Text-to-Speech for Ukrainian

High-fidelity speech synthesis for Ukrainian using modern neural networks.

Statuses

Demo

Check out our demo on Hugging Face space or just listen to samples here.

Features

• Multi-speaker model: 2 female (Tetiana, Lada) + 1 male (Mykyta) voices;
• Fine-grained control over speech parameters, including duration, fundamental frequency (F0), and energy;
• High-fidelity speech generation using the RAD-TTS++ acoustic model;
• Fast vocoding using Vocos;
• Synthesizes long sentences effectively;
• Supports a sampling rate of 44.1 kHz;
• Tested on Linux environments and Windows/WSL;
• Python API (requires Python 3.9 or later);
• CUDA-enabled for GPU acceleration.

Installation

# Install from PyPI
pip install tts-uk

# OR, for the latest development version:
pip install git+https://github.com/egorsmkv/tts_uk

# OR, use git and local setup
git clone https://github.com/egorsmkv/tts_uk
cd tts_uk
uv sync # uv will handle the virtual environment

Read uv's installation section.

Also, you can download the repository as a ZIP archive.

Getting started

Code example:

import torchaudio

from tts_uk.inference import synthesis

sampling_rate = 44_100

# Perform the synthesis, `synthesis` function returns:
# - mels: Mel spectrograms of the generated audio.
# - wave: The synthesized waveform by a Vocoder as a PyTorch tensor.
# - stats: A dictionary containing synthesis statistics (processing time, duration, speech rate, etc).
mels, wave, stats = synthesis(
    text="Ви можете протестувати синтез мовлення українською мовою. Просто введіть текст, який ви хочете прослухати.",
    voice="tetiana",  # tetiana, mykyta, lada
    n_takes=1,
    use_latest_take=False,
    token_dur_scaling=1,
    f0_mean=0,
    f0_std=0,
    energy_mean=0,
    energy_std=0,
    sigma_decoder=0.8,
    sigma_token_duration=0.666,
    sigma_f0=1,
    sigma_energy=1,
)

print(stats)

# Save the generated audio to a WAV file.
torchaudio.save("audio.wav", wave.cpu(), sampling_rate, encoding="PCM_S")

Use these Google colabs:

• CPU inference
• GPU inference on T4 card (long document to synthesize)

Or run synthesis in a terminal:

uv run example.py

If you need to synthesize articles we recommend consider wtpsplit.
