Abstract

The neural representation of speech parameters was investigated in the higher parts of the audi-tory pathway of a guinea pig. Single unit re-sponses were recorded to the synthetic speech-like sound from an unanesthetized animal. The speech-like sound was produced by a bank of octave band-pass filters to the input of a train of pulses, following the "terminal analog" model of speech production. It was provided with a formant structure superimposed on the harmonic fine struc-ture of a voice pitch and the formant transition and the consonant-vowel combination were also simulated though not refined enough.
