ITU-T P.50 FRENCH-1999 仿真口声.12号研究组.承包单:5/25/2000

The "artificial voice" described in this Recommendation reproduces the characteristics of human speech for the purpose of characterizing linear and non-linear telecommunication systems and devices, which are intended for the transduction or transmission of speech. The artificial voice is a signal that is mathematically defined and that reproduces the time and spectral characteristics of speech which significantly affect the performances of telecommunication systems. Two kinds of artificial voice are defined, reproducing respectively the characteristics of female and male speech.
