Actually my windows phone 8 device (currently a circa 2013 820) isn't far off that already. Not joking. It goes:

1. Hold down start for 2-3 seconds

2. Say "Send text to Joe Bloggs"

3. Wait a couple of seconds for it to work it out.

4. Say your message. It gets this right nearly 100% of the time.

5. Asks you if that's ok or do you want to add some more

6. Say yes and it sends it.

It has an option to read and dictate texts to you as well but I've never used it as I think that would annoy me. Might go and play with it now.

You can do a fair bit with it. It can find a pizza place locally and call it without any trouble (my main use case :-)
