The lab uses experiments to find out how the sounds of speech are actually heard.
AboutAbout the lab
How is speech heard?
The Liang Lab studies perceptual phonetics, using experiments to test how people hear the sounds of speech.
Based on listeners' responses, the lab examines how they distinguish Japanese pitch accent and how fast speech sounds to them.
It also looks at how hearing differs between native speakers of Japanese and learners of Japanese.
The lab also carries out analyses using a corpus of everyday conversation.
Key terms
- Perceptual phonetics
- The field that studies how listeners distinguish the sounds of spoken language

The lab investigates how the sounds of speech reach listeners, using listening experiments and analysis of speech data. It focuses on differences between native Japanese speakers and learners, and on differences by speaker gender and age group.
*Illustrative imagePerceived Speech Rate
Using a corpus of everyday conversation, the lab analyzed how speech rate varies with speaker gender, age group, and conversation format. It also examines how speaker gender affects the speech rate perceived by older listeners.
*Illustrative imageDistinguishing Japanese Pitch Accent
The lab uses identification experiments to study how listeners distinguish Japanese pitch accent, in which pitch rises and falls within a word. It has also shown how experience of studying Japanese affects listeners' ability to distinguish accent patterns.
