Summary Loudness Pitch is used in words with contrastive tone or stress. Duration is used in words with contrastive stress or tone but is also manipulated for use voicing, word size, and vowel quality. Loudness is used in words with contrastive stress and may also be used to distinguish tones, but it is never as much <strong>of</strong> a major acoustic correlate <strong>of</strong> a phonological contrast as pitch or duration are. It is also used to distinguish vowel quality. DiCanio (DDL) Features 24/3/10 24 / 24
