Overall picture

Scalability is an issue when we have to use the cloud, but for u this is not an issue. KWS serves as a system level optimization before invoking cloud.

Datasets

1. Users? Few participants
2. Need? and keyword - To be aware of hunger through a physical embodiment.
3. Task - detect rumbling and actuate something
4. Interaction - Constant monitoring of the stomach for rumbling and nothing more
5. Real world background noises - yea only 2 classes, rumbling and no rumbling.

Audio data collection

Some data picked up at a certain sampling frequency and representation of voltage fluctuation. Which aspect of the signal do we actually have to pick up? Figure out what we have to pick up.

Raw waveforms are not good enough. Amplitude of the signal is very annoying to handle.

‘Align’ the signal to extract the initial part of the signal
