Voice control system, wakeup method thereof, wakeup device, home appliance, coprocessor

摘要

The present invention relates to a voice control system, a wakeup method thereof, a wakeup device, a home appliance, and a coprocessor. The wake-up method includes a collection step of collecting voice information, processing the voice information to determine whether the voice information includes a human voice, and if so, a voice information segment including the human voice. A wake-up word is recognized for a processing step that separates and moves to a recognition step, and a speech information segment including a human voice, and if a wake-up word is recognized, the flow moves to a wake-up step and A recognition step that returns to the collecting step and a wakeup step that wakes up the speech recognition processor if an upward is not recognized. Each part is modularized by this method. The speech recognition processor operates only when speech recognition is required, avoids all-weather continuous operation, and reduces energy consumption. Since the voice wakeup device recognizes only the wakeup word, the power consumption is low. Even with all-weather continuous operation, energy consumption is very low, which can solve the problem of high power consumption of conventional speech recognition.
