The phonetics group at Penn emphasizes the interdisciplinary and experimental nature of phonetics in both teaching and research. The group is engaged in a wide range of research topics, including laboratory studies of speech production and perception, prosody modelling, phonetic patterns and variation in large speech corpora, integration of phonetics and speech technology, etc.

The lab developed P2TK, the Penn Phonetics Toolkit, a collection of Python scripts and other tools to facilitate speech research.

The lab hosts a weekly lunch meeting called Speech Talk (formerly Speech Lunch).

The Schwarz Lab uses eye tracking and other psycholinguistic methods to investigate phenomena relating to understanding natural language meaning in context.
