US Patent 7203644 Automating tuning of speech recognition systems

Embodiments of a speech recognition system are disclosed. The system includes at least one recognizer to produce output signals from audio input signals and a feedback module to collect feedback data generated from conversion of the audio input signals to output signals. The system stores the feedback data and may also be adapted to use the feedback data as part of a training set for recognizers in the system, as part of a predictive mechanism, or both.
