In
linguistics,
intonation is variation of
pitch while speaking which is not used to distinguish words. (Compare
tone.) Intonation and
stress are two main elements of linguistic
prosody.
All languages use pitch
semantically, that is, as intonation, for instance for emphasis, to convey surprise or
irony, or to pose a question.
Tonal languages such as
Chinese and
Hausa use pitch to distinguish words in addition to intonation.
Rising intonation means the pitch of the voice increases over time;
falling intonation means that the pitch decreases with time. A
dipping intonation falls and then rises, whereas a
peaking intonation rises and then falls.
The classic example of intonation is the question-statement distinction.
For example, northeastern American
English, like very many languages (Hirst & DiCristo, eds. 1998), has a rising intonation for echo or declarative questions (
He found it on the street?), and a falling intonation for
wh- questions (
Where did he find it?) and statements (
He found it on the street.). Yes or no questions (
Did he find it on the street?) often have a rising end, but not always. The
Chickasaw language has the opposite pattern, rising for statements and falling with questions.
Dialects of British and Irish English vary substantially, with rises on many statements in urban Belfast, and falls on most questions in urban Leeds.
In the
International Phonetic Alphabet,
"global" rising and falling intonation are marked with a diagonal arrow rising left-to-right and falling left-to-right , respectively. These may be written as part of a syllable, or separated with a space when they have a broader scope:
He found it on the street?
Here the rising pitch on
street indicates that the question hinges on that word, on where he found it, not whether he found it.
Yes, he found it on the street.
How did you ever escape?
Here, as is common with
wh- questions, there is a rising intonation on the question word, and a falling intonation at the end of the question.
