Formant frequency patterns in Russian VCV utterances.

Previous studies have sought to establish the significance of various parameters in the determination of the patternings of Russian formant frequency trajectories in vowel-consonant-vowell (VCV) syllables. In the present study, 9600 measurements of first and second formant frequency were made on Russian VCV nonsense words. Variance for speakers was controlled through regression. Stepwise multiple regression was employed to determine the relative contributions of six predictors to the explanation of the patternings of first and second formant frequency in the test words. The six predictors included the height of the first and second vowels, the fron/back dimensionality of the first and second vowels, the place of articulation of the consonant, and the palatalization or nonpalatalization of the consonant. Results of the regression analyses are summarized. The regression coefficients for the useful predictors of the various dependent variables comprise a model of formant frequency patterns in Russian VCV utterances.

A before and after for tonogenesis.

The development of tone in Panjabi from the loss of certain consonants has often been cited as an instance of the consonantal origins of a tonal system. Acoustic data demonstrating the correlation between Panjabi tones and Hindi consonants are presented. Panjabi high tone matches a higher fundamental frequency on a Hindi vowel preceding a breathy voiced consonant. Panjabi low tone matches a lower fundamental frequency on a Hindi vowel following a breathy voiced consonant. It is interesting that the data exhibit the spread of the consonantal effect throughout the entire word.
