1. A method to perform speech recognition, comprising:
- communicating voice information encoded using a voice compression algorithm over a voice channel;
receiving a request for voice information for a speech recognition system;
encoding requested voice information to be communicated to said speech recognition system over a data channel using said voice compression algorithm used for said voice channel after switching from said voice channel to said data channel; and
communicating said requested voice information encoded using said voice compression algorithm over said data channel.
