Key concepts: the Key concepts: the phonephone

Each time a speech sound is produced it is different

Each time you produce a /t/ it will be ever so slightly different

Hence the concept of the phone: a physical realisation of a speech sound

Key concepts: the Key concepts: the phonemephoneme The smallest speech sound that has linguistic

value When a series of phones are similar in terms of

articulation and can be distinguished from another group in terms of meaning and collocation, the group is given a name e.g. /t/. This is a phoneme.

The phoneme is an abstract term, specific to a particular language.

Speech sounds can be divided into three Speech sounds can be divided into three main types:main types:

Stops (or plosives) and affricatesFricativesVowels and approximants

11

We will first focus on We will first focus on stopsstops and and fricativesfricatives

which are classified according towhich are classified according to the place in which they are articulated

whether they are voiced or not (vibration of vocal folds)

whether they are oral or nasal (for stops only)

Places of articulationPlaces of articulation

A stop is composed of three A stop is composed of three phasesphases

ClosureHold (the passage of air from the lungs is

blocked)Release – the difference in air pressure

between the area behind the closure and the atmosphere results in a small explosion

/p/ and /b/ are voiceless and voiced bilabials i.e. produced with both lips

/t/ and /d/ are voiceless and voiced alveolars

/k/ and /g/ are voiceless and voiced velars

FricativesFricatives

are created by forming a constriction through which air from the lungs may pass, but not freely.

this lack of freedom causes audible turbulence, or friction, hence the name fricative.

AffricatesAffricates

These may be considered as stop + fricative

41

An affricate is composed of the following An affricate is composed of the following stagesstages

ClosureHoldA small opening instead of the complete

opening of the stop.This small opening causes friction just like

a fricative

42

Affricates - articulationAffricates - articulation

The place of articulation is always the same for both stages

Affricates are always either voiced or unvoiced
