Summary

A new survey systematically reviews and categorizes automated presentation coaching systems, which integrate computer-assisted pronunciation training (CAPT), prosody modeling, and speech synthesis. The work covers pronunciation tutors, fluency and prosody coaches, multimodal trainers, and conference Q&A practice tools. It introduces a five-dimensional task taxonomy encompassing segmental pronunciation, lexical stress, suprasegmental prosody, pacing, and content faithfulness, mapping existing systems to identify coverage gaps. The survey also details core technical methods, including TTS-based exemplar generation and diagnostic approaches for pronunciation, prosody, and fluency assessment. Key open challenges highlighted are the scarcity of annotated presentation corpora, achieving accent-fair feedback across diverse L1 backgrounds, and delivering low-latency diagnostics for real-time rehearsal.

Key takeaway

For NLP Engineers developing automated presentation coaching tools, this survey highlights critical areas for innovation. You should prioritize creating accent-fair feedback mechanisms and developing low-latency diagnostic systems for real-time rehearsal. Addressing the scarcity of annotated presentation corpora is also crucial to advance system capabilities and ensure robust performance across diverse user backgrounds.
