Measures of native and non-native rhythm in a quantity language.
The traditional phonetic classification of language rhythm as stress-timed or syllable-timed is attributed to Pike. Recently, two different proposals have been offered for describing the rhythmic structure of languages from acoustic-phonetic measurements. Ramus has suggested a metric based on the proportion of vocalic intervals and the variability ( SD) of consonantal intervals. Grabe has proposed Pairwise Variability Indices (nPVI, rPVI) calculated from the differences in vocalic and consonantal durations between successive syllables. We have calculated both the Ramus and Grabe metrics for Latvian, traditionally considered a syllable rhythm language, and for Latvian as spoken by Russian l…
Sixty years of bilingualism affects the pronunciation of Latvian vowels
For fifty years after World War II, Latvia was incorporated into the former Soviet Union. Although in theory the use of regional languages was not discouraged, in practice knowledge of Russian was obligatory. Since 1991, Latvian has again become the official language, and knowledge of Russian is widespread but optional. These political events have created a natural experiment in the effects of almost universal bilingualism on a language. To assess the impact on pronunciation, native speakers of Latvian, ranging from retirement age to teens, were recorded reading a word list and a short narrative. Vowel pronunciation differed across the generations both in quantity relationships and in forma…
