Implementation of a neural network architecture for solving speech recognition tasks with limited vocabulary out of the box. This architecture is based on the Xception architecture, presented by François Chollet in 2017.

• It achieved state-of-the-art results with the Google Tensorflow Speech Commands data set, surpassing human performance in the most complex tasks.
• It works always in temporal domain, without needing to perform tedious and computationally expensive Fourier transforms
• It can be easily adapted to variable size audio clips and to different tasks

We suggest this architecture as the de facto solution when a voice commands recognition with restricted vocabulary task arises; considering the computing power is not a limiting factor.

If you are interested in run the code, please, follow the next steps.

1. Clone the repository
2. Navigate with your terminal inside the folder of the project and install the required libraries using the following command: pip install -r requirements.txt
3. Use the settings_template.json file in the root of the project as a template for creating a settings.json file and fill it with your configuration.
4. The directory config contains the settings for reproducing the results submitted with the paper. Choose one, select a seed and run it using the following command: python main.py [config filepath] [seed]

The seeds that have been used for generating the current results are the following ones 655321, 655322, 655323, 655324, 655325. Feel free to create new settings and store them in the config file to try new parameters.
