Idiosyncrasies in the auditory (top) and motor (bottom) models of speech perception.

Each plot displays prototypes for the auditory or motor decoder, for each of the twelve Learning Agents and for each of the seven learned vowels. Vowel prototypes are defined as the mean of the distributions P(S | OL) (auditory model) or P(S | OS) (motor model) for a given Agent and a given vowel o. In each plot, prototypes for each vowel and each agent are shown as colored dots in the first two formant acoustic space (F1, F2) (in Barks), following the same presentation as in Fig 4.
