Problems solved by technology

In order to avoid the influence of noise, airflow and air pressure, common noise reduction methods such as LMS (least mean square adaptive filter), spectral subtraction, and Wiener filtering are often used. However, these methods cannot effectively solve all problems of poor radio quality, especially In open indoor scenes that are prone to reverberation, the requirements for voiceprint collection will not be met

Embodiment Construction

[0032] This application collects the tester's voiceprint through solid conduction to avoid the impact of the open indoor environment and noise environment on voiceprint collection, and compares the voiceprint collected through solid conduction with the voiceprint through air conduction to determine the former Whether the collected voiceprint is a valid voiceprint, so that noise interference can be effectively eliminated.

[0033] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the application. Obviously, the described embodiment is only It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative effor...

Abstract

The embodiment of the application discloses a voiceprint detection device and method. The voiceprint detection device comprises a first pickup sensor unit, a second pickup sensor and a main control analysis unit. The first pickup sensor unit collects a first voiceprint signal of a testee by means of contacting the testee. The second pickup sensor unit collects a second voiceprint signal conductedthrough air; and the main control analysis unit is used for comparing the first voiceprint signal with the second voiceprint signal when the testee makes sounds, and determining whether the voiceprintis one of the same person or not. With a solid conduction method, the influence of an open indoor environment and a noise environment on voiceprint collection is avoided.

Description

technical field [0001] The present application relates to the technical field of voiceprint testing, in particular to a voiceprint testing device and method. Background technique [0002] In the field of voiceprint, air-borne sound is often affected by air pressure, airflow, background noise, etc., and it is easy to interfere with the product during the radio reception process. In order to avoid the influence of noise, airflow and air pressure, common noise reduction methods such as LMS (least mean square adaptive filter), spectral subtraction, and Wiener filtering are often used. However, these methods cannot effectively solve all problems of poor radio quality, especially In open indoor scenes that are prone to reverberation, the requirements for voiceprint collection will not be met. Contents of the invention [0003] The embodiment of the present application provides a voiceprint detection device and method, which avoids the influence of the open indoor environment an...
