PocketSphinx stops listening after I change language file. – Politepix /forums/topic/pocketsphinx-stops-listening-after-i-change-language-file/feed/ Tue, 23 Apr 2024 14:48:12 +0000 https://bbpress.org/?v=2.6.9 en-US /forums/topic/pocketsphinx-stops-listening-after-i-change-language-file/#post-1015496 <![CDATA[PocketSphinx stops listening after I change language file.]]> /forums/topic/pocketsphinx-stops-listening-after-i-change-language-file/#post-1015496 Tue, 29 Jan 2013 09:30:00 +0000 Geri Hi.
I have a pocketSphinx set up, started listening with…

[self.pocketsphinxController startListeningWithLanguageModelAtPath:self.languageModel.languageModelPath
dictionaryAtPath:self.languageModel.dictionaryPath
languageModelIsJSGF:NO];

…without any problem,
Then I suspend listening with…

[self.pocketsphinxController suspendRecognition];

Then I change the model file (it works well, as the OpenEarsEventsObserverDelegate callback method gets called) with…

[self.pocketsphinxController changeLanguageModelToFile:self.languageModel.languageModelPath
withDictionary:self.languageModel.dictionaryPath];

…and after that at a certain point I resume listening with…

[self.pocketsphinxController resumeRecognition];

…but no any recognition takes place anymore.

What am I doing wrong? Should this be working in a way like this?

Namely “Bound vocabulary” every time I generate a language model.

Is it an ARPA model or a JSGF grammar? You do need to give your models unique names.

Still really love this support, like you were sitting here around.

I have an app where I need to add words occasionally. When I generate the new files, it would go through the motions of listening, but not ever recognize anything. Based on Geri’s solution, I deleted the old dynamic dictionary and grammar files before creating the new ones and this eliminated the bug. Now I can use the same file names over and over. Hope this helps you track down the bug.

It’s a requirement that language models have unique names, not really a bug, but I’ll mention it in the docs for clarity.

Some kind of reusability considerations?

The file name that you pass to LanguageModelGenerator when you are requesting the generated model or something else?
