Abstract

A voice wake-up method is applied to the field of voice interaction, and comprises the following steps: after a voice signal is received, extracting acoustic features of the voice signal, predicting posterior probabilities of the acoustic features on acoustic modeling units, and inputting the posterior probabilities into a preset evaluation model to obtain a first evaluation value, and inputting the posterior probability into a trained convolutional neural network model to obtain a second evaluation value, and judging whether to wake up or not according to the first evaluation value and the second evaluation value. The invention further discloses a voice wake-up device, electronic equipment and a storage medium. Whether wake-up words are contained in voice signals or not is judged by combining a two-stage wake-up mechanism, the influence on a result by only adopting a single model is prevented, and the wake-up rate is increased and the false wake-up rate is reduced under the conditionof ensuring low power consumption.

Description

technical field [0001] The invention relates to the technical field of voice recognition, in particular to a voice wake-up method, device, electronic equipment and storage medium. Background technique [0002] With the rapid development of intelligent interactive technology and the continuous expansion of market demand, speech recognition technology has made great progress in recent years, and has been widely used in many fields so far. Speech recognition technology is to recognize the input voice signal and convert it into text information that can be processed by the computer. Speech recognition technology can be used to realize intelligent voice interaction in many application scenarios, such as voice input, intelligent control based on voice recognition, etc. [0003] At present, in the process of waking up the device through the wake-up word using speech recognition technology, the problem of false wake-up often occurs, thereby affecting the user's experience. Conten...
