Embodiment Construction

[0022] In order to better understand the present application scheme, the technical solutions in the present application embodiment will be described in connection with the drawings in the present application embodiments.

[0023] Voice identification technology A biometric technology that identifies the identity of the speaker through voice. Voice identification technology is applied in multiple scenarios, such as phones, mobile phones, applications, access control systems, smart audio, robots, etc. However, in the actual application scenario, it may be affected by external factors such as environmental noise, reverberation, which leads to a decrease in accuracy of sound pattern recognition, and reduces the user experience.

[0024] In response to the above problems, the inventors present an automatic scene extended sound collection method, extracting the audio audio frequency in the first registered audio, and superimposing the environmental noise audio, obtaining the second regi...

Abstract

The invention discloses a voiceprint collection method for automatic scene expansion, and relates to the technical field of voiceprints. The method comprises the following steps: acquiring a first registered audio; extracting a voice audio in the first registered audio as a target audio; superposing the target audio with at least one environmental noise audio in a preset noise set to obtain a second registered audio; and based on a pre-trained human voice voiceprint model, feature extraction is performed on the second registration audio to obtain registration voiceprint features, and the registration voiceprint features are used for voiceprint verification. Thus, scene expansion is carried out in the voiceprint registration link, the universality for registering the voiceprint is improved, and then the robustness and accuracy of voiceprint recognition are improved.

Description

Technical field [0001] The present application relates to the field of voices, and more particularly to a sound pattern acquisition method of automatic scene extension. Background technique [0002] Voice identification technology is a biometric technology that identifies the identity of the speaker through voice. Voice identification technology is applied in multiple scenarios, such as phones, mobile phones, applications, access control systems, smart audio, robots, etc. [0003] However, in the actual application scenario may be affected by external factors such as environmental noise, thereby causing the accuracy of the sound pattern recognition to reduce the user experience. Inventive content [0004] In view of this, this application proposes an audio collection method for automatic scene extension. [0005] In the first aspect, the present application provides an automatic scene expansion of a sound pattern, the method comprising: acquiring a first registered audio; extrac...
