Real-Time Game Captioning That Survives Voice Chat, Game Audio, and Custom Game Vocabulary
A hard-of-hearing software engineer posted on r/deaf about spending seven months building CaptionsRush because every existing captioning tool fell apart on game audio: in-game voice chat mixes with explosions, gamer slang and proper nouns get mangled, latency lags a half-second behind the action, and standard browser/OS captions don't capture VOIP audio. The post hit 115 upvotes and pulled out a four-year competitor (xrai.glass) plus other Deaf devs working on the same problem. Multiple builders converging on the same niche is the strongest signal there is — the existing Big Tech accessibility solutions visibly aren't enough.
The wedge here is custom game vocabulary. ASR drift on "Reload Battle Pass" or "Jett ult" or "frag out" is what makes general captioners feel broken to gamers. Ship a per-game lexicon pack (Valorant, Apex, Arc Raiders) on day one, free tier forever — the HoH community is small and tight, they will roast a paywall and they will evangelize a product that respects them. Monetize via streamer-side and esports-team accessibility compliance, not via the player.

Live captioning is a maturing market for meetings and streams. Live captioning of mixed game-and-voice-chat audio with low latency and custom-vocabulary support is its own subdiscipline that even the four-year veteran (xrai.glass) hasn't fully nailed. Multiple Deaf software engineers building competing tools is unusual — that's the loudest possible signal that the platform-level solutions remain inadequate.
