VoiceStudio: The 82k-Star Open-Source ElevenLabs Alternative That Runs Fully Local

Description and use

VoiceStudio is a fully local, open‑source alternative to ElevenLabs, offering 646‑language TTS, STT, and dubbing with multiple engines, offline operation, and per‑segment caching.

Problem

Users of ElevenLabs face per-character pricing, rate limits, and data egress concerns.

Outcome

VoiceStudio replaces ElevenLabs with a zero-cost, fully local workflow, supporting 646 languages, multiple TTS engines, and offline transcription and translation.

Workflow

• Install VoiceStudio via one-command script or download
• Select a mode (Podcast Editor, Text-to-Voice, Transcribe, Dub)
• Choose or upload a voice (reference clip 10–30s for cloning)
• Enter or drop text/audio
• Generate audio (models download on first use, then cached)
• Export or use local REST/MCP API

Evidence

VoiceStudio (debpalash/VoiceStudio, 82.2k ⭐) is exactly that. It's an Electron desktop app backed by a local Python backend that bundles multiple state-of-the-art open TTS engines.

The per-segment cache is a subtle but critical detail: re-running the same text + voice + config uses the cached WAV (models are deterministic).

Source

Voice cloning (30 seconds): Open Voice Cloning tab, Choose a voice or add a clean reference recording (10–30s), Enter your text, Generate — model downloads on first use, then cached

Source

The application is AGPL-3.0 (covers commercial use under its conditions). Model weights, tokenizers, voices, and generated-output conditions are separate — a paid app license does not grant those rights.
