What do we call, when a person pronounce a few words in some unique way of his own, i.e., a wrong pronunciation and this is not because of any speech disorder. It's just that for them such words are tongue-twister.
This usually happens in case of speaking a foreign language, and speaker cannot avoid mispronouncing some words.
I can use "dialect" or "speech style" to say a sentence like this:
this person has a speech style of his own.
I don't want to use words like: mispronounce/wrong/peculiar.
Do we have a name for this type of speaking manner, or any suitable phrase to describe this situation?
