The Interplay of Speech Perception and Phonology: Experimental Evidence from Turkish

This study supports claims of a relationship between speech perception and phonology with evidence from a crosslinguistic perception experiment involving /h/ deletion in Turkish. Turkish /h/ is often deleted in fast speech, but only in a specific set of segmental contexts which defy traditional explanation. It is shown that /h/ deletes in environments where lower perceptibility is predicted. The results of the perception experiment verify these predictions and further show that language background has a significant impact on speech perception. Finally, this perceptual account of Turkish /h/ deletion points to an empirical means of testing the conflicting hypotheses that perception is active in the synchronic grammar or that its influence is limited to diachrony.
