Voice-to-text technology has been around for a while - but safe to say they haven't ironed out the kinks.
Siri, the disembodied female voice that lives in Apple products, is one of the most well-known of those bots - and even she needs to be spoken to a certain way before she'll do what you ask.
As the father of this Twitter user found out.
Kellie (@puskas) tweeted a screengrab showing her dad's first attempt using Siri to text her.
Siri wasn't cooperating.
You'll have to be a bit nicer to her than that!
