Abstract

Source-filter interaction explains the drop in pitch in voiced consonant due to constriction in the vocal tract during vowel-consonant-vowel (VCV) production. In this work, a perceptual study is conducted where the pitch contour in the voiced consonant region is modified to four different levels and a listening test is performed to assess the naturalness of the VCVs synthesized with the modified pitch contour. The listening test with 30 listeners shows no statistically significant difference between the naturalness of the original and synthesized VCVs with modified pitch indicating that pitch drop due to source-filter interaction may not be critical for the perceived naturalness of VCVs.
