Something I found annoying of the assist pipeline is that it’s overly verbose. I don’t need to hear a message telling me that some light has been turn on every time.
Alexa does have a brief mode, that replaces unimportant responses by a simple “success” sound. Only responses that are worth listening to are spoken (errors, or those that it’s valuable to repeat back to the user to make sure the message was understood correctly, like those for setting a timer or adding something to the shopping list)
Such setting would be nice.
