VoiceStar: Robust, Duration-Controllable TTS that can Extrapolate

VoiceStar: Robust, Duration-Controllable TTS that can Extrapolate

VoiceStar is a robust, duration-controllable TTS model with support for test-time extrapolation, meaning it can generate speech longer than the duration it was trained on.

Features

• Duration control: Specify the duration of the generated speech.
• Zero-shot voice cloning: Clone any voice with a short reference audio clip (demo video).

Coming soon: research paper (ETA: 7 April 2025 - 14 April 2025)

Quick Start

Install

pip install voicestar

Make sure you also have espeak-ng installed.

Note: If you run into issues installing VoiceStar with uv, try installing it with pip instead.

Usage

Basic usage:

voicestar --reference-speech "./demo/5895_34622_000026_000002.wav" --target-text "I cannot believe that the same model can also do text to speech synthesis too! And you know what? this audio is 8 seconds long." --target-duration 8

Please refer to the CLI and Python API documentation below for more advanced usage.

Training

Please refer to the training docs for more information.

Inference

CLI

voicestar --reference-speech "./demo/5895_34622_000026_000002.wav" --target-text "I cannot believe that the same model can also do text to speech synthesis too!"

Python API

from voicestar import VoiceStar

# Initialize the model
model = VoiceStar()

# Generate speech from text
audio = model.generate("I cannot believe that the same model can also do text to speech synthesis too!")
audio.save("output.wav")
