🚀 Massively Multilingual Speech (MMS): Romani, Carpathian Text-to-Speech
This repository stores the text-to-speech (TTS) model checkpoint for the Romani, Carpathian (rmc-script_latin) language. It's part of Facebook's Massively Multilingual Speech project, aiming to offer speech technology across a wide range of languages. You can find more details about supported languages and their ISO 639-3 codes in the MMS Language Coverage Overview, and view all MMS-TTS checkpoints on the Hugging Face Hub: facebook/mms-tts.
MMS-TTS has been available in the 🤗 Transformers library since version 4.33.
✨ Features
Model Details
VITS (Variational Inference with adversarial learning for end-to-end Text-to-Speech) is an end-to-end speech synthesis model. It predicts a speech waveform based on an input text sequence. It's a conditional variational autoencoder (VAE) composed of a posterior encoder, decoder, and conditional prior.
A flow-based module, which consists of a Transformer-based text encoder and multiple coupling layers, predicts a set of spectrogram-based acoustic features. The spectrogram is decoded using a stack of transposed convolutional layers, similar to the HiFi-GAN vocoder. Given the one-to-many nature of the TTS problem (the same text input can be spoken in multiple ways), the model also has a stochastic duration predictor, enabling it to synthesize speech with different rhythms from the same input text.
The model is trained end-to-end with a combination of losses from variational lower bound and adversarial training. To enhance the model's expressiveness, normalizing flows are applied to the conditional prior distribution. During inference, the text encodings are up-sampled according to the duration prediction module and then mapped to the waveform using a cascade of the flow module and HiFi-GAN decoder. Due to the stochastic nature of the duration predictor, the model is non-deterministic, so a fixed seed is needed to generate the same speech waveform.
For the MMS project, a separate VITS checkpoint is trained for each language.
📦 Installation
MMS-TTS is available in the 🤗 Transformers library from version 4.33 onwards. To use this checkpoint, first install the latest version of the library:
pip install --upgrade transformers accelerate
💻 Usage Examples
Basic Usage
from transformers import VitsModel, AutoTokenizer
import torch
model = VitsModel.from_pretrained("facebook/mms-tts-rmc-script_latin")
tokenizer = AutoTokenizer.from_pretrained("facebook/mms-tts-rmc-script_latin")
text = "some example text in the Romani, Carpathian language"
inputs = tokenizer(text, return_tensors="pt")
with torch.no_grad():
output = model(**inputs).waveform
Advanced Usage
The resulting waveform can be saved as a .wav
file:
import scipy
scipy.io.wavfile.write("techno.wav", rate=model.config.sampling_rate, data=output)
Or displayed in a Jupyter Notebook / Google Colab:
from IPython.display import Audio
Audio(output, rate=model.config.sampling_rate)
