Abstract

The invention provides a voiceprint authentication method and a voiceprint authentication device. The voiceprint authentication method comprises the steps as follows: showing a tooltip text to a user, wherein the tooltip text is the combination of phrases pre-registered by the user; acquiring the speech of the user generated when the user reads the tooltip text; and when the speech and the tooltip text are consistent, acquiring a pre-established registration model and determining the voiceprint authentication result according to the speech and the registration model. The method ensures that users do not need to speak too long in authentication and ensures the variability of the speech content, thus preventing cheating in recording.

Description

technical field [0001] The invention relates to the technical field of identity authentication, in particular to a voiceprint authentication method and device. Background technique [0002] The current voiceprint authentication technology is mainly divided into two types: text-independent and text-dependent. The text-independent voiceprint authentication technology does not distinguish what the user said, while the text-related voiceprint authentication technology requires that what the user said must be consistent with the registration. The two technologies have their own advantages and disadvantages: the text-independent voiceprint verification technology is more flexible because it does not limit the content of the user's speech, but in order to cover as large a sample space as possible, the user needs to speak for a long time; the user voice of the text-related technology is usually relatively Short, but the text must match the registration, making it impossible to prev...
