2010, a speech oddity: Phonetic transcription of reversed speech

By François Pellegrino, Emmanuel Ferragne and Fanny Meunier

Abstract

International audienceTime reversal is often used in experimental studies on language perception and understanding, but little is known on its precise impact on speech sounds. Strikingly, some studies consider reversed speech chunks as “speech” stimuli lacking lexical information while others use them as “non speech” control conditions. The phonetic perception of reversed speech has not been thoroughly studied so far, and only impressionistic evaluation has been proposed. To fill this gap, we give here the results of a phonetic transcription task of time-reversed French pseudo-words by 4 expert phoneticians. Results show that for most phonemes (except unvoiced stops), several phonetic features are preserved by time reversal, leading to rather accurate transcriptions of reversed words. Other phenomena are also investigated, such as the emergence of epenthetic segments, and discussed with insight from the neurocognitive bases of the perception of time-varying sounds
