Abstract
Embodiments of the present disclosure disclose a voice activation method, an apparatus, an electronic device, and a storage medium thereof. The voice activation method includes: capturing a voice signal in a vehicle; calculating an acoustic score of an activation keyword extracted from the voice signal, the acoustic score being used for indicating authenticity of the activation keyword, the authenticity of the activation keyword being a probability that the activation keyword is used for waking up the electronic device to perform a voice activation operation, and a magnitude of the acoustic score being positively correlated to a magnitude of the probability; determining a voice activation threshold according to a noise level in the vehicle, a magnitude of the voice activation threshold being negatively correlated to a magnitude of the noise; and performing the voice activation operation when the acoustic score is greater than the voice activation threshold.
