Abstract

A voice awakening method and device are provided. According to an embodiment, the method includes: receiving voice information of a user; obtaining an awakening confidence level corresponding to the voice information based on the voice information; determining, on the basis of the awakening confidence level, whether the voice information is suspected wake-up voice information; and performing, in response to determining the voice information being the suspected wake-up voice information, a secondary determination on the voice information to obtain a secondary determination result, and determining whether to perform a wake-up operation on the basis of the secondary determination result. The embodiment implements a secondary verification on the voice information, thereby reducing the probability that the smart device is mistakenly awakened.
