Production of Short and Long Finnish ­Vowels with and without Noise Masking
Production of Short and Long Finnish ­Vowels with and without Noise Masking

Summary/Abstract: In order to further examine the possible quality differences between produced short and long Finnish vowels, we studied the formant frequencies F1–F4 and duration of the eight Finnish vowels /a/, /e/, /i/, /o/, /u/, /y/, /æ/ and /ø/ when uttered in carrier words (e.g., /tili/ — /tiili/) in two different masking conditions and without a noise mask. Babble noise at 92dB SPL was used to simulate a loud, crowded cocktail party, and pink noise at 83dB SPL an environment with the ­maximum noise level allowed for continuous working. Minor quality differences were found between the short and long vowels. Noise masking caused a significant prolongation of produced short vowels, and a significant increase in the F1 frequency.
