Voxforge Spanish Model Released

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.
