Well picked up. I think that is really a colloquial thing. My wife is Australian, and she does tend to switch between "aitch" and "haitch" for the pronunciation.

Good tip to remember in future to keep it consistent. I am thinking also that US viewers might be discomfited by her pronunciation of "data". Once again, the Aussie way is "darr-ta" rather than "day-ta".

gotcha! I'm not a native speaker, so I had to double-check how to pronounce the H :)

I can't decide on that. The voice is amazing, and in the US we see foreign accents as "trendy". However if the target market was US (which I have no idea if it is), I wouldn't be surprised if A/B testing would favor an American accent. Just because we hear it all day, so we are much more used to it.

People are going to need to take this more seriously. Bosses are cracking down on pronunciation - https://www.youtube.com/watch?v=c3y0CD2CoCs

I thought that video was hilarious!! Thank for posting! :D

This is how most Australians pronounce H (as 'haitch').
