Speech Prosody 2010
Chicago, IL, USA
The present study investigates the boundaries of speech and song from an acoustic-perceptual perspective. Using the speech-to-song illusion as a method, we tested rhythmic and tonal hypotheses to find out whether acoustic characteristics can cue the perceptual classification of a sentence by German listeners as sung or spoken. First, our results show that, despite individual differences, the speech-to-song illusion is a robust perceptual phenomenon comparable to those known in visual perception. Second, the experiment revealed that acoustic parameters especially tonal structure facilitate the perceptual shift from speech to song pointing to an acoustically guided decoding strategy for speech- vs. song-like signals.
