not easy to work with the vosk vocabulary dictionary, then it's not going to be of much use in my project. So the answer to this question is paramount for my application.
And a simple answer like "Yes it can be easily done" is not a useful answer. A useful answer is to point to information on exactly how to do it.
Without knowing how to do it knowing that it's supposedly easy to do isn't very helpful.
It is not very easy but somewhat doable, you can check for details http://vpanayotov.blogspot.com/2012/06/kaldi-decoding-graph-construction.html
Thanks for all the information Nickolay. You've been very helpful. Vosk does seem to be a very good SRE, but the dictionary modifications appears to be too complex for my purpose. So I'm going to need to go back to using pocketsphinx just for the ease-of-use of its dictionary.
In any case, thanks for your patience and time. You've been very helpful.
