Show HN: Voice driven murder mystery, Interview AI suspects with your voice

Hey HN! I'm thrilled to introduce a captivating project I've recently developed. When I first created this concept 2-3 years ago, the world of AI was rapidly advancing, but voice AI agents were still in their infancy. Although I was satisfied with the prototype at the time, I couldn't resist exploring the technology again. Many of you might find this interesting.

The core of the project involves speech-to-speech interviews powered by OpenAI's gpt-realtime-2.1 over WebRTC. However, due to the high cost of this model, I had to impose certain limitations. Conversations are linked to authenticated Clerk user IDs, and to prevent overspending, each session is restricted to a 30-minute time limit.

Each suspect has a unique tool they utilize when you make a direct accusation. This tool records the accused party and a precise list of the evidence you've presented. Subsequently, a separate gpt-5-mini judge evaluates whether the required evidence facts were accurately presented by you. Paraphrasing is acceptable, but vague suspicions and fishing are not.

The application is built using Next.js, MongoDB, and Clerk. I look forward to your feedback on whether the suspects hold up under a genuine interrogation. For more information, please visit the comments URL: https://news.ycombinator.com/item?id=49238851.
