Abstract

PURPOSE: To lessen a change in attenuation characteristic as compared with an original voice and to obtain the voice natural in hearing sensation by providing an elimination means which eliminates the section of the predetermined conditions within the signals detected by a vowel detecting means and a joining means which connects the signals just before the section eliminated by the eliminating means and right after this section.
CONSTITUTION: An envelope stabilizing section detecting section 100 which detects the stable section st of the envelope, a compression section segmenting 200 which outputs the signal (2) eliminated of the specified section it and separated with time from the stable section st of the envelope and the joining section 300 which joins the signals (d) and separated with time and outputs a vowel compression signal (e) are provided. Then, only the stable and stationary voice section of the envelope is subjected to time base compression. Since the attenuation characteristic of the voice is identicial to the attenuation characteristic of the original voice i this way, the generation of the unnatural attenuation characteristic is obviated and the natural voice in the hearing section is obtd.
