A SPEECH REINFORCEMENT METHOD USING SOFT DECISION UNDER FRA-END NOISE ENVIRONMENTS

摘要

PURPOSE: voice method of addition, which is passed through after only being amplified using the voice signal for being provided to the quality for significantly improving agricultural product pollution under soft decision far-end noise environment by clear signal acquisition speech signal power, accurately to be estimated. ;CONSTITUTION: a kind of LSAP (local speech shortage Probability), the estimation for obtaining clearly voice spectrum utilize LSAP. By hearing end background noise estimation, the estimation of Background Noise Power. Voice gain amplifier is modified to the power of the clearly frequency spectrum of speech and ambient noise. The enhancing of only clear voice signal clearly voice spectrum, Background Noise Power and sound gain amplifier. ;The 2010 of copyright KIPO submissions
