Voice In, Voice Out

Voice AI

Local APIs for automatic speech recognition and text-to-speech.
No cloud dependency, no per-minute costs — runs locally on any hardware.

Automatic Speech Recognition

The listening side of the stack. Real-time transcription, voice activity detection, and echo cancellation working together so your agent hears clearly and responds at exactly the right moment. Runs in push-to-talk or always-on mode.

Speech-to-Text

On-device transcription across 3+ languages. Runs on CPU with streaming partial results — no GPU, no cloud, no batch processing.

Voice Activity Detection

Knows when someone starts and stops talking. Precision endpointing so your agent responds at the right moment — not too early, not too late.

Acoustic Echo Cancellation

Filters out the agent’s own voice from the mic input in real time. Enables full-duplex conversation and natural interruption.

Text-to-Speech

Every voice you hear below was synthesized on a single CPU core. No GPU, no cloud, no API calls — just neural inference running directly on the device. The first word plays in under 100 milliseconds.

Hello there! I’m Hannah. The beauty of natural language lies in its ability to convey emotion and meaning through subtle variations in tone.
