DEDUPEDWho it is forIndie game developer or narrator who needs a distinct character voice and has no actor
The problemWithout a recorded sample, there is no easy way to get a custom character voice.
The outcomeA usable generated voice that fits the character, produced locally.
What you need first
- macOS, Windows or Linux desktop (Intel Mac runs the UI only and needs a remote backend)
- NVIDIA GPU (CUDA) or Apple Silicon (Metal) recommended; CPU-only works but is slower and needs about 5 GB free disk
- Git, Node.js 22+, Bun and Rust/Cargo only if building from source
- Speech models are downloaded on demand through the app; no paid keys or accounts required
Steps
- Install the app and open the Voice design workspace.
- Describe the voice you want in plain words.
- Generate sample lines and adjust the description until it fits.
- Use the voice for your script in the generation workspace.
Prompt for your agent
With debpalash/VoiceStudio, design a voice matching <voice description> and generate <script line>. Check that the voice stays consistent across two different lines.
Caveat. Designed voices can drift between generations, so test consistency before committing a whole script.
