+# 🐸💬 TTS Training Recipes
+
+TTS recipes intended to host bash scripts running all the necessary steps to train a TTS model with a particular dataset.
+
+Run each script from the root TTS folder as follows
+
+```console
+$ bash ./recipes/<dataset>/<model>/run.sh
+```
+
+All the outputs are held under the recipe directory unless you change the paths in the bash script.
+
+If you train a new model using TTS, feel free to share your training to expand the list of recipes.
