 # Vocoder with HiFIGAN trained on LibriTTS
 
-This repository provides all the necessary tools for using a [HiFIGAN](https://arxiv.org/abs/2010.05646) vocoder trained with [LibriTTS](https://www.openslr.org/60/). The sample rate used for the vocoder is 16000 kHz.
+This repository provides all the necessary tools for using a [HiFIGAN](https://arxiv.org/abs/2010.05646) vocoder trained with [LibriTTS](https://www.openslr.org/60/) (with multiple speakers). The sample rate used for the vocoder is 16000 kHz.
 
 The pre-trained model takes in input a spectrogram and produces a waveform in output. Typically, a vocoder is used after a TTS model that converts an input text into a spectrogram.
 
+Alternatives to this models are the following:
+- [tts-hifigan-libritts-22050Hz](https://huggingface.co/speechbrain/tts-hifigan-libritts-22050Hz) (same model trained on the same dataset, but for a sample rate of 22050 Hz)
+- [tts-hifigan-ljspeech](https://huggingface.co/speechbrain/tts-hifigan-ljspeech)  (same model trained on LJSpeech for a sample rate of 22050 Hz).
