Also, change the feature_sets_path variable to point to the directory location of the all_targets_mfcc_sets.npz file. Next, open 02-speech-commands-mfcc-classifier in Jupyter Notebook and change the dataset_path variable to point to the location of the unzipped Google Speech Commands dataset directory. The script will convert all speech samples (excluding the background_noise set) to their Mel Frequency Cepstral Coefficients (MFCCs), divide them into training, validation, and test sets, and save them as tensors in a file named all_targets_mfcc_sets.npz. Change the dataset_path variable to point to the location of the unzipped Google Speech Commands dataset directory on your computer. Open 01-speech-commands-mfcc-extraction in Jupyter Notebook. To learn more about it (and even contribute samples of your own voice!), please see this page. Since this example uses the Google Speech Commands dataset, I am required (and gratefully so) to give them credit for collecting and releasing this data for everyone to use. Getting StartedДЇirst, download and unzip the Google Speech Commands dataset on your computer. If you'd like to see an LED flash whenever you say the word 'stop,' you can connect an LED to the Raspberry Pi as shown in this tutorial. Follow these instructions to make sure you can record audio on your Raspberry Pi. This USB microphone from Adafruit worked well for me. ДЇor hardware, you will need a microphone for your Raspberry Pi to capture audio. Instructions to do that can be found here.

This guide offers some tips on how to do that.ДЇinally, you will need the TensorFlow Lite inference engine installed on your Raspberry Pi (or target deployment device). training samples) will require you to upload them to Google Drive and write different code to import them into your program. (This guide) will walk you through that process.ДЄlternatively, you can use Google Colab to run a Jupyter Notebook instance in the cloud, however, loading files (e.g.

#Cnn lite install

You will need to install TensorFlow, Keras, and Jupyter Notebook on your desktop or laptop.

The full articles that explain how these programs work and how to use them can be found here: In addition, it contains another Python example that uses TensorFlow Lite to run inference on the trained model to recognize the spoken word 'stop' on a Raspberry Pi. This project is a demonstration on how to use TensorFlow and Keras to train a Convolutional Neural Network (CNN) to recognize the wake word 'stop' among other words.
