Embodiment 1
[0057] Embodiment 1 of the present invention discloses a voiceprint-based identification method, such as figure 1 shown, including:
[0058] Step 101, prompting the user to input a voice password when the service application request requires the user to confirm the identity information;
[0059] Step 102, receiving the voice data of the user, and converting the voice data into text information;
[0060] Step 103, matching the text information with the text information in the preset voice password previously set by each user in the user list;
[0061] Step 104, if the voice password is matched successfully, acquire the voiceprint feature of the user;
[0062] Step 105, matching the voiceprint features with the preset voiceprint features previously set by each user in the user list to obtain a matching degree;
[0063] Step 106, if the matching degree is greater than a preset identification threshold, confirm that the user's identification is successful.

Abstract
The invention provides a voiceprint based identity recognition method and device. The voiceprint based identity recognition method comprises the steps of prompting a user to input a voice password when a service application request requires the user to confirm identity information; receiving the voice data of the user and converting the voice data into text information; matching the text information with text information in a preset voice password set by each use in a user list in advance; acquiring a voiceprint feature of the user if the voice password is successfully matched; matching the voiceprint feature with a voiceprint feature set by each user in the user list in advance, and acquiring a matching degree; and confirming the identity of the user is successful recognized if the matching degree is greater than a preset recognition threshold. The voiceprint based identity recognition method realizes recognition for the identity of a user through voice and voiceprint, and is convenient to implement, accurate in recognition and high in safety.
Description
