How do I make a voice-reply via Apple Watch send, and not delay by a variable amount of time?

When I send an iMessage on Apple Watch there is only a "don't send" button, but I have no confirmation if/when this message is actually sent.

Many times when I send a message, later to check the time (within 5 seconds or so), the message is still "pending"

How do I

Get a confirmation that a message was actually sent (as in UX, a whooshing sound, a tap... etc)
Get rid of the delay when sending an iMessage. Sometimes when the message is syntactically correct, I want to just go on doing something else, like checking the HopStop's ETA to my destination.

Solution 1:

After you've dictated your message, you can immediately send it by opening Siri and saying "send".

Sending Apple Watch message immediately with Siri

You can also say "don't send" to cancel your message.
