What is the list of all existing voice commands which create an intent with vnd.google.fitness.VIEW
action and vnd.google.fitness.data_type/com.google.heart_rate.bpm
mime type?
The documentation shows only two of them:
but I've discovered more, for example:
the documentation also states those are "Example Phrases". The reason for that it's because such a list does not exist.
Voice commands on those type of platforms (Google Now, Siri) use quite more advanced algorithms to recognize what a person wants, and not just recognize the actual words. That is called "natural voice".
That all means, that a "List of voice commands" does not exist as the platform is capable of adapt and interpret variations.
