Speech rhythm vowel durations highly variable: language sounds stress-timed Languages with vowel reduction: English, Dutch, German If vowel durations similar: language sounds syllable-timed Languages such as French and Spanish which do not have vowel reduction Low and grabe 1995. Ramus et a/ 2000
Speech rhythm ◼ If vowel durations highly variable: language sounds ‘stress-timed’ ◼ Languages with vowel reduction: English, Dutch, German ◼ If vowel durations similar: language sounds ‘syllable-timed’ ◼ Languages such as French and Spanish which do not have vowel reduction Low and Grabe 1995, Ramus et al 2000
Speech rhythm though there is no evidence for meter in speech there is an acoustic basis for cross-language differences in speech rhythm But what about the stress-timing/syllable-timing dichotomy? Linguists proposed that the worlds languages would fall into two rhythm classes Is there evidence for this dichotomy from durational variability data?

Two rhythm classes? The following comparisons are required 1)Acomparison of data from languages cited in the literature as stress-timed and languages cited as syllable-timed (2 )A comparison of the data in(1)with evidence from unclassified languages
