I don’t use Siri for much, and I certainly don’t have it always listening. But I did hack out a useful Shortcut to record my blood pressure and heart rate to Apple Health.

I say, “Add blood pressure <pause> 120 over 80 plus 60.” Then I use the shortcut to parse the string on the / and +, and record it to Health.

The hard part was finding delimiters that Siri would consistently record as a single character. That and realizing I needed a manual review step to make sure Siri didn’t happily pump garbage into my logs.
