A Duration Study of Speech Vowels Produced in Noise

In this paper we present a duration study for vowels produced in several noisy and non-noisy conditions in a "s-s" context. While confirming results from earlier work, such as a vowel duration increase when vowels are produced in noise, we also found that the type of noise influences vowel duration. While the type of masking noise affects the vowel duration it does not affect the duration of the preceding "s" consonant. This result does not hold for articulated speech, which lengthens the duration of the preceding "s" consonant compared to the quiet speech case while providing the larger vowel duration increase among the different speaking styles studied.
