Abstract

A voiceprint detection method and apparatus. The method comprises: when a matching degree between a voiceprint feature of an audio signal portion and a pre-set voiceprint feature exceeds a pre-set threshold value, and a matching degree between an exhaled airflow feature of a determination signal portion and an exhaled airflow feature of the audio signal portion exceeds the pre-set threshold value, determining that a voiceprint detection result indicates that the detection has succeeded (S206). By means of the voiceprint detection method and apparatus, the security of voiceprint unlocking is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and device for voiceprint detection. Background technique [0002] With the development of mobile terminals and intelligent interaction, terminal devices have become an indispensable part of people's daily life. In order to protect the private information stored in the terminal device by the user, most terminal devices provide a password-protected unlocking function. When the terminal device is locked, the user can only unlock the terminal device by entering the correct password. At present, there are many methods for unlocking a terminal, and since voice unlocking has higher security than other unlocking methods, it has become a widely used unlocking method. The terminal device or application software provides the function of voice unlocking, through voice unlocking to verify the user, further unlock the terminal device, or provide services, etc. [0003] At prese...
