Embodiment approach

[0094] Since the process of the electronic device judging whether the interaction instruction corresponding to each received voice signal is a wake-up instruction is the same, as an embodiment of the present invention, the separate judgment of the interaction instruction corresponding to each received voice signal The step of whether the command is a wake-up command may include:

[0095] Determine whether the interactive instruction corresponding to each received voice signal is a wake-up instruction in the following manner:

[0096] Filtering the target voice signal, filtering out the voice signal whose frequency belongs to the preset frequency range in the target voice signal, and judging whether the interactive command corresponding to the filtered target voice signal is a wake-up command, wherein the target voice signal is: a speech signal received.

[0097] The frequency range of the human voice is generally 100-20000Hz, so the voice signal that does not belong to this f...

Abstract

The embodiments of the invention disclose a sound source positioning method, a sound source positioning device and an electronic apparatus. The method includes the following steps that: when being in a sleep state, the electronic apparatus continuously receives speech signals; whether an interaction instruction corresponding to each of the received speech signals is a wake-up instruction is judged; if the interaction instruction is not a wake-up instruction, the sound source direction of the speech signal is recorded and is adopted as a first type sound source direction; if the interaction instruction is a wake-up instruction, the electronic apparatus is switched from the sleep state to a work state, and the sound source direction of the speech signal is positioned and recorded, and is adopted as a second type sound source direction; and the sound source direction of a user is positioned according to the first type sound source direction and the second type sound source direction. According to the sound source positioning method, the sound source positioning device and the electronic apparatus provided by the embodiments of the invention, the sound source direction of the user is positioned according to the first type sound direction of the speech signal received under the sleep state and the second type sound source direction of the speech signal received under the work state, and therefore, the accuracy of the sound source positioning of the user is greatly improved, and user experience is better.

Description

technical field [0001] The invention relates to the technical field of voice signal processing, in particular to a sound source localization method, device and electronic equipment. Background technique [0002] At present, there are more and more products on the market with voice interaction functions, such as electronic devices such as smart speakers and robots. When these electronic devices receive a wake-up command, they will turn from a sleep state to a working state, and start to receive voice signals through the microphone array, and then can recognize and analyze the voice signals, thereby responding to the interactive commands corresponding to the voice signals. Obviously, in the process of product function realization, sound source localization is very important. Only by accurately locating the direction of the user's sound source can the voice signal sent by the user be accurately obtained and the correct response behavior can be performed. [0003] After receivi...
