I’m so delighted that Pakistan won the ICC Champions Trophy but why are Indians making fun of the way the players speak English? English is not their national language, its Urdu. Do you also not see the effects of Colonialism still being prevalent today? You have internalized the prejudice, racism and the inferiority that you don’t notice that you’re actually embarrassed by your own language.
Although American English has [ɻ] it’s not uniform across all the US, it maybe a rhotic vowel or an alveolar approximant. I only included [ɻ] where it aligns with other retroflex consonants in the phonetic system.
Retroflexes are common and characteristic of India, Tibet, Java, Australia, Scandinavia, and Khoesan languages.
