Abstract

The invention provides an intelligent voice recognition method, which comprises: step 1: using short-term power and ZCR as features to distinguish silence and voice, and performing endpoint detection; step 2: dividing the voice signal after endpoint detection into multiple, etc. Long frame; Step 3: Obtain the voice signal feature through the dynamic change of audio power; Step 4: Perform user identity authentication of the smart POS machine based on the comparison result of the voice signal feature. The invention proposes an intelligent voice recognition method, which realizes local storage, comparison and calculation of identity authentication data of intelligent POS machine terminals, without the need to configure hardware encryption devices, and without uploading to the payment platform, which is more secure.

Description

technical field [0001] The invention relates to speech recognition, in particular to an intelligent speech recognition method. Background technique [0002] At present, the network security of sales terminals, especially the security of smart POS machines, is attracting attention, and the security of information transmission through smart POS machines has attracted increasing attention. In the current application of smart POS machines, user authentication with user name and password is adopted, digital certificates are issued to smart POS machine users, and the non-exportability of hardware password terminal private key is used to strengthen the identity security of users. However, any form of hardware encryption device needs to be connected to a physical device outside the smart POS machine, which further reduces the ease of use of the solution and increases the complexity of the user's operation. For the fingerprint identification of the prior art, the identification info...
