Developers · CLI & Skills

Install EdgeSpeak CLI

The CLI includes its own local speech runtime, so you can transcribe audio and video or connect scripts, MCP, and agents without opening the desktop app.

Install from Terminal on macOS or Linux, or from PowerShell on Windows. CPU works out of the box; Linux detects supported NVIDIA GPUs automatically, while Windows offers CUDA as an opt-in install.

Agent Skills, same engine

EdgeSpeak Skills teach Claude Code, Cursor, and other Skills-capable agents to transcribe on-device through the CLI. Open source on GitHub.

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.

  1. Lattice on your device

    Lattice turns audio and video into transcripts on the computer in front of you.

  2. Review while listening

    The transcript follows playback, so correction happens in one workspace instead of across tools.

  3. 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.

LOCAL LM + VLM · 0.6B — 27B

Local language and vision, in the same EdgeSpeak runtime.

EdgeSpeak now ships Qwen and Gemma models from 0.6B to 27B. One model loads at a time and sleeps when idle.

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.

Audio, video, and transcripts in one workspacePlayback, timeline, transcript, export, recent files, and the active local model stay together, so you switch tools less and keep more context.

Workflows

Start with your speech workflow

Private transcription, desktop review, agent access, and local-versus-cloud guidance.

Private transcription

Keep source media on-device and generate the transcript locally.

Local audio and video transcription

Review with playback, then export text or subtitles.

AI agent transcription

Install the EdgeSpeak Skill and let agents call the local CLI.

Local transcription vs cloud APIs

Choose by media location, processing scale, and integration path.

Privacy

Local-first speech processing.

EdgeSpeak is designed so imported media and generated transcripts stay on your device unless you export, upload, or share them.

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.

Results keep moving

Export text or subtitles, or let another tool continue from the finished transcript.

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.

Local OpenAI-compatible endpointCLI / agents / automationEdgeSpeak Flash and Pro

Choose by workflow

Local software, cloud APIs, or a model you maintain

The right option depends on where media can go, how much workflow you want ready-made, and who should maintain the speech stack.
