This is a experimental repository containing currently `1` model operating at 32-KHz (Effective 16-KHz) sample rate.

[Overview]

This project's intention is to create both higher quality Piper-TTS (Vits family) models, and partially show effects or lack there of, during distillation from another voice mode.

Due to the training dataset being generated by another diffusion-based TTS model, and because of the inherent architecture of VITS, it's expected to encounter, out of ordinary quantization artifacts or misalignment in pronunciations during inferencing.

Currently available voices are:

en_US-mei-high-onnx

There is a checkpoint available for continuous training:

epoch=699-step=200120.ckpt

[Inference Guide]

Inferencing is really simple. Follow the steps below.

This is tested working within a Python==3.14 conda environment.

NOTE: You may change the noise_scale and noise_w to adjust variations for your workload. Or reference to PIPER_REPO. Furthermore, the best settings found are noise_scale : 0.75 and noise_w_scale : 0.75

1. Install the piper-tts package using pip.

pip install piper-tts

2. Download the model file from above, alongside the corresponding .json file.

3. Put them both into the same folder.

4. Create a .py with your desired name and add the below code.

python

import wave
from piper import PiperVoice

voice = PiperVoice.load("/path/to/YOUR_DOWNLOADED_MODEL.onnx")
with wave.open("test.wav", "wb") as wav_file:
    voice.synthesize_wav("Welcome to the world of speech synthesis!", wav_file)

Remember to change YOUR_DOWNLOAD_MODEL.onnxto the actual one.

[Training Details]

This model is trained on combination of CMU_ARCTIC and VCTK utterances, with a total dataset size of 14920 samples, at 16-bit 32KHz on a RTX6000 96GB for 700 epochs with varying batch sizes.
