I was reading a book about accents at a local library and there was a chapter where the author says "some varieties of a language are more aesthetically pleasing than others". Some accents are considered “tops”, and these are the ones spoken by the Royals, the elite, intellectuals and distinguished academics, etc
Consequently, a person might regard their own accent with distaste and may try to imitate the accent of the elite where they live or the elite who live in great cultural centers; for example, a French-Canadian in Paris, a Brummie in London, or a Texan in Boston.
As for the answer to my question, there is one, I know. It's a phrase, with 3 or 4 words, and no foreign terms. It is mentioned in the book on sociolinguistics and accents I was reading. I simply can't remember it now. I'm looking for a phrase describing the person or the condition.
For Clarity: I'm not saying that all French-Canadians, Brummies or Texans are, or should ever be, ashamed/embarrassed/self-conscious of their accents, but it is possible.
Best Answer
He/she felt linguistically discriminated or to be precise accentually discriminated.
The condition is called accentism.
Update:
phonetic accommodation: Phonetic imitation is the unintentional, spontaneous acquisition of speech characteristics of the interlocutor.
