# Text-to-Speech (TTS) with Transformer trained on LJSpeech
This repository provides all the necessary tools for Text-to-Speech (TTS) with SpeechBrain using a [Transformer](https://arxiv.org/pdf/1809.08895.pdf) pretrained on [LJSpeech](https://keithito.com/LJ-Speech-Dataset/).
The pre-trained model takes in input a short text and produces a spectrogram in output. One can get the final waveform by applying a vocoder (e.g., HiFIGAN) on top of the generated spectrogram.
### Perform Text-to-Speech (TTS) - Running Inference
To run model inference pull the interface directory as shown in the cell below
Note: Run on T4-GPU for faster inference
```
!pip install --upgrade --no-cache-dir gdown
!gdown 1oy8Y5zwkLel7diA63GNCD-6cfoBV4tq7
!unzip inference.zip
```
```python
%%capture
!pip install speechbrain
%cd inference
```
```python
import torchaudio
from TTSModel import TTSModel
from IPython.display import Audio
from speechbrain.inference.vocoders import HIFIGAN
texts = ["This is a sample text for synthesis."]
model_source_path = "/content/inference"
# Intialize TTS (Transformer) and Vocoder (HiFIGAN)
my_tts_model = TTSModel.from_hparams(source=model_source_path)
hifi_gan = HIFIGAN.from_hparams(source="speechbrain/tts-hifigan-ljspeech", savedir="tmpdir_vocoder")
# Running the TTS
mel_output = my_tts_model.encode_text(texts)
# Running Vocoder (spectrogram-to-waveform)
waveforms = hifi_gan.decode_batch(mel_output)
# Save the waverform
torchaudio.save('example_TTS.wav',waveforms.squeeze(1), 22050)
print("Saved the audio file!")
```
If you want to generate multiple sentences in one-shot, pass the sentences as items in a list.
### Inference on GPU
To perform inference on the GPU, add `run_opts={"device":"cuda"}` when calling the `from_hparams` method.
Note: For Training the model please visit this [TTS_Training_Inference](https://colab.research.google.com/drive/1VYu4kXdgpv7f742QGquA1G4ipD2Kg0kT?usp=sharing) notebook
### Limitations
The SpeechBrain team does not provide any warranty on the performance achieved by this model when used on other datasets.
