-Speech inference can be done with **Catalan Matcha-TTS** by loading the model remotely with the HF hub.  
+Speech end-to-end inference can be done together with **Catalan Matcha-TTS**. 
+Both models (Catalan Matcha-TTS and Vocos) are loaded remotely from the HF hub.  
 
+First, export the following environment variables to include the installed espeak-ng version:
+
+```bash
+export PYTHON=/path/to/your/venv/bin/python
+export ESPEAK_DATA_PATH=/path/to/espeak-ng/espeak-ng-data
+export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/espeak-ng/lib
+export PATH="/path/to/espeak-ng/bin:$PATH"
+
+```
+Then you can run the inference script:
+```bash
+cd Matcha-TTS
+python3 matcha_vocos_inference.py --output_path=/output/path --text_input="Bon dia Manel, avui anem a la muntanya."
+
+```
+You can also modify the length scale (speech rate) and the temperature of the generated sample:
 ```bash
-pip install git+https://github.com/langtech-bsc/Matcha-TTS.git@dev-cat
+python3 matcha_vocos_inference.py --output_path=/output/path --text_input="Bon dia Manel, avui anem a la muntanya." --length_scale=0.8 --temperature=0.7
 
 ```
