On-Device Speech Recognition for Gaming

Add immersive, real-time voice interactions to your games, no internet required

KeenASR SDK brings high-accuracy speech recognition directly into your game, running natively on iOS, Android, web (JS), and Linux. Designed for real-time interactive experiences, it lets players use their voice as a natural input, without cloud round-trips or connectivity requirements.

Whether players are issuing commands, speaking to characters, or reading aloud, KeenASR provides instant, accurate recognition that keeps pace with gameplay.

Trusted by leading game studios and interactive entertainment companies to deliver responsive voice experiences across platforms.

Built for Real-Time Gameplay

Cloud-based speech recognition introduces latency that breaks immersion. By the time a cloud service returns a result, the moment has passed. KeenASR processes speech locally, delivering results instantly so voice input feels as responsive as a button press. Players stay in the game.

Why On-Device Instead of Cloud?

Game developers evaluating speech recognition often compare on-device and cloud-based options. Here's how KeenASR compares:

	KeenASR (On-Device)	Cloud ASR
Response time	Instant (on-device)	Network latency + processing
Works offline	✓ Yes	✗ No
COPPA/GDPR compliant	✓ By design	Requires configuration
Custom vocabulary	✓ Full support (fictional languages, game terms)	Limited or complex setup
Per-request cost	None (annual license)	Pay per API call

Low Latency, Private, and Always Available

Real-time performance for gameplay.

On-device processing delivers recognition results instantly, with no network latency. Voice input feels as responsive as a button press, keeping players immersed.

Private by design.

All audio is processed locally. No speech data leaves the device, making it straightforward to meet COPPA, GDPR, and platform privacy requirements.

Works offline, everywhere.

Players on planes, in rural areas, or simply without Wi-Fi get the same voice experience. No backend scaling needed for usage spikes at launch or during events.

Built for Interactive Entertainment

KeenASR powers a wide range of gaming experiences:

• Voice commands: Navigation, menus, and in-game actions
• Character interaction: Dialogue, conversation, and NPC communication
• Fictional languages: Klingon, Na'vi, Elvish, or your own invented vocabulary
• Interactive storytelling: Read-along games and narrative experiences
• Voice-driven puzzles: Challenges that respond to spoken input
• Interactive video: Voice-controlled media experiences

Native Unity Integration

The KeenASR Unity plugin lets you build cross-platform voice-enabled games from a single codebase, targeting iOS and Android with the same engine. The plugin provides a clean C# API that lets you dynamically define what the recognizer listens for at any point during gameplay.

Developer-Friendly, Cross-Platform

Beyond Unity, the SDK provides native support for iOS and Android, and extends to the browser via a lightweight JavaScript library. Cloud-based tools help teams prototype, test, and refine voice experiences quickly.
