So for the past 24 hours, ive been working on a personal project that integrates real time speech recognition with rblx using a custom python companion app. This is not a public gameplay feature, its a developer side tool or exclusive feature to me i built to help test and direct my game’s dispatch/callout systems more realistically
The system lets me use push‑to‑talk voice commands (like for ex: “151, send EMS”) and have Roblox respond with
- callouts
- NPC interactions
- tow/EMS/coroner requests
- voicelines
- radio static
- background checks
- Code 4 clearing
- and more
How It Works
The structure is simple but works well

Dispatch System
The Python app handles:
- speech to text
- callsign detection
- session mode (e.g., “151.” , “Go ahead.” , “Send EMS.”)
- push to talk
- window focus detection
- threading mic locks
- command parsing
- ngrok tunneling
Roblox handles:
- command interpretation
- callout routing
- nearest NPC/vehicle detection
- voicelines
- dispatch responses
- background checks
- callout clearing

Features
- Real‑time voice command recognition
- Callsign‑based activation
- Session mode for radio flow
- Full dispatch voiceline system
- Tow/EMS/Coroner integration
- Callout generator support
- Code 4 + scene clearing
- Background check system
- Mic static + radio effects
- Focus‑aware push‑to‑talk
- Thread‑safe audio pipeline
- Works in Studio and live Roblox (via ngrok)
Why I Built This
This is a exclusive feature, not a public feature, rblx does not allow games to access a players mics, so this system is strictly a developer side tool/exclusive feature for testing and directing callouts in my LawLine game
