Installation

VoiceHub supports Python 3.10–3.12. Install it from source.

Create an environment

Choose your platform.

python3 -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip

python3 -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip

py -3.12 -m venv .venv
.venv\Scripts\Activate.ps1
python -m pip install --upgrade pip

Install

Choose the correct PyTorch build for your hardware, then install VoiceHub from GitHub:

python -m pip install "voicehub @ git+https://github.com/kadirnar/voicehub.git@main"

Add training dependencies only when needed:

python -m pip install "voicehub[training] @ git+https://github.com/kadirnar/voicehub.git@main"

Editable checkout

Use an editable checkout when changing the library:

git clone https://github.com/kadirnar/voicehub.git
cd voicehub
python -m pip install -e ".[test,training,docs]"

Verify

Check the installation without downloading a checkpoint:

python -c "import voicehub; print(voicehub.__version__, len(voicehub.list_model_specs()))"

Check the accelerator separately:

python -c "import torch; print(torch.__version__, torch.cuda.is_available())"

Cache and offline mode

Pass cache_dir to isolate model files. Set local_files_only=True after the required checkpoint and processor assets have been downloaded.

from voicehub import AutoConfig

config = AutoConfig.from_pretrained(
    "parler-tts/parler-tts-mini-v1",
    model_type="parlertts",
    cache_dir=".cache/voicehub",
    local_files_only=True,
)
print(config.model_type)

Choose your platform when starting an offline process.
