It never seems like Siri can understand what you're saying when you actually need her to work – whether it's asking for directions to a certain address or asking her to search for something on the internet only to be told: "Sorry, I didn't quite catch that".

Well, this guy figured out why: apparently you have to speak to her using a trombone.

YouTube musician Paul the Trombonist posted a screenshot of his wife's phone earlier this week depicting five very peculiar text messages.

Paul and his wife had been chatting about grocery shopping when he sent a large block of text that read something like: "Woo woo wooo hoo hoo wah wah hoo woo wah."

This is because Paul had accidentally activated Siri's voice recognition feature before playing his trombone.

The hilarious result? A five-text transcript of trombone sounds, courtesy of Siri.

If you don't believe that the amusing fluke is possible, Paul tested it out again later and posted footage of his experiment to YouTube.
