¿µ¹®³»¿ë¿ä¾à This standard describes the artificial voice used for objective evaluation of speech processing systems and devices, in which a single-channel signal with continuous activity is significant for measuring characteristics. 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 system. Two kinds of artificial voice are defined, reproducing respectively the spectral characteristics of female and male speech. The following time and spectral characteristics of real speech are reproduced by the artificial voice:

a) long-term average spectrum,
b) sgort - term spectrum,
c) instantaneous amplitude distribution,
d) voice and unvoiced structure of speech waveform,
e) syllabic envelop
