Im using English (Singapore) because I find it recognises my accent better. Hahaha
Actually apart from the call screening, I'm also still waiting for "Overview Selection" to be made available for English (Singapore) - see

I know Overview Selection is available for English (US) but I'm not willing to forego the more accurate voice recognition for this feature alone. And this feature has been rolled out for like what, 4 months already, and it's still only available to English (US)...
And if this (apparently) simpler feature hasnt even rolled out yet to all English users after so long, I think one can only wait till Pixel 5 before the (apparently) more complexed call screening comes to Singapore.
