<p><P>PROBLEM TO BE SOLVED: To provide a voice communication system in which received voice is processed so as to be made easy to hear so that all user's audible environment and tastes are reflected as regards a voice processing technology by which the received voice is made easy to hear by changing the sound feature quantity of the received voice. <P>SOLUTION: An acoustic analysis part 101 analyzes the feature quantity of a signal of an input transmitted voice. More specifically, the acoustic analysis part 101 time-divides the transmitted voice, and applies acoustic analysis to the time-divided transmitted signal to calculate the feature quantity such as a speaking speed and a pitch frequency. A reference range calculation part 102 performs statistic processing related to an average value and dispersion and the like, with respect to the feature quantity calculated by the acoustic analysis part 101, and calculates a reference range. A comparing part 103 compares the feature quantity calculated by the acoustic analysis part 101 with the reference range calculated by the reference range calculation part 102, and outputs a comparison result. On the basis of the comparison result output by the comparing part 103, a voice processing part 104 applies processing treatment to the signal of the input received voice, so that the received voice is processed to be easy to hear, and the voice processing part then outputs the processed received voice. The processing treatment includes, for example, sound volume changes, speaking speed conversion, and/or a pitch conversion. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
