Just before I left the UK in 2018 there was starting to become this trend for voice verification on some services, in one particular one I had to go through the setup of (perhaps it was Virgin Media? I forget), they had me say "My voice is my passport" to train it on how I sound. I smiled to myself.
I had to do it on either Atom Bank or Starling (signed up for both at a similar time).
Monzo also have you recite something but it's something far less exciting like "My name is X and I bank with Monzo".
Charles Schwab does this, but tweaked it to, “my voice is my password.”
