What You Can Do

Three core capabilities built for creators and developers who need control

Voice Cloning

Clone any voice with just seconds of audio. Train custom models instantly and deploy locally or on your own infrastructure. Perfect for personalized content, accessibility applications, and multilingual projects without expensive voice talent.

Video Dubbing

Translate and dub videos while preserving emotion, timing, and speaker identity. Automatically sync dubbed audio to video for seamless multilingual content creation. No expensive studios, no manual timing adjustments.

Speech Transcription

Convert audio to text with high accuracy across 50+ languages. Process files locally for complete privacy and security. Integrate through REST APIs or batch processing for enterprise workflows.

How It Works

Four steps from installation to deployment

Install

Prepare

Gather your source voice clips or video files. VoiceStudio handles preprocessing automatically and intelligently.

Generate

Run synthesis or dubbing locally with full control over quality, speed, and resource allocation. Monitor progress in real time.

Deploy

Export audio or video and integrate into your applications. Containerized with Docker for cloud or on-premise deployment.

Frequently Asked Questions

Can I use VoiceStudio commercially?

Yes. The Community edition is open-source under MIT license, suitable for most commercial projects. For companies wanting commercial support and no open-source obligations, upgrade to Professional or Enterprise.

How much audio do I need to clone a voice?

As little as 5-10 seconds of clear audio in a single language works well. More audio (30+ seconds) improves quality and naturalness of the cloned voice. Synthetic background noise is automatically filtered.

What hardware do I need?

VoiceStudio runs on CPU, but GPU acceleration (NVIDIA/AMD) speeds up processing 5-10x. Minimum: 4GB RAM. Recommended: 8GB+ RAM and a modern GPU for production workflows.

Can I integrate it with my application?

Yes. VoiceStudio exposes REST APIs for voice synthesis, dubbing, and transcription. Docker support makes deployment straightforward on AWS, GCP, Azure, or your own infrastructure.

Is my data private?

Completely. All processing happens locally on your machine by default. No audio is sent to external servers unless you explicitly choose cloud deployment for your own infrastructure.

How do I get support?

Community members get GitHub issues and discussion forums. Professional subscribers get priority email support. Enterprise clients get dedicated support engineers with SLA-backed response times.

Want VoiceStudio built out, or handed over?
