System and method for increasing recognition accuracy and modifying the behavior of a device in response to the detection of different levels of speech

摘要

The present invention discloses a system and method for controlling the response of a device after a whisper, shout, or conversational speech has been detected. In the preferred embodiment, the system of the present invention modifies its speech recognition module to detect a whisper, shout, or conversational speech (which have different characteristics) and switches the recognition algorithm model, and its speech and dialog output. For example upon detection a whisper, the device may change the dialog output to a quieter, whispered voice. When the device detects a shout it may talk back with higher volume. The device may also utilize more visual displays in response to different levels of speech.
