It will affect the sound, but not the same for every speaker. Since you
have a German mail address, consider how differently "Chemie" is
pronounced in German depending on which part of Germany you are from.
Now consider someone speaking with a French or Indian or Chinese
accent. Different languages have different phonemes, and humans
generally learn to distinguish between them (and to disregard variances)
in the first years.

The difficulty is to *recognise* it correctly. Was that tangle of sound
waves an "l" or an "r"? This not as unambiguous as you seem to think.
So a speech-to-text program may hear "right" when the speaker was really
saying "light". If you have only the output from that program you must
determine whether "right" is correct or must be corrected to "light".
