Using PocketSphinx version 0.8 to convert a wav file to text I only get about a 50% accuracy.
Running pocketsphinx_continuous.exe on a windows machine using the pre-built language files:
-hmm model\hmm\en_US\hub4wsj_sc_8k
-lm model\lm\en_US\hub4.5000.DMP
-dict model\lm\en_US\cmu07a.dic
Which model files are best to start working on in order to get better results?
I did not see a way to attach the audio file so I just added the text.
The file is a 16khz, 16 bit, mono recording.
Here is the output result from Sphinx:
for mayor it which are to cut phone calls for this year i've got don't have back i mean what we have seen however is that armed forces present a bomb and just the big about a week ago gave an interview at rolling stone where he said that he was planning to make climate change an issue in his campaign
will see how it played out on clearly climate change does not why as the level of national priority for most americans as the economy and on employment and do you not to daughter kind of issues like i mean that's perfectly understand that wall and on the last because the parties have seen really terrific apart so far in terms of their views of climate changing climate change science that perhaps there's going to be over about discussion about what should be used to approach is to people prefer
you know is a as this horse race gets going down but it down the stretch to this year word
in a c. b. c. poll come out virtually every week rather have it and i'm asking you how many of them are men ask any of these these questions you will that's a ballot you know climate change global warming alternative energy that seems like to when you look at them calling the exit poll in what
Here is what it should be:
I mean, I wish I had a crystal ball for this year, but I don't, and a I mean what we have seen, however, is that, for instance, President Obama just think about a week ago gave an interview in Rolling Stone, where he said that he was planning to make climate change an issue in this campaign.
We'll see how it plays out. um Clearly climate change does not uh rise to the level of national priority for most Americans. As the economy and unemployment and you know other kinds of issues like that mean that perfectly understandable but nonetheless because the parties have seemingly drifted apart so far in terms of their views of climate change in climate change science that perhaps there is going to be a robust discussion about which of these 2 approaches. Do people prefer.
You know as a as this horse race gets going down the down the stretch here this year
we're gonna be see be seeing polls come out virtually every week (laughter),
but I'm asking you how many of them are gonna ask any of the these questions you asked about you know climate change global warming alternative energies. It seems like it when you look at the the polling the exit polling would.
Any insight would be appreciated.

It's actually quite accurate and catched many words. For better results more advanced features could be used like speaker detection, online per-speaker adaptation. Accuracy should improve significantly on top of that but it's some work to setup the system properly.

something wrong with the generic acoustic model ???
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Well, the beginning of the file is a telephone speech. Looking at the spectrogram it seems to be 8 khz sampled. That's why you have poor accuracy with default 16khz model.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I am confused.
When you take a 16000 Hz sampling rate file, of course it shows 8000 Hz on a spectogram.
The sampling frequency is twice the audio bandwidth.
When we say pocketsphinx need 16000 Hz it is the sampling rate, right ?
So it should be fine unless I am mistaken by something else
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
No, the file is 16khz. But the first speaker in file is a telephone speech. It has gaps from 4 to 8khz, while 16khz acoustic model expects something to be there.

You need to share an audio file
It's better to use generic english LM for generic texts
Here is the attached audio file. It is 2mb. I can also email it.
I will try the other english LM files.
With

There are no magic command line options.
Feature integration requires coding to glue several packages.
So is there anything I can do using the standard tools to improve accuracy?
For example, modify the acoustic model or dictionary?
