摘要
通常将普通话单音节的声调F0曲线划分成“弯头段”、“调型段”和“降尾段”。考察“调型段”的具体位置和相对长度,对普通话语音教学,对开发语音识别和语音合成系统,都是很有意义的。本文使用两大类合成刺激连续体,通过辨认试验,初步确定了“调型段”在音节F0曲线上的位置,即一个单音节,不论是清声母音节,还是浊声母音节,也不论是何种声调和调域,其声调知觉中心(P-CT)的位置位于韵母段中部,而且,只要“调型段”的长度为浊音段的一半左右,就可能被感知成相应的调类。
A Fo-contour of syllibIes in Standard Chinese is generally divi-ded into the onset-curving segment, tone segment and offset-cur-ving segment. It is beneficial for teaching speech and developingspeech recognition and speech synthesis systems to investigate theconcrete location and relative length of the tone segment. The lo-cations of the tone segment on Fo-contour is determined on thewhole through a sequence of identification tests using two typesof the continua of synthetic stimuli. The perceptual center oftones(PCT)of a monosyllable, whether its initial is unvoiced or voicedand no matter which type of tone and the pitch range it has, islocated in the middle part of its final. So long as the length of thetone segment is about a half of that of the voiced part, the corres-ponding tones may be perceived.
