Speech Processing Lab

About the Facility

The goal of research in the lab is to explore the cognitive processes involved in mapping speech sounds onto linguistic representations. To that end, our research has focused on the perception of lexical tones in Mandarin Chinese. Lexical tones are prosodic features of speech that can be used for word distinctions in tone languages. For example, the syllable ma with a high tone means “mother”, but ma with a low tone means “horse” instead. Given that the majority of the world’s languages are tone languages, a complete theory of speech communication requires understanding these “suprasegmental” aspects of speech.
