Abstract
Vowel transitions sound smooth even though the neural activity patterns (NAP) in the auditory nerve oscillate and glottal intervals change size in discrete steps. Temporal integration (TI) can be used to stabilize auditory images and to smooth transitions, but traditional TI mechanisms smear out timing details that we hear if the integration time is long enough to produce smooth motion in speech sounds. The problem can be solved by performing TI separately within NAP channels and triggering the TI to occur at times corresponding to the larger pulses in the channel. The triggering process converts the rapidly flowing NAP into a high‐resolution auditory image in which “what you see is what you hear.” Formants that are audible are visible and global phase changes that are not heard are removed. Video illustrations show that vowel transitions produce smooth motion that occurs at the same rate as the motion that is heard in the sound. The auditory model requires about 50 MFLOPS for real‐time operation, which m...
