Open source voice audio database for keyword spotting dataset


Is there an open source database for basic keyword audio to train our model from ?
I have seen the one published on Edge Impulse (yes/no/noise/unkown) but I wan wondering if an already database exist for easy keyword detection like “start” “stop” “on” “off” “up” “down” … ?

@thleroy I just saw this tutorial Training Models with Synthetic Data: End-to-End Keyword Spotting Walkthrough with Edge Impulse and this dataset Keyword Spotting.
