Figure 1

Video stills and spectrograms of auditory stimuli A1 (corresponding to /aba/), A5 (ambiguous sound halfway between /aba/ and /ada/) and A9 (/ada/). The auditory continuum was created by manipulating the formant transition of F2. The first acoustic change that signals the difference between /b/ and /d/ occurred around 140 ms after sound onset in the transition of second formant (F2) of the initial vowel. The release of the consonant was at about 400 ms after sound onset. In the video, the difference between /aba/ and /ada/ became apparent at around 120 ms.
