Text to speech pronunciation is different on emulator and device

Question

I am developing an app that read in US-EN, but notice that pronunciation is different on the emulator versus on a real device (Samsung tablet). For example, "reservoir" is pronounced something like "reserve wire" on the emulator, but correctly on the tablet. Can I rely on correct pronunciation on untested devices?

Thanks!

Answer 1

Define correctly. Is it aunt rhyming with "font" or aunt which sounds exactly like "ant"? In some areas of the world its pronounced one way, in some others. There is no such thing as globally "correct" english pronunciation (which is another word that differs- is the middle syllable "nun" or "noun")?

As for pronunciation in general- OEMs and users can install any text to speech they want. So no, you can't expect it to sound a certain way.
