Studies of the voice source during speech have been concerned mostly with variations in fundamental frequency and overall amplitude. However, the source variations also include spectral characteristics and the harmonics-to-noise ratio which reflect changes in glottal abduction and vocal fold tension. The present study reports detailed measurements of voice source aerodynamics during transitions between consonants and vowels and between vowels and consonants. Air flow, oral air pressure and glottal opening were recorded from two subjects producing reiterant speech with the vowel /0/ and different voiced and voiceless consonants. The flow signal was inverse-filtered to obtain an estimate of the glottal pulse. The results show considerable influences on the source from the consonant both before the end of the preceding vowel and after the onset of the following vowel. These influences are most marked for voiceless consonants, where the source is breathy at both vowel offset and onset. The observed source variations can be rationalized with reference to aerodynamic and my odynamic factors during vowel offset and onset.
