KazakhTTS-OmniVoice

KazakhTTS-OmniVoice is a Kazakh text-to-speech model fine-tuned from `k2-fsa/OmniVoice`.

The model is designed for natural Kazakh speech synthesis and supports controllable voice attributes through OmniVoice's voice design interface, including gender, age-style prompts, and pitch-style prompts.

This checkpoint was fine-tuned specifically for the Kazakh language using a mixture of real Kazakh TTS data and synthetic controlled voice-design data.

Training Data

KazakhTTS-OmniVoice was fine-tuned using a mixture of real Kazakh speech data and synthetic controlled voice-design data.

The main real speech component comes from ISSAI_KazakhTTS2, a Kazakh text-to-speech dataset used to improve pronunciation, rhythm, and naturalness for Kazakh speech synthesis.

The synthetic component was generated to improve controllability for speaker attributes such as gender, age-style prompts, and pitch-style prompts.

Approximate fine-tuning mixture:

—56% real KazakhTTS2 data
—44% synthetic controlled data

Synthetic controlled dataset:

—10,800 generated Kazakh samples
—18 control categories
—600 samples per category
—Synthetic repeat during training: 13

The synthetic data was generated using a small number of stable reference voices per category, with many Kazakh target texts per voice. This was done to reduce speaker memorization while preserving consistent control behavior.

The original KazakhTTS2 dataset is not included in this repository. This repository only contains the fine-tuned model checkpoint and example audio generated by the model.

Audio Examples

Usage

This model is an OmniVoice checkpoint and should be used with the omnivoice Python library.

Install dependencies:

bash

pip install omnivoice soundfile torch

Python API

python

from omnivoice import OmniVoice
import soundfile as sf
import torch

model = OmniVoice.from_pretrained(
    "shyngys879/KazakhTTS-OmniVoice",
    device_map="cuda:0",
    dtype=torch.float16,
)

text = "Бүгін біз жаңа қазақша дауыс моделін тексеріп жатырмыз. Дауыс табиғи, анық және түсінікті болуы керек."

audio = model.generate(
    text=text,
    language="Kazakh",
)

sf.write("kazakh_tts_output.wav", audio[0], 24000)

Voice Cloning Example

python

from omnivoice import OmniVoice
import soundfile as sf
import torch

model = OmniVoice.from_pretrained(
    "shyngys879/KazakhTTS-OmniVoice",
    device_map="cuda:0",
    dtype=torch.float16,
)

audio = model.generate(
    text="Бүгін біз қазақша дауыс синтезін тексеріп жатырмыз.",
    language="Kazakh",
    ref_audio="reference.wav",
    ref_text="Бұл reference аудиода айтылған мәтін.",
)

sf.write("kazakh_cloned_voice.wav", audio[0], 24000)

Download Locally

python

from huggingface_hub import snapshot_download

model_dir = snapshot_download(
    repo_id="shyngys879/KazakhTTS-OmniVoice",
    local_dir="KazakhTTS-OmniVoice",
)

print(model_dir)
