As of today, CMUSphinx project is proud to present you the Spanish acoustic model. It was trained on the acoustic data to support both wideband recognition of microphone speech recordings and narrowband recognition of the telephone speech. Now you can build Spanish IVR using CMUSphinx tools.
You can find the model HERE.
Please try and report the accuracy results.
Also, note that there are models for many languages like German, Dutch, French or Russian. In the future we are going to expand the set of languages for your convenience.

Thanks for this. Will the location of the models for other languages mentioned (French, German etc.) be made available? Also, more details about the training data (e.g. how many hours of speech used) would be of interest.
Thanks again.

Hello Ravi!
Other models are located in the same downloads folder on sourceforge.

As for statistics, the metrics could be found on Voxforge. For spanish model it’s around 10 hours I think

Hi
I have never used sphinx before, normally I use comercial ASR.
But now after test the google ASR, i can’t guess how they do. It’s no possible to have a so big grammar. And this is what I’m looking for.
Is possible to do something similar with “sphinx” and “Voxforge Spanish Model Released”, or it has nothing to do?
thanks

Dear Assanta
It’s perfectly possible to follow Google path. You just need a passion to go through it.

Sorry, I didn’t explain very well
I wanted to ask if it’s possible to do a continuous speech recognition without grammar, with “Sphinx” and “Voxforge Model”
