Reduction

Reduction is a historical process of weakening, shortening or disappearance of vowel sounds in unstressed positions. This phonetic phenomenon, as well assimilation, is closely connected with the general development of the language system. Reduction reflects the process of lexical and grammatical changes.

Reduction is realized:

a) in unstressed syllables within words, eg. demonstrative

b) in unstressed form-words, auxiliary and modal words, personal and possessive pronouns within intonation groups and phrases, eg. What do you think you can do? (Weak forms)

Three different types of reduction are noticed in English:

1. Quantitative reduction, i.e. shortening of a vowel sound in the unstressed position, affects mainly long vowels, eg [hi: - hiJ - hI].

When does he come? [→wen dΛz hI  ˛kΛm].

2. Qualitative reduction, i.e. obscuration of vowels towards [ə, Ι, υ ], affects both long and short vowels, eg can [kæn – kən].

You can easily do it.  [ju kən → i:zIlI ˛du: It].

Vowels in unstressed form-words in most cases undergo both quantitative and qualitative reduction, eg [tu: – tu - tυ].

3.  The third type is the elision of vowels in the unstressed position, eg I’m up already [aIm Λp  ˛o:lredI].
