Intonation (speech)
Intonation is about the variation in pitch of speech which may change meaning. How something is said may change its meaning. All spoken languages use this tactic.
- "He found it on the street?" It is a question when street in emphasised (technically, rising pitch).
- "Yes, he found it on the street". (street not emphasised, not rising pitch)
The study of intonations is part of prosody.[1][2]
A simple example which shows how important prosody is. A parent says to a child "well done". Without some annotation, one can't decide whether the child has indeed done well, or whether it has {say} knocked a glass of milk over.
