I also prefer the female British accents but that's exactly what excites me and is so awesome about this. These aren't just samples that are being stitched together anymore. This "learning" that is being done can be applied later to any of the voices in Apple's catalog. Once they get the data of the synthesis out there, they'll more than likely update all the languages and intonations to match. I would imagine that the biggest hurdle with this is that different languages and accents have different nuances. As with most things, they're just starting with English and then will move everything over to all the other options, including the British accents. I don't think we're too far off from a future where you'll be able to pick the age, gender, and voice of your assistant in the same way that characters selection is done in most modern video games.
