 # Text-to-Speech (TTS) with FastSpeech2 trained on LJSpeech
 
 This repository provides all the necessary tools for Text-to-Speech (TTS)  with SpeechBrain using a [FastSpeech2](https://arxiv.org/abs/2006.04558) 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.
+The pre-trained model takes texts or phonemes as input 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. It should be noted that if the input is text, we use a state-of-the-art grapheme-to-phoneme module to convert it to phonemes and then pass the phonemes to fastspeech2 model.
