KeenASR SDK brings high-accuracy, kid-optimized automatic speech recognition directly to your mobile app or device, no internet connection required.

Designed for EdTech and children's interactive experiences, KeenASR helps you build engaging voice interactions that work anywhere, respond instantly, and keep every child’s data on the device.

Built for Privacy, Speed, and Children’s Voices

Private by Design

All processing happens locally, so children’s speech never leaves the device, ensuring COPPA compliance and removing the need for backend scaling.

Instant, reliable results.

On-device recognition provides real-time feedback and works offline, keeping apps responsive in classrooms, at home, and on the go.

Optimized for Children's Voices & Real-World Environments

Our acoustic models are trained specifically for young voices and noisy environments, giving you accuracy that general-purpose ASR systems often miss.

Made for Learning & Interactive Play

KeenASR powers a wide range of kids’ experiences. It supports phonics, vocabulary, numeracy, and early reading practice, as well as pronunciation and second-language learning. Speech therapy exercises can run fully offline. For entertainment, it handles interactive videos, fictional languages, and simple voice-driven navigation.

Developer Friendly by Design

The SDK provides native support for iOS and Android, and brings the same engine to the browser via a lightweight JavaScript library. On top of that, Unity integration and cloud-based tools help teams prototype, test, and refine voice experiences quickly using a clean, easy-to-use API.You can dynamically define what the recognizer listens for, and deploy the same engine consistently across mobile apps, Chromebooks, and browsers.
