Acoustically induced bifurcation. Downward pitch glide for vowel āiā using setup 1: (a) normalized microphone signal, (b) microphone spectrogram, (c) normalized accelerometer signal, and (d) accelerometer spectrogram. Upper arrows bound the register transition section to be further analyzed in Fig. 7. Lower arrows bound a less periodic region in the signals after the bifurcation point.
