Audio files are provided for a consonant-vowel syllable continuum that starts with the sound "bae", moves through "dae" and ends up at "gae". These syllables were produced using the Pattern Playback by hand-painting each of the carefully controlled formant patterns. In this continuum, the lower band of energy (the first formant) is the same for each syllable. The only thing that is changing is the second formant transition. The continuum consists of 13 items. The onset of the second formant transition is varied in equal frequency steps. The Pattern Playback provided an experimental tool that for the first time let researchers systematically control the important acoustic information in speech signals. In turn, these researchers could then also evaluate the perceptual consequences of these careful acoustic manipulations. In the example presented here we can see the importance of the second formant transition in determining the consonant identity.
