VoxForge for Arduino Recognizer

Hi all,

I am one of the co-developers of MOVI (http://www.audeme.com), an offline speech recognition board that integrates with Arduino. The board internally uses PocketSphinx and we have managed to package up the Spanish and German models from VoxForge in a way that we can now also use them for the recognizer (on top of English).

FYI. I wrote two Instructables on it:

http://www.instructables.com/id/Connection-less-German-Speech-Recognition-and-Synt/ 

http://www.instructables.com/id/Connection-Less-Spanish-Speech-Recognition-and-Syn/

However, I have two major questions:

a) Why are the Spanish and the German models loading and recognizing so much more slowly than the English models (that come with Pocketsphinx). In other words: Is there any optimization that I can do?

b) Does VoxForge have any other languages available as PocketSphinx models with the corresponding Phonetisaurus dictionary? (That's ultimately what we need)

Thank you for input.

Gerald

You are using very old continuous models. You need PTM model, explained in tutorial http://cmusphinx.sourceforge.net/wiki/acousticmodeltypes
Recent PTM models are available here:
Spanish cmusphinx-es-5.2.tar.gz
German cmusphinx-ptm-voxforge-de-r20161117.tar.xz
