Research Dr. Harnsberger’s research concerns the perception and learning of the linguistic and indexical properties of speech, particularly from a cross-linguistic and/or crosscultural perspective. The linguistic properties of speech include all aspects of the speech signal that serve to communicate meaning through language (speech sounds, syllables, words, phrases, utterances). The indexical properties of speech include aspects of the speech signal that provide information about the speaker (e.g., his/her age, regional or social dialect, gender, vocal tract shape/size) or about the audience he/she is addressing (e.g., speaking rate, speaking style). Currently, several projects are underway at the Speech Perception Laboratory, including: 1. Modeling the perception of non-native speech sounds 2. Perceptual correlates to vocal aging 3. Perceptual category access in bilingual listeners 4. Short-term memory effects in cross-language speech perception 5. The effects of stress and deception on voice 6. Acoustic and perceptual correlates of ethanol intoxication in speech 7. Acoustic/auditory similarity metrics
