摘要

So far, the voice data network connection is going spread for inexpensive telephone 6ystem such as Internet phone. As VoIP and cellular telephone uses digital voice data compression technique. But, the voice data compression always degrade the telephone call quality. I use speech recognition software to measure the voice audio communication quality with the long letter word and digital voice generator software. The speech-recognition software makes judgement for the point "whether language is clearly heard". This digital voice transmittion evaluation methods improve the voice data communication and compression techniques for such as a digital cellular phone and VoIP, were considered.
