It's also interesting to see which words Google determines is bad, and which they mysteriously don't. The API does real time processing of sentence structure and will return "<three asterisks> on me" and "cum to the park" correctly, based on intent. (Sorry for the offensive speech!)
For a side project I needed to find every single English word/phrase the API would filter. Stumbled upon that in amazement.
(Side note: speaking a long list of bad words into a microphone very slowly was the most fun QA I've done)
