As discovered by 9to5Mac reader RY, Siri will ask for help pronouncing a name if it has trouble understanding you the first time you pronounce a name. In addition, we have found that you can simply say, “That’s not how you pronounce [any name]” and Siri will go through the learning process.
Siri will ask you to say the name and then present a few options for how it thinks you said it. Once you've selected a pronunciation it will save it as the correct way to say the name.
The feature isn't fully functional on beta 1 but apparently beta 2 is right around the corner!
Take a look at the screenshots below...
