example 1

[0061] Example 1: Using a digital signal processor (DSP, Digital Signal Processor) to eliminate audio signals at other locations. Specifically, it may include: receiving the first voice signal of the microphone in the wake-up voice position; receiving the second voice signals of the microphones in other positions; using DSP to eliminate each of the second voice signals from the first voice signal , to get the signal to be identified. For example, the DSP can subtract signals that wake up individual microphones outside of the speech location.

[0062] In an application scenario, the voice signal received by the driver's microphone includes the voice signal received by the co-pilot's microphone. If the voice signal received by the microphone of the co-pilot can be obtained, the voice signal received by the microphone of the co-pilot can be eliminated from the voice signal received by the microphone of the driver. In this way, the influence of other microphones on the signal re...

example 2

[0063] Example 2: Control the microphone at the wake-up voice position to receive sound, and prohibit the microphone at other positions to receive sound. Specifically, it may include: controlling the microphone at the other position to stop sound collection; and receiving a signal to be recognized from the microphone at the wake-up voice position.

[0064] According to the above method of the embodiment of the present invention, by first determining the wake-up voice position, audio signals at other positions can be suppressed, thereby maintaining the validity of the voice at the wake-up voice position, reducing the impact of noise signals at other positions on speech recognition, Reduce disturbance to wake-up voice location. Therefore, it is more conducive to obtaining accurate speech recognition results and improving user experience.

[0065] In an application example, a speech recognition system of a vehicle is taken as an example. Such as image 3 As shown, the interior...

Abstract

The embodiment of the invention provides a voice recognizing method, a voice recognizing device, a voice recognizing facility, and a storage medium. The voice recognizing method comprises the following steps: acquiring a plurality of paths of awakening voice signals coming from a plurality of positions; carrying out sound source locating on the plurality of paths of awakening voice signals, thus determining awakening voice positions; inhibiting audio signals on the other positions except the awakening voice positions, so that to-be-recognized signals are obtained; and carrying out voice recognition on the to-be-recognized signals. The awakening voice positions are determined first, the audio signals of the other positions can be inhibited, thus the effectiveness of the voice of the awakening voice positions is guaranteed, the influences of the noise signals of the other positions on voice recognition are reduced, and the interferences on the awakening voice positions are reduced.

Description

technical field [0001] The present invention relates to the technical field of voice recognition, in particular to a voice recognition method, device, equipment and storage medium. Background technique [0002] The current in-vehicle voice recognition system usually only allows voice input by a person at a specific location in a quiet environment. However, in the vehicle environment, there are often scenes where there are many people talking in the vehicle. For example, someone is on the phone, and at the same time someone else wants to initiate an operation such as navigation by voice. At this time, if the voice of the phone is recorded by the microphone of the car, it may cause many misidentifications of the car. Contents of the invention [0003] Embodiments of the present invention provide a voice recognition method, device, device, and storage medium to solve one or more technical problems in the prior art. [0004] In a first aspect, an embodiment of the present i...
