SpeechT5 for Arabic (TTS task)

Here we use the pretained weights from ArTST and fine-tuned using huggingface implementation of SpeechT5 on Classical Arabic ClArTTS for speech synthesis (text-to-speech).

ArTST was first released in this repository, pretrained weights.

Uses

🤗 Transformers Usage

You can run ArTST TTS locally with the 🤗 Transformers library.

  1. First install the 🤗 Transformers library, sentencepiece, soundfile and datasets(optional):
pip install --upgrade pip
pip install --upgrade transformers sentencepiece datasets[audio]
  1. Run inference via the Text-to-Speech (TTS) pipeline. You can access the Arabic SPeechT5 model via the TTS pipeline in just a few lines of code!
from transformers import pipeline
from datasets import load_dataset
import soundfile as sf

synthesiser = pipeline("text-to-speech", "MBZUAI/speecht5_tts_clartts_ar")

embeddings_dataset = load_dataset("herwoww/arabic_xvector_embeddings", split="validation")
speaker_embedding = torch.tensor(embeddings_dataset[105]["speaker_embeddings"]).unsqueeze(0)
# You can replace this embedding with your own as well.

speech = synthesiser("لأنه لا يرى أنه على السفه ثم من بعد ذلك حديث منتشر", forward_params={"speaker_embeddings": speaker_embedding})
# ArTST is trained without diacritics.

sf.write("speech.wav", speech["audio"], samplerate=speech["sampling_rate"])
  1. Run inference via the Transformers modelling code - You can use the processor + generate code to convert text into a mono 16 kHz speech waveform for more fine-grained control.
from transformers import SpeechT5Processor, SpeechT5ForTextToSpeech, SpeechT5HifiGan
from datasets import load_dataset
import torch
import soundfile as sf
from datasets import load_dataset

processor = SpeechT5Processor.from_pretrained("MBZUAI/speecht5_tts_clartts_ar")
model = SpeechT5ForTextToSpeech.from_pretrained("MBZUAI/speecht5_tts_clartts_ar")
vocoder = SpeechT5HifiGan.from_pretrained("microsoft/speecht5_hifigan")

inputs = processor(text="لأنه لا يرى أنه على السفه ثم من بعد ذلك حديث منتشر", return_tensors="pt")

# load xvector containing speaker's voice characteristics from a dataset
embeddings_dataset = load_dataset("herwoww/arabic_xvector_embeddings", split="validation")
speaker_embedding = torch.tensor(embeddings_dataset[105]["speaker_embeddings"]).unsqueeze(0)

speech = model.generate_speech(inputs["input_ids"], speaker_embedding, vocoder=vocoder)

sf.write("speech.wav", speech.numpy(), samplerate=16000)
