Voice control system and its wake-up method, wake-up device and appliances, coprocessor

摘要

The present invention relates to a voice control system and its wake-up method, a wake-up device and a home appliance, and a coprocessor. The wake-up method includes: a collecting step of collecting voice information; Processing the voice information to determine whether voice information includes a voice of a person, separating voice information segments that include voice of a person when the voice includes a voice, and entering a recognition phase; Recognizing a wakeup word from a voice information segment including a voice of a person, entering a wakeup step when a wakeup word is recognized, and returning to a collection step if the wakeup word is not recognized; And a wake-up step of waking up the speech recognition processor. Each member is modularly designed in the above manner. The speech recognition processor only works when speech recognition is required, and it reduces energy consumption by avoiding constant all-weather operation. The voice wakeup device recognizes only the wakeup word, low power consumption, and consumes little energy even if it operates all the weather, and the power consumption of conventional speech recognition is relatively large.
