A number of years ago, I was working with some friends on conlanging for a fictional society. At the time, we didn’t know about IPA or formalized sound descriptions like “voiceless bilabial plosive”, so we just described our sounds in terms of sounds that we were familiar with.
One such sound was written ‘R’, and described as “the sound of ‘r’ in certain British dialects, where very sounds like veddy”.
How does one describe that sound formally, and what is the IPA symbol for it?
