How do we form phonemic categories? How is speech perception linked to the articulatory and acoustic production of speech? These are classic phonetic questions that are still controversially debated today.
I will present experimental and clinical phonetic data to approach these questions. Specifically, I will discuss (1) how the cognitive system is intricately linked to the speech production system based on the phonological voicing contrast, (2) how cross-linguistic differences in Romance vs. Germanic languages surface in perception compared to production, (3) how several acoustic cues of the speech signal are used with varying weights to form a robust phoneme identification and (4) how different anatomical and articulatory pattern shape the acoustic speech output in pathological speech for patients with glossectomy.
I conclude my talk with an excursion into audio-visual speech perception by presenting a phonetic experiment examining the effect of facial hair on speech intelligibility.
