Sound Drills.

Combinations of voiceless consonants with [r]

[tr, pr, kr, str, skr, 0r, fr, 4r, sr]

In the clusters of voiceless consonants with the sonorant [r] complete of partial devoicing of the sonorant takes place – progressive assimilation affecting the work of the vocal cords. The sound [r] is completely or almost completely devoiced when it is preceded by a voiceless plosive consonant [p, t, k] in a stressed syllable: train, pride, cry.

In an unstressed position, at a word boundary or when [p, t, k] are preceded by [s] or some other fricative consonant the devoicing of [r] is partial: waitress, temperature, spread, quite right. A similar (of partial devoicing) both in stressed and unstressed syllables is produced when [r] is immediately preceded by a fricative consonant: friend, Geoffrey, shrewd, three, fruit, that’s right.

Combinations of alveolar and interdental consonants with [r]

[tr, dr, 0r, 8r]

In some of these clusters assimilation affecting the place and the manner of articulation can be observed. Thus under the influence of the post-alveolar [r] the alveolar consonants [t, d] in the clusters [tr, dr] become post-alveolar.

The clusters [tr, dr] are actually characterized by double (reciprocal) assimilation because the the sonorant [r] is modified as well: under the influence of the noise consonants [t, d] it becomes fricative, and after [t], as was mentioned above, it is also devoiced.

In the clusters [0r, 8r] the post-alveolar frictionless sound [r] is often replaced by an alveolar tap, or a flapped variety of [r]: a single brief tap is made by the tip of the tongue on the teethridge. In the cluster [0r], besides, there is partial devoicing of the sonorant [r].
