What's this about?
Whodunnit is a Show HN game where you solve a murder mystery by *talking out loud* to AI-played suspects, interrogating them and catching them in contradictions. It's a fun, polished demo of real-time voice agents that maintain a consistent story.
What exactly is a "voice agent"?
A voice agent is an AI you interact with by speaking — it transcribes your speech, reasons about it, and replies in a generated voice, in near real time. The hard parts are low latency (so conversation feels natural) and memory/consistency (each suspect must stick to their alibi across the whole interrogation). Whodunnit turns exactly those hard parts into the gameplay.

- Genuinely fun — commenters found the interrogation loop engaging, a rare "AI demo I actually enjoyed" reaction.
- Latency and voice quality — discussion of how snappy the back-and-forth feels and which voice stack makes real-time interrogation work.
- Consistency is the trick — interest in how the suspects keep their stories straight (and whether you can break them with clever questioning), i.e. the memory problem made playable.
