Obviously pronunciation problem occurs when your not singing in your mother toungue.Its not only for revanth but for others too.I can point out that even legendary singers like ashaji,lata mangeshkar,diler paaji(mikas bro) etc who are established singers do blunders while singing in other languages.But still we ignore all those mistakes and appreciate them for their voice and talent.I am huge fan of shreya goshal voice and love all her telugu songs.I dont know about others but i m am soo proud of revanth for coming out of his comfort zone and trying in hindi music industry inspite of communication problem.I m soo amazed at his focus on his career and passion for music.He is very cute,sweet,clean hearted and ambitious young man.Love you revanth ❤️ Keep making telugites proud with your talent 🤗
