Tmat error about pocketsphinx.js HOT 6 CLOSED

Hi @Jsignr , could you share a little bit more details about what you did? Have model files been pre-loaded successfully? Or maybe you can share your files.

You should not need to give a -tmat argument if you set -hmm in your config.

Thanks for you reply.

I would like package model files outside the main JavaScript because I can't embedding french model acoustic (http://sourceforge.net/projects/cmusphinx/files/Acoustic%20and%20Language%20Models/French%20F0%20Broadcast%20News%20Acoustic%20Model/) into JS file (I get fatal error : CALL_AND_RETRY_2 Allocation failed - process out of memory).

So, I have generated pocketsphinx.js with
cmake -DEMSCRIPTEN=1 -DHMM_EMBED=OFF -DCMAKE_TOOLCHAIN_FILE=path_to_emscripten/cmake/Platform/Emscripten.cmake

and

python .../emscripten/tools/file_packager.py .../pocketsphinx.js/build/pocketsphinx.js --embed ..... for each file on my model folder

My simple JS :

window.onload = function() {

var recognizer = new Worker("js/recognizer.js");
recognizer.onmessage = function(event) {
console.log('Recognizer Ready');
};

var id = 0;
recognizer.postMessage('pocketsphinx.js');
recognizer.postMessage({command: 'load',
callbackId: id,
data: ["model/mdef.js",
"model/variances.js",
"model/means.js",
"model/mixture_weights.js",
"model/noisedict.js",
"model/transition_matrices.js",
]
});
recognizer.postMessage({command: 'initialize',
callbackId: id,
});
};

I was actually trying to do the same yesterday, with that model, and found that variances.js and means.js can not be loaded. I suspect these two files, who ended up very large (80+MB) are larger than some limit in the browser.

For you, what probably happens is that it went on trying to initialize the recognizer, and failed finding the files that were not loaded.

I'll dig further and update this thread if I find anything useful.

ok thanks :) I will check if it's possible to increase limit browser or other solutions.

@Jsignr so I think I got a fix:

The issue was with the array created from the binary file which requires a gigantic JavaScript line to be created, over the limit.

By adjusting the packaging script, that array can be created by concatenating smaller chunks, and finally the virtual file can be created successfully.

You can find the generated model there:
https://github.com/syl22-00/pocketsphinx.js-fr_FR-lium_french_f0

Note that you will need to set TOTAL_MEMORY to something larger. I just set it to 100MB.

And if you want to package it yourself, the modified version of file_packager.py is there:
https://github.com/syl22-00/emscripten/blob/master/tools/file_packager.py

I will then clean it up and make a full request to upstream Emscripten.

Would be great if you could update this ticket, whether you can use it successfully or not.

It works ! Thanks a lot for your help ! :-)
