Thirty-seven speakers produced words with a /CCəC/ structure containing a voiceless stop in the underlyingly pre-vocalic position (e.g., /skəf/) across speaking styles. Vowelless forms of these words occur for about 11% of productions. When these words surface as vowelless, they are produced with a longer aspiration than when they are produced with a vowel. Thus, vowellessness in Tarifit consists of articulatory restructuring of words involving aspiration lengthening, possibly in addition to either vowel deletion or devoicing.
