Don’t see the problem with different pronunciations… I have a first name like Jules, I like it… indeed depending on whether people are French or English speaking they pronounce it differently—but that doesn’t bother me at all! It still feels very much like they are referring to me, and it feels like two versions of the same name, not two names.
This is actually a pretty interesting problem and the website doesn't do it full justice.
Do you want the same spelling? That's easy, but the pronunciation is quite often completely different. A good example is Jules in French vs English. In this scenario, you're effectively going by two differently-pronounced names in all face-to-face interactions, not that different from the folks from China or India who are adopting "Westernized" names abroad. The only perk is that you might not have to spell it out over the phone.
Do you want the same pronunciation? This is also fairly easy in many languages, but the spelling is likely to differ. An example of this might be Hannah versus Hana (English / Czech). This option makes verbal communications easy, but may confuse people who are trying to read your name out loud or to write it down - so any interactions with customer service are going to be mildly annoying.
Do you want both? For most languages, the list will beextremelyshort, perhaps half a dozen names such as "Anna". If you don't fall in love in one of these options, tough luck.
There is also a softer version of this goal: have a name that isn't native in the second language, but that is easy to spell and pronounce. For most people, this is probably the best compromise. It lets you keep your national identity, doesn't limit your choices too much, and minimizes friction.
