E2 TTS - Pytorch

Implementation of E2-TTS, Embarrassingly Easy Fully Non-Autoregressive Zero-Shot TTS, in Pytorch

Appreciation

• Manmay for contributing working end-to-end training code!

Install

$ pip install e2-tts-pytorch

Usage

import torch

from e2_tts_pytorch import (
    E2TTS,
    DurationPredictor
)

duration_predictor = DurationPredictor(
    transformer = dict(
        dim = 512,
        depth = 8,
    )
)

mel = torch.randn(2, 1024, 100)
text = ['Hello', 'Goodbye']

loss = duration_predictor(mel, text = text)
loss.backward()

e2tts = E2TTS(
    duration_predictor = duration_predictor,
    transformer = dict(
        dim = 512,
        depth = 8,
        skip_connect_type = 'concat'
    ),
)

loss = e2tts(mel, text = text)
loss.backward()

sampled = e2tts.sample(mel[:, :5], text = text)
