An approach to modelling speech perception is proposed that integrates acoustic-phonetic and psycholinguists knowledge. The approach acknowledges the value of models of acoustic invariance and trading relations, usually considered to be in opposition to each other, by suggesting that both types of perception occur, but operate in different circumstances. It acknowledges the versatility of the human listener, and the robustness of the speech signal.
