 After the installation, 🐸TTS provides a CLI interface for synthesizing speech using pre-trained models. You can either use your own model or the release models under 🐸TTS.

+You can boot up a demo 🐸TTS server to run inference with your models. Note that the server is not optimized for performance
+but gives you an easy way to interact with the models.
+
+The demo server provides pretty much the same interface as the CLI command.
+
+```bash
+tts-server -h # see the help
+tts-server --list_models  # list the available models.

+
+Run a TTS model, from the release models list, with its default vocoder.
+If the model you choose is a multi-speaker TTS model, you can select different speakers on the Web interface and synthesize
+speech.

 Here you can find a [CoLab](https://gist.github.com/erogol/97516ad65b44dbddb8cd694953187c5b) notebook for a hands-on example, training LJSpeech. Or you can manually follow the guideline below.
