Voice control device and voice control method

摘要

A voice control device and a corresponding voice control method are provided. The voice control device includes a sound receiver, a sound converter, a voice identifier, and a central processing unit (CPU). The sound receiver receives a first sound signal. The sound converter converts the first sound signal from analog signal to digital signal. The voice identifier identifies a first voice signal from the first sound signal, performs a first comparison on the first voice signal and a second voice signal, and generates a wake-up signal according to the first comparison. When receiving the wake-up signal, the CPU enters a working state from a sleeping state, performs a second comparison on the first voice signal and the second voice signal, and takes over the voice input from the sound receiver and the sound converter according to the second comparison.

主权项

1. A voice control device, comprising:
a sound receiver, receiving a first sound signal; a sound converter, coupled to the sound receiver, and converting the first sound signal from analog signal to digital signal; a voice identifier, coupled to the sound converter, and identifying a first voice signal from the first sound signal, performing a first comparison on the first voice signal and a second voice signal, and generating a wake-up signal in response to the first voice signal matching the second voice signal in the first comparison; and a central processing unit (CPU), coupled to the sound converter and the voice identifier, wherein when the CPU receives the wake-up signal, the CPU enters a first working state from a first sleeping state, receives the first voice signal from the voice identifier, and performs a second comparison on the first voice signal and the second voice signal, wherein when the first voice signal matches the second voice signal in the second comparison, the CPU takes over a voice input from the sound receiver and the sound converter, and when the first voice signal does not match the second voice signal in the second comparison, the CPU re-enters the first sleeping state.
