Voice interaction awakening electronic device based on microphone signal, method and medium

Abstract

The invention provides an intelligent electronic device with a built-in microphone. The intelligent electronic portable device performs voice input-based interaction with a user through the followingoperations: processing a sound signal captured by the microphone to judge whether a voice signal exists in the sound signal or not; further judging whether the distance between the intelligent electronic device and the mouth of the user is less than a preset threshold value or not based on the sound signal collected by the microphone in response to the confirmation that the voice signal exists inthe sound signal; and, in response to determining that the distance between the electronic device and the mouth of the user is less than the predetermined threshold, processing the sound signal acquired by the microphone as voice input. The interaction method is suitable for voice input when the user carries the intelligent electronic device, the operation is natural and simple, the voice input steps are simplified, the interaction burden and difficulty are reduced, and the interaction is more natural.

Description

technical field [0001] The present invention generally relates to the field of voice input, and more specifically, to an intelligent electronic device and a voice input triggering method. Background technique [0002] With the development of computer technology, speech recognition algorithms are increasingly mature, and speech input is becoming more and more important because of its high naturalness and effectiveness in interactive methods. Users can interact with mobile devices (mobile phones, watches, etc.) through voice to complete various tasks such as command input, information query, and voice chat. [0003] On the point of when to trigger the voice input, the existing solutions all have some defects: [0004] 1. Physical key trigger [0005] After pressing (or holding down) a certain (or some) physical keys of the mobile device, the voice input is activated. [0006] The disadvantages of this solution are: physical keys are required; false triggering is easy; user ...

AI Technical Summary
