The “r” could be a trill, as in Spanish • Glides, e.g., [j] as in yes and [w] as in wood. perro (=‘dog’), in which case it is transcribed as [r]. • The “r” could also be a retroflex, as the case is in • Some English speakers produce a voiceless American and Canadian English, and is transcribed as glide at the beginning of words like when, [®] in the IPA. which, and where. It is transcribed as [„]. • Another sound commonly identified with “r” is the Wheat thins flap, which occurs in North American English in words like writer and rider. This sound is transcribed as [R].

Voicing Describing consonants

3 English consonants Aspiration

• The same consonant can also be pronounced differently in different positions in the word. • For example, English voiceless stops (p, t, k) are produced with an extra puff of air when occurring initially. Compare your pronunciation of the [p], [t], and [k] sounds in both words in each of the following pair: pan vs. span tar vs. star cool vs. school

4 Nonpulmonic consonants Articulatory sequence for an Ejective [k’]

• Human languages also have consonants that are produced by nonpulmonic airstream, either glottalically or velarically.

• Glottalic airstream gives us ejectives and implosives, whereas velaric airstream gives us clicks.
