      Sonority

      音響,響度

       

      A term in auditory phonetics for the overall loudness of a sound relative to others of the same pitch, stress and duration. Sounds are said to have an ‘inherent sonority’, which accounts for the impression of a sound’s ‘carrying further’. In a sonority scale, or sonority hierarchy, the most sonorous elements are assigned the highest value, and the least sonorous the lowest value. The centre of a syllable (the syllabic nucleus) is defined as the place where sonority is greatest (the sonority peak). Patterns of sonority sequence have been noted, leading to such observations as the sonority sequencing generalization: in any syllable, there is a segment constituting a sonority peak which is preceded and/or followed by a sequence of segments with progressively decreasing sonority values. The notion of visual sonority is used in the phonological analysis of the various features of sign language.

       

      聽覺語音學術語,指一個音相對其他音高、重音和音延相同的音的總體響度。語音各有其所謂的“固有音響”,能解釋有的音“傳得遠”的印象。在音響階或音響層級中,最響的成分指派有最高值,最不響的成分指派有最低值。音節的中心(節核)定義為音響最高的位置(音響峰)。研究者已注意到存在音響序列型式,從而導致音響定序概括這樣的觀察結果:任何一個音節中有一個音段構成音響峰,前頭和/或后頭跟著一個音響值逐漸下降的音段序列。視覺響度的概念用于手勢語各種特征的音系分析。
