01 / HOW IT WORKS

One conversation.
Two directions.

Polyglot-Audio runs two independent audio routes at once. One carries your translated voice out. The other brings their translated voice back.

Made for live audio

Small frames, bounded buffers, and independent routes keep conversations moving.

2×

Truly bidirectional

TX and RX use separate provider sessions, controls, devices, and failure handling.

No text detour

Only providers with direct streaming audio input and translated audio output qualify.

02 / MOBILE RECEIVER

POLYGLOT-RX · ANDROID

Translation that
travels with you.

Polyglot-RX listens through your phone microphone, sends live audio to a direct speech translation provider, and plays the translated voice through connected headphones.

03 / BUILT WITH BOUNDARIES

Your voice is not
our product.

The interface never processes audio. Credentials live in your operating system keychain. Polyglot-Audio does not log raw audio, transcripts, keys, or authorization headers.

Read the security model ↗

OS keychainSecrets stay outside plaintext config files.

Sanitized diagnosticsUseful counters, without audio or device identities.

Vendor-neutralChoose a compatible provider. The audio engine stays independent.

Auditable sourceInspect the Rust engine and every provider boundary.

04 / GET THE APPS

Choose your
side of the wire.

Choose full-duplex desktop routing or the focused Android receiver. Both are early-stage open-source projects distributed through their official GitHub Releases pages.
