Acoustic and Production Pilot Studies of Speech Vowels Produced in Noise

We conducted two pilot studies: 1) to evaluate the influence of speech loudness on acoustic parameters, and 2) to analyze inter-articulatory relationships in vowel production in noisy and non-noisy conditions. The acoustic study revealed that the tense and lax vowel quadrangles (for the male and female speakers) tend to shift upward with increased vocal loudness (especially for the lax vowels). The production study brought to light that: 1) the type of noise influences speech production, and 2) the modification of speech production due to background noise is speaker-dependent and context-dependent.
