Acquiring audio data with a smartphone

As with all ML problems, data acquisition is the first step to take, and Edge Impulse offers several ways to do this directly from the web browser.

In this first recipe, we will learn how to acquire audio samples using a mobile phone.

Getting ready

Edge Impulse offers a straightforward and efficient method for data acquisition using smartphones through internet connectivity. This approach is so simple and intuitive that even people with no technical background will find it easy to use.

The only factor to consider before preparing the dataset is related to the number of audio recordings to take for training the model, outlined in the upcoming subsection.

Collecting audio samples for KWS

The number of samples depends entirely on the nature of the problem—therefore, no one approach fits all. In our scenario, 25 recordings for each class, each corresponding to the utterance to recognize (redgreen...
