This is a series where I walk through the engineering steps and challenges on how to build an Artificial intelligence voice assistant, similar to google home or Amazon Alexa, with Python and PyTorch on a Raspberry Pi. I leverage the latest machine and deep learning techniques to achieve this.

In this video, I show how you can build a wake word detector (keyword spotting) using recurrent neural networks specifically LSTMs.
