Athena (AI Voice Coach for Thinking, Speaking, and Pitching)
Built at OpenAI Voice Hack Night · May 27, 2026 · San Francisco, CA

We as humans struggle to practice a technical presentation or product pitch by ourselves or find a human who listens carefully and gives actionable feedback. We built a real-time AI voice coach using Codex and the OpenAI Realtime API that listens during live practice sessions and provides feedback in voice or text to help identify gaps and improve your craft. The GPT model can respond when explicitly asked or proactively detect hesitation, pauses, or confusion in your voice. Potential use cases include product pitches, complex technical presentations, and sales calls.
