Abstract: This paper explores perceptual salience of voice source parameter manipulation in signaling prominence in the absence off0variation. Synthetic stimuli were generated based on an inverse filtered all-voiced utterance “We were away a year ago.” A global waveshape parameterRdwas manipulated in the stimuli to enhance prominence in the two potentially accentable syllables WAY and YEAR and to provide voice source deaccentuation post-focally. The manipulations were intended to mimic an increase in phonatory tension in the prominent syllable while decreasing it in the post-focal material.f0was kept constant. Two listening tests were conducted in which participants rated the perceived prominence of the potentially accentable syllables in the manipulated utterances on a continuous visual analog scale. The results suggest that perceived focal prominence can be achieved by source variation in the absence off0modulations, although the results were not identical in the two tests. The extent of the enhancement of prominence by source manipulations in our data depended on the location of focal syllable in the intonational phrase and on the length of postfocal material (the effect was stronger for WAY than for YEAR).
