Abstract

The invention provides a voice processing method and a device thereof, wherein the method comprises the steps of segmenting a mixed value to N voice segments through end point detection, wherein N isa natural number which is higher than or equal with 2; performing Bayes information criterion (BIC) detection on two random adjacent voice segments in the N voice segments, abandoning abnormal voice segments in BIC detection, and obtaining effective voice segments of a target object. The voice processing method and the device thereof can settle a problem of incapability of quickly and effectivelyseparating the specific target voice from the fixed voice in speaking of a specific target, thereby realizing an effect of quickly separating the specific target voice from the mixed voice.

Description

technical field [0001] The present invention relates to the communication field, in particular to a voice processing method and device. Background technique [0002] The original speaker turning point detection scheme based on Bayesian Information Criterion BIC is aimed at separability, and generally ends up separating the mixed voices of multiple speakers. Technically no assumptions are made about the location of the turning point, and speech data from different speakers is generally retained as much as possible. In addition, this method is generally not used alone, such as calculating the distance between different data distributions, clustering, and so on. For situations where the speech duration of a specific speaker is dominant, and the speech duration of other people or noise is relatively low, and the speech content is less concerned, and more concerned about the characteristics of the speaker, a separable scheme is proposed. For this type of problem, the current so...
