OmniVoice Studio — Open-Source Voice Cloning and TTS Desktop App

Introduction

OmniVoice Studio provides local voice cloning, text-to-speech synthesis, dubbing, and dictation capabilities without sending audio data to third-party servers. It targets developers and content creators who need high-quality voice generation while retaining full control over their data.

What OmniVoice Studio Does

• Clones voices from short audio samples for personalized speech synthesis
• Generates speech in multiple languages with natural intonation
• Provides video dubbing with automatic lip-sync alignment
• Offers real-time dictation and transcription via local speech recognition
• Runs entirely on-device using local GPU acceleration

Architecture Overview

OmniVoice Studio is built as a Python desktop application with a web-based UI. It integrates multiple open-source TTS and ASR models, routing audio through a local inference pipeline. Voice cloning uses speaker embedding extraction paired with a multi-speaker synthesis model, while dubbing leverages forced alignment to match translated speech to video timing.

Self-Hosting & Configuration

• Requires Python 3.10+ and a CUDA-capable GPU for optimal performance
• Install dependencies via pip from the provided requirements file
• Configure model paths and output directories in the settings panel
• Supports Docker deployment for isolated environments
• GPU memory requirements vary by model; 8 GB VRAM is recommended

Key Features

• Privacy-first design with zero cloud dependency
• Multi-language TTS supporting dozens of languages
• Voice cloning from as little as 10 seconds of reference audio
• Built-in audio editor for post-processing generated speech
• Extensible architecture supporting custom model backends

Comparison with Similar Tools

• ElevenLabs — cloud-based with usage limits and subscription costs; OmniVoice runs locally for free
• Coqui TTS — library-focused without a desktop UI; OmniVoice provides an integrated application
• Bark — generates audio with music and effects but lacks voice cloning; OmniVoice specializes in cloning
• Fish Speech — strong multilingual TTS but no dubbing workflow; OmniVoice includes video dubbing
• Kokoro — lightweight 82M model with limited customization; OmniVoice supports multiple model backends

FAQ

Q: Does OmniVoice Studio require an internet connection? A: No. All processing happens locally on your machine once models are downloaded.

Q: What GPU is needed to run OmniVoice Studio? A: An NVIDIA GPU with at least 8 GB VRAM is recommended. CPU-only mode works but is significantly slower.

Q: Can I use cloned voices commercially? A: The software is open source, but you are responsible for complying with applicable laws regarding voice cloning and consent.

Q: Which audio formats are supported? A: WAV, MP3, FLAC, and OGG are supported for both input and output.
