ABSTRACT:
A method improves voice recognition by improving storage of voice recognition (VR) templates. The improved storage means that more VR models can be stored in memory. The more VR models that are stored in memory, the more robust the VR system, and therefore the more accurate the VR system. Lossy compression techniques are used to compress VR models. In one embodiment, Mu-law compression and A-law expansion are used to compress and expand VR models. In another embodiment, Mu-law compression and Mu-law expansion are used to compress and expand VR models. VR models are compressed during a training process, and they are expanded during voice recognition.
