Wakeup method, wakeup device and wakeup equipment for vehicle-mounted voice system as well as readable medium

Abstract

The description discloses a wakeup method, a wakeup device and wakeup equipment for a vehicle-mounted voice system as well as a readable medium. The method comprises the following steps: continuouslydividing acquired audio data into multiple audio frames, wherein each audio frame contains voice data with certain duration; inputting a preset number of audio frames consecutive every two into an acoustic feature extraction module for extracting acoustic eigenvectors; inputting the acoustic eigenvectors into a deep neural network to obtain a probability value corresponding to a preset wakeup word; waking up the vehicle-mounted voice system when the probability value corresponding to the preset wakeup word is judged to be greater than a preset first threshold value; inputting the processed audio data into the deep neural network to obtain the probability value corresponding to the preset wakeup word. The vehicle-mounted voice system can be waken up more accurately after the size relationship between the probability value corresponding to the preset wakeup word and the first threshold is compared.

Description

technical field [0001] This specification relates to a voice system, in particular to a wake-up method, device, readable medium and equipment for a vehicle voice system. Background technique [0002] The vehicle-mounted voice system is a new type of in-vehicle human-computer interaction system, which realizes the application of intelligent voice technology in the vehicle scene. The driver can operate the hardware devices and software systems in the car by speaking, and realize a series of human-computer interaction functions such as playing music, Bluetooth calls, and turning on navigation. [0003] When the existing vehicle-mounted voice system needs to be woken up, the input audio data is directly recognized, and when the pre-stored wake-up word is recognized in the audio data, the vehicle-mounted voice system is woken up. [0004] During the wake-up recognition of the above-mentioned vehicle-mounted voice system, the wake-up words in the audio data are recognized, and th...

AI Technical Summary

Problems solved by technology

[0004] When the above-mentioned in-vehicle voice system wakes up and recognizes, it is the recognition of the wake-up word in the audio data, which cannot accurately wake up the in-vehicle voice system.
