Embodiment Construction

[0017] Take the user's mobile phone as an example. The voice input method of the present invention is downloaded and installed in the mobile phone. When using the voice input for the first time, if the voice input is not initialized, when the voice input icon is clicked for voice input, the system will pop up a prompt box asking the user to First enter the voice system to initialize voice identity authentication.

[0018] During voice identity authentication, the voice input system will give a sentence, for example, given the sentence [developing an intelligent voice input method is a very complex and difficult task], the user is required to speak in standard Mandarin and habitual daily dialect, and Voice collection is divided into five levels: loud speaking, normal speaking, soft speaking, soft speaking, and whispering speaking. If the sound of any level does not meet the threshold requirements, the system will ask the user to speak again and prompt to increase or decrease the...

Abstract

A noise elimination method for speech input is disclosed and comprises a speech initialization phase and a speech recognition phase. The method is characterized in that users having speed input permissions go through speech identity authentication in the initialization phase, and sound spectrums of the users are sensed; in the speech recognition phase, recognizing operation is performed on sound spectrums of the users having permissions that successfully pass the identity authentication, speeches are converted into texts that are then output, and other sound irrelevant to the sound spectrums of the users having permissions is filtered and removed as noise.

Description

technical field [0001] The invention is applied to desktop computers, notebook computers, mobile phones, tablet computers and other voice input platforms. Background technique [0002] Now voice input products are becoming more and more popular, and voice input application scenarios are becoming more and more common. However, speech input is always more or less affected by noise interference in the application scene, and how to eliminate scene noise to improve the speech recognition rate is a key issue. [0003] We all know that a certain household has installed an access control system and uses face recognition to open the door. The user first needs to initialize the identity authentication of the access control system, that is, let the access control system collect the user's face, and perceive and authenticate his face. After initializing the identity authentication, the user can use his Facebook to open the door at any time. For other people who have not authenticated ...
