Embodiment Construction

[0088] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0089] The present disclosure is aimed at the voice input triggering of intelligent electronic devices, and determines whether to trigger the voice input application based on the internal characteristics of the sound captured by the configured microphone, wherein traditional physical button triggering, interface element triggering, and wake-up word detection are not required, and the interaction is more natural. Putting the device in front of the mouth triggers voice input, which is in line with user habits and cognition.

[0090]The present disclosure will be continued from the following aspects: 1. Voice input triggering based on the characteristics of wind noise when people speak, specifically, directly start voice input by recognizing the voice ...

Abstract

The invention provides an electronic device equipped with a microphone. The electronic device is provided with a storer and a central processing unit, computer executable instructions are stored on the storer, when the computer executable instructions are executed by the central processing unit, the following actions can be performed: a sound signal collected by the microphone can be analyzed, whether the sound signal contains a speech of person speaking or not and whether the sound signal contains a wind noise generated by airflow generated by person speaking hitting against the microphone ornot are identified, response is to determine that the sound signal contains the sound of person speaking and the wind noise generated by the airflow generated by user speaking hitting against the microphone, and the sound signal is processed as speech input of a user. An interactive method is suitable for conducting speech input when the user carries the intelligent electronic device, operation is natural and simple, speech input steps are simplified, and the interaction burden and difficulty reduced, so that 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 ...
