Assimilation. Assimilation is a phonetic process as a result of which one of the sounds becomes fully or partly similar to the neighbouring sound

Assimilation is a phonetic process as a result of which one of the sounds becomes fully or partly similar to the neighbouring sound.

Assimilation can affect different characteristics of a sound, and its types are numerous. Some of the most frequent types are:

1. Alveolar [t], [d], [n], [l], [s], [z] are replaced by their dental variants when immediately followed by the interdental [θ] or [ð].

e.g. tenth, on the desk

2. The sonorants [m], [n], [l], [w], [r], [j] are partly devoiced when preceded by the voiceless consonants.

e.g. rush – crush, got wet

3. Consonants followed by [w] become slightly rounded.

e.g. twin, swift

4. In a cluster of two plosives, when the positions of the organs of speech are the same for both consonants, the first plosive loses its plosion.

e.g. bookcase, that child

5. When the positions of the organs of speech are different, the first plosive has an incomplete plosion.

e.g. talked, good book

6. When a plosive is followed by the syllabic [n] or [m] the nasal plosion is produced.

e.g. shipmate, escape noisily

7. When a plosive is immediately followed by the sound [l] the lateral plosion is produced.

e.g. black, settle, it lasts

8. In rapid speech ‘do you’ often becomes [d u].

e.g. Do you know his name? [dZu nәu hiz neim]

Exercise 63

Listen to the phrases on the tape, put them down, work out their meanings, explain the difference in the way they sound.
