Tones and tone languages
• When we speak, we constantly vary the pitch of our
voice. Tone is the overall behaviour of pitch in a
syllable.
• Although in English, a word such as ‘yes’ and ‘no’ can
be spoken with different tones, no English speakers
would say that the meaning of the word is different with
different tones.
• English is one of those languages that do not use tone
to distinguish the meanings of words, though tones or
pitch differences are used for other purposes. Such
languages are called intonation languages.

Tone languages
• A tone language is one in which the tone can
determine the meaning of a word and a
change from one tone to another can
completely change the meaning of a word. In
other words, substituting one distinctive tone
for another on a particular word can cause a

change in lexical meaning of that word.
• E.g. Vietnamese, Chinese

Functions of English tones
1.

The level tone.

•

This tone almost always conveys a feeling of saying
something routine, uninteresting or boring. E.g.

•

A teacher’s calling the names of the students from a
register and the students respond the teacher with
‘Yes’.

•

Respondents answer surveys or questionnaires.

2.

The falling tone.

•

This tone is usually regarded as more or less neutral.
It is said to give an impression of ‘finality’.

•

If someone is asked a question and replies ‘yes’ or
‘no’ with a falling tone, it will be understood that the
question is now answered and there is nothing more
to be said.

•

How many dogs have you got?

Two

•

What was the weather like?

Wet

•

Have you finished?

Yes

Tone units
• A tone unit is a group of syllables over which a tone
extends. It is also referred to as an ‘intonation group’ or
a ‘tone group’.
Is it you?

You have sold your car?
• In its smallest form, the tone unit may consist of only
one syllable
James?

Four?

• The syllable which carries the tone in a tone unit is
called the ‘tonic syllable’.

Is it /you
• The third syllable
• is more prominent than the other two
• carries a level tone
• is a tonic syllable
• The other two syllables
• are less prominent
• said on a level pitch
• “is it you” is an utterance of three syllables, consisting
of one tone unit. The only syllable that carries a tone is

Tonic syllable
• is the syllable which carries the tone in a
tone-unit
• Each tone-unit has one and only one tonic
syllable. This means that the tonic syllable is
an obligatory component of the tone unit.

14


The head

• The head (H) is all that part of a tone-unit that
extends from the first stressed syllable up to but not
including the tonic syllable.
 If there is no stressed syllable before the tonic
syllable, there cannot be a head.
e.g.

l

give me \those

l

in an \hour
15


The pre-head
• The pre-head (PH) is composed of all the unstressed

syllables in a tone-unit preceding the first stressed
syllable.
• Pre-heads are found in two main environments:

• When there is no head: in an \hour
PH
• When there is a head: in a ’little ’less than an hour
PH

H

The tail
• Any syllables between the tonic syllable and the
end of the tone unit are called the tail
•
