This game puts you in the role of a detective, interrogating an AI suspect using your actual voice — not clicking through dialogue options like a typical game. The standout feature is that the AI responds in real-time to whatever questions you actually ask, so no two playthroughs feel the same. It genuinely feels like playing a detective in a movie. One caveat: this is a Show HN project, still in an experimental stage. Voice quality and AI accuracy may not be as polished as a fully-built game. Best played with headphones in a quiet room so voice recognition works properly.
This genre is interesting because it pairs voice AI with interactive storytelling — something still fairly new in the indie game scene. Anyone looking to try something different from the usual detective game formula will probably find this angle fun.
What does real-voice interrogation actually look like
The interface is very simple, no flashy 3D graphics — it centers on a suspect’s profile page with a mic button in the middle of the screen. Hold it down and just speak your question, no typing required.
During the conversation, a transcript appears in real-time on both sides — your questions and the AI’s answers — making it easy to scroll back and gather clues.
The overall atmosphere leans classic noir detective: dark tones, white text, giving the feel of actually sitting in an interrogation room rather than a plain chat window.
What stands out is that the UI isn’t cluttered — it’s focused entirely on the conversation, which suits anyone wanting to try a full voice-interaction experience.
Why detective games I’ve played before felt like reading a script
The dialogue-tree detective games I’ve played in the past have one problem: questions are limited to 3-4 pre-set options to click on, not anything you actually want to ask.
When you hit a dead end in the story, it often feels like you’re mashing buttons to find the “right” answer rather than actually investigating. The tension of an “interrogation” fades because you already know the options are limited.
That’s exactly why this Show HN project is interesting — it shifts from “selecting a question” to “speaking your own question out loud,” with the AI suspect responding live, with no fixed script blocking the way. It addresses the staleness problem of traditional dialogue trees head-on.
Where does this project sit in the AI-driven gaming trend
The idea of “talking to an NPC with your real voice” isn’t new at an industry level — big studios have been experimenting with LLM-driven NPCs for a while, but most of that is still in closed demos, not playable to the public.
What sets this project apart is that it’s an indie/side project posted directly on Show HN, open for anyone to try. It sits somewhere between old-school interactive fiction (text-based, choice-driven) and a detective game using voice input plus a live-responding LLM.
The selling point is the full stack: speech-to-text captures your question → an LLM processes it in character as the suspect → text-to-speech reads back the response as audio, all in real time. It’s essentially assembling existing market components into a reasonably polished game.
There’s no clear info on whether it’ll grow into a full product or stay a demo — but as a proof-of-concept, it hits the mark.
Comparing to traditional multiple-choice interrogation games
In old-school choice-based detective games, you pick questions from a pre-written list the designers prepared in advance, so answers stay locked within that pre-scripted frame.
Voice-driven mystery flips this — you can ask anything with your real voice, and the AI suspect responds live with no fixed script. The flexibility is on a whole different level.
But the trade-off is accuracy — a multiple-choice system has a 100% known outcome because it’s pre-determined, while a live-responding LLM risks hallucinating or breaking character. For a game where the murder plot needs to stay airtight, that risk matters a lot.
| Factor | Traditional Choice-Based Game | Voice-driven AI Interview |
|---|---|---|
| Question flexibility | Limited to a preset list | Ask anything, by voice |
| Response realism | On-script, never breaks character | Natural, but risk of hallucination |
| Plot accuracy | Tight, fully controlled | Harder to control, needs guardrails |
This Show HN project has no script to click through — you speak into the mic, and the AI suspect answers live based on its assigned personality. That’s what sets it apart from typical choice-based detective games.
Try playing detective and asking a layered question (“Where were you when it happened… and why did a witness say they saw you in the kitchen?”) — the AI has to handle it in real-time, not just pull a canned answer. If your tone gets pressuring or you press the same point repeatedly, some suspects start contradicting what they said earlier. That’s your opening to catch them in a lie.
The scariest part is when you press a weak point and the AI tries to cover it up instead of admitting it — it genuinely sounds like a real person lying. Once you’ve interviewed everyone, you piece the case together yourself; the game doesn’t hand you the answer, you have to assemble it from the full conversation.
Comparing to other AI detective/interrogation games out there right now
This genre isn’t a one-off — but most similar entries seen on Show HN or itch.io are still typing questions into a chatbot playing a character, not speaking with a real voice like this.
The main difference is input — this project uses direct voice conversation with the interrogation AI, so pressure in your tone, pacing, or repeated questions genuinely affect the answers, something a typed chatbot struggles to replicate.
| Factor | This Project (Voice Interrogation) | Typed Chatbot-style AI NPC Games |
|---|---|---|
| Communication format | Real voice conversation | Typed text |
| Naturalness of dialogue | Can catch tells from tone/pacing | Judged purely from text answers |
| Accessibility | Needs a mic/voice-capable browser | Easy access, type from anywhere |
Put simply, it’s a trade-off between convenience and realism — if you want it to feel like a real interrogation, voice is the way to go.
Pros and cons after actually playing it
On the plus side, the novelty factor is huge — being able to “speak” questions to a suspect instead of typing makes it feel like you’re actually in an interrogation room, and the AI throws smart questions back rather than just reciting lines, adapting to the angle you’re pushing.
The clear downside is that speech-to-text still stumbles on non-standard accents — sometimes mistranscribing badly enough to throw the whole conversation off. The AI also loses context periodically, answering off-topic or contradicting itself. The latency while waiting for the AI to process your voice also breaks the flow of the interrogation, not as smooth as talking to a real person.
Pros
- +Realistic — genuinely feels like an interrogation through tone of voice
- +AI asks creative questions that adapt to the conversation
Cons
- −Speech-to-text still struggles with certain accents
- −AI periodically loses context + noticeable response delay
Is it really free to play, and what’s the trade-off
For a project like this, the main cost is speech-to-text API fees plus the cost of calling an LLM per question. The more people play, the faster the quota burns — so don’t be surprised if rate limits show up one day, or free play gets shut off entirely.
Another thing people often overlook: your voice gets recorded and sent off to a server for processing, separate from the game itself. Without a clear data-deletion policy, your voice recording could sit somewhere indefinitely.
As for time, each case takes a while to interrogate through, since you have to keep speaking/asking questions until you piece together enough clues — unlike typical mystery games with quick clickable choices.
Replay value remains to be seen — how many cases are actually available, since most Show HN prototypes usually ship with just a handful of sample cases to try.
Who is this game for, and who should skip it
A project like this isn’t for everyone — worth checking against yourself before downloading it.
If you’re into detective fiction, interactive fiction, or curious how far voice AI can go in a game — this is worth trying. Developers interested in prompt design and voice interfaces should also keep an eye on it, since it demonstrates a clear real-time interrogation pattern.
But if you’re impatient and can’t stand the AI answering slowly or going off-topic, this game might be painful, since you have to keep asking questions until you’ve gathered all the clues. And if you’re not comfortable speaking into a mic in front of others (say, at the office or in public), skip it for now — it’s better enjoyed alone.
Made for
- Fans of interactive fiction or mystery games looking to try something new
- Developers interested in voice AI and prompt design
Think twice
- Fans of typical clickable-choice mystery games may need to adjust
Skip this one
- Impatient players who can't tolerate slow/off-topic AI responses — try a choice-based mystery game instead
- Anyone not comfortable speaking into a mic in public — save it for playing alone
What’s more interesting than the game itself is how far this pattern could be pushed. Imagine other detective games shifting from dialogue trees to genuine spoken interviews, or negotiation sims where you have to read your counterpart’s tone in real-time.
The common thread is voice-first gameplay, turning “speaking” into a core mechanic rather than just flavor voice acting like most games. Players have to come up with their own questions, listen for tone, and catch tells — much closer to a real investigative experience than picking from pre-written options.
The current limitation is that the AI can be slow or drift off-topic sometimes, but the direction is clear: interrogation, negotiation, and even dating sim genres will keep moving toward voice as voice AI latency keeps dropping.
