Performative Vocal Synthesis for Foreign Language Intonation Practice

Abstract

We evaluate a tablet-based interface where users gesturally control the pitch of a pre-recorded utterance by drawing curves on the touchscreen. 24 subjects (12 French learners, 12 British controls) imitated English phrases with their voice and the interface. Results of an acoustic analysis and expert perceptive evaluation showed that learners' gestural imitations yielded more accurate results than vocal imitations of the fall-rise intonation pattern typically difcult for francophones, suggesting that PVS can help learners produce intonation patterns beyond the capabilities of their natural voice. CCS CONCEPTS • Human-centered computing → Empirical studies in interaction design; Gestural input; Sound-based input / output; Touch screens.
