Want to add functionality to load every possible type of model

[Toine db]

I created the Windows/Windows Phone examples and I want to add/complete the innitialization part that sets the models for pocketsphinx.

Is there an overview of different Models sphinx can make and handle.
And is there a overview wich files need to be innitilized for pocketsphinx to work correctly for each type of model.
(Something more like: http://cmusphinx.sourceforge.net/wiki/tutorialam#using_the_model)

In the example I loaded a weather.dmp file just to fill in the request of -lm..... but I haven't got a clue why that was needed because the example doesn't do anything with weather.
PS: without the weather.dmp the pocketsphinx crashes

I hope someone can give me an overview so I can implement it in the examples for a next release

Yes, sure http://cmusphinx.sourceforge.net/wiki/tutorial

You could probably be more specific about this issue. If you are about pocketsphinx-wp-demo, you do not need weather.lm there in Initialize, demo should work fine without it.

Found a bug in the WP8 demo.

I was calling ps_end_utt(ps) before ever starting ps_start_utt().

Strange anough this didn't throw exception when loading a LM at innitialization!

I commited it on Nuget.
(with some other missing files for a complete working build)

Nickolay, still have the same issue and I found the line of code with the problem.

The situation is as follows (when using the WIndows Phone demo).

• I initialize PocketSphinx with only the HMM path and Dictionary file. (so no Language Model).
• I DO NOT ADD SEARCH PHRASES OR GRAMS

The code does:
1: ps_start_utt
2: ps_process_raw
3: ps_get_hyp

- here is where it goos wrong at:

hyp = ps_search_hyp(ps->search, out_best_score, NULL);

Because "search" in ps->search is NULL.
When initializing pocketsphinx with "-lm" all works fine! (then ps->search is NOT NULL)

What do I need to do to only work with a model path -hmm and a dictionary -dict.

My initialization parameters are:

  config = cmd_ln_init(NULL, ps_args(), TRUE,
        "-hmm", hmmPath,
        "-dict", dictPath,
        "-mmap", "no",
        "-logfn", logPath,
        "-kws_threshold", "1e-40",
        NULL);

Hope to hear from you.

You still need grammar or language model. For testing you are using grammar I suppose.

[Toine db]

That worked, I will commit a change to not make it possible initialization without a grammer or language model.

Can you tell me what the Config parameter option for gram/jsgf files are? (-lm crashes when using grammer files)

Is there a overview of these parameters? Becuase after looking at this post http://bit.ly/1yTUy2D I'm thinking I can tweak a litle with these parameters.
(PS the tutorial won't give much info about the cmd_ln_init options)

Hi Toine,

The option is "-jsgf".

Thanks for the info.
Gone update the Github rep for the WindowsPhone demo now.

Still have two questions for better implementation;

1: Is there any advantage in loading grams and language model in 'ps_init' compared to later on in 'ps_set_jsgf_file' or 'ps_set_lm_file'?
(other then being the default search type)

2: Is there a overview of all parameters that can be set in the config with 'cmd_ln_init' ??? (like -mmap or -lw... etc)

Thanks for the help Alexander.

You can run pocketsphinx_continuous without arguments and see the list. You can also check pocketsphinx man page.

[Toine db]

Tnx for the quick reply,
Changes for WindowsPhone demo are commited as we speak.

I will check the list!
Do you mean this by 'man page'? http://cmusphinx.sourceforge.net/wiki/tutorialpocketsphinx

[Toine db]

Dear Nickolay,

Tnx for the support, I was able to match the Config of pocketsphinx-continuos to the Windows Phone pocketsphinx.
The recognition is better, but not good anough yet.

I can see all the options that are available in pocketsphinx commandline (config) but I can't find the descriptions for that.

Are there any or where is the "Man Page" what you are talking about?
