Abstract

The invention discloses a model library establishing method and device, a voice recognition method and device, a facility and a medium. The model library establishing method comprises the following steps: acquiring a training sample set; if the sample number of original voice data in the training sample set is greater than a preset threshold value, establishing a current grading model according totraining voice characteristics extracted by the original voice data, and dividing the original voice data into at least two current training subsets according to the model grading logic; if the sample number of the current training subsets is greater than the preset threshold value, updating the current training subsets to the training sample set; and if the sample number of the current trainingsubsets is not greater than the preset threshold value, determining the current training subsets as identification data sets. With the method, a recognition server can rapidly match the identificationdata set in which to-be-detected voice data are located according to the model grading logic of a grading model library, so that the voice recognition efficiency is improved.

Description

technical field [0001] The invention relates to the field of voiceprint recognition, in particular to a method for establishing a model library, a voice recognition method, a device, equipment and a medium. Background technique [0002] The application of voiceprint recognition is more and more favored by system developers and users. The world market share of voiceprint recognition is second only to biometric recognition of fingerprints and palmprints, and it has a rising trend. The advantages of voiceprint recognition are: (1) the acquisition of voice containing voiceprint features is convenient and natural, and voiceprint extraction can be completed unconsciously, so the user's acceptance is also high; (2) the cost of voice acquisition is low, and the use of Simple, a microphone is enough, and no additional recording equipment is needed when using communication equipment; (3) Suitable for remote identity confirmation, only a microphone, telephone or mobile phone is needed ...
