1. 语音的三要素：
音高 Pitch （音调）
由声源振动频率（Frequency）决定。单位：赫兹Hz音色 Timbre
声音的特性，由声源、声道确定。音强 Loudness （响度）
人主观的音量大小。由声音振幅（Amplitude）及人离声源的距离决定。单位：分贝dB
2. 和语音韵律（speech prosody）相关的三个重要特征：
音高 pitch时长 duration能量 energy
3. 和基频（F0）相关的特征：
基频 F0
F0 is strictly on the acoustic, measurable, production side.音高 Pitch
Pitch refers to the impression created in the hearer on the auditory side.Pitch represents the perceived fundamental frequency of a sound.Pitch is one of the three important features related to speech prosody (语音韵律). All languages use pitch to express emotional and other paralinguistic information (超语言学信息), and to convey emphasis, contrast, and other such features in what is called intonation (语调).音高范围 Pitch Range
Different speakers have different ranges of fundamental frequency.音高曲线 Pitch Contour
The pitch contour of a sound is a function or curve that tracks the perceived pitch of the sound over time.
声调 Tone
Tone is the use of pitch in language to distinguish lexical or grammatical meaning.
语调 Intonation
Intonation is variation of pitch, which carries the information of prosody.
