Your video doesn’t show you changing the Siri voice though, you’re telling it your accent. There’s “Language”, which is your accent (“English (Australia)” in your case), and then “Siri Voice”, which is set to “Australian (Female)”. So of course if you tell it you have an Australian accent, but then speak with an American accent, words like “Light” will get confused, because the en_US “Light” sounds like the en_AU “Late”. If you have an American accent but want Siri to speak with an Australian one, set “Language” to “English - USA”, but then set “Siri Voice” to Australian. Don’t set Language to something that isn’t your accent!
