Fast on-device transcription

Import audio or video and transcribe it locally with high accuracy

Drop in audio or video. EdgeSpeak handles transcription, timeline alignment, and transcript generation on this computer; when downstream tools need to continue, they can read the result from the local gateway.

Lattice on your device
Lattice turns audio and video into transcripts on the computer in front of you.
Review while listening
The transcript follows playback, so correction happens in one workspace instead of across tools.
Results keep moving
Export text or subtitles, or let another tool continue from the finished transcript.

Dedicated on-device model

Lattice-2, built for the desktop

Lattice-2 is compressed and optimized for on-device inference, so an everyday computer can transcribe audio and video efficiently.

On-device compression and inference tuning

The speech AI model is shaped for desktop execution, reducing wait time while local transcription avoids external service dependencies.

Flash / Pro model pairing

Flash is tuned for everyday audio and video transcription. Pro targets harder audio, more complex accents, and a higher accuracy ceiling while using more local resources.

Built into developer workflows

Lattice-2 supports 40+ languages, multiple English accents, and Chinese dialects; the same local engine is available to CLI tools, agents, and automation through the gateway.

Real desktop app

EdgeSpeak runs right on your computer

Import audio or video, choose a local model, and export the result. For automation, hand work to CLI tools or agents through the local gateway.

Local speech gateway

Let agents call EdgeSpeak directly

EdgeSpeak provides a local, OpenAI-compatible speech API, so CLI tools, agents, and automations can transcribe on the same computer. It is not another cloud. It is your computer's speech gateway.
