Local-first workflow
Transcripts, reference voices, and generated audio stay on your machine.
Local voice generation, composed
Voice cloning.
Local by default.
A terminal-native CLI that turns long-form transcripts into speech with reusable voices, rich diagnostics, and a workflow that stays on your machine.

Everything the generation loop needs.
Nothing it doesn’t.
LLMVoice keeps the surface small while making the local workflow legible, resilient, and pleasant to use.
Reference voice cloning
Add and reuse named voices from a clean reference WAV in one command.
Long-form ready
Chunking, pauses, merging, and encoding are handled as one reliable pipeline.
Clean CLI UX
Readable output, purposeful progress, and errors that tell you what to fix.
GPU or CPU
Use CUDA acceleration when available, with a practical CPU fallback.
Diagnostics built in
Doctor, dry-run, and debug modes make the local environment inspectable.
Open architecture
MIT-licensed source with a focused Python CLI surface and no service layer.
Safe output handling
Explicit overwrite behavior, disk checks, and predictable output paths.
Configurable by design
Set voice, language, device, speed, chunk size, and pause defaults.
Four deliberate steps
Reference in. Finished audio out.
01
Add a voice
Create a named local voice from clean reference audio.
02
Feed a transcript
Point the CLI at a text file, short or long.
03
Generate locally
XTTS-v2 runs through CUDA or a CPU fallback.
04
Get your MP3
Chunks merge into one clean, ready-to-play file.
Terminal-native
A workflow you can read at a glance.
Inspect the machine, register a voice, set a default, then generate. Each command does one thing and reports exactly what happened.

Your voice never needs to leave the room.
LLMVoice is a local CLI, not a hosted service. There is no account, ingestion pipeline, or remote inference layer between your files and your output.
No cloud APIs
No telemetry

LLMVoice source code is MIT licensed. XTTS-v2 model weights are licensed separately under the Coqui Public Model License (CPML); the MIT license does not grant commercial rights to model usage. LLMVoice is positioned for local, non-commercial use unless you hold the appropriate model rights.
