Phonetic studies of Zulu have suggested that tonal depression and not VOT is the main acoustic cue to the phonological voiced/voiceless distinction. This study shows that VOT is a significant acoustic correlate between all voicing distinctions in both the plosive and click accompaniment series; its primacy is dependent on speech condition. Isolated and slow conditions show a significant difference across all three distinctions for both series. The fast context illustrates near VOT collapse between voiced/voiceless as has been previously documented. Additional data confirm another acoustic effect (vowel lengthening) of depressor consonants and permit the examination of the difference between velar plosives and click accompaniment releases.
