How to pronounce the ñ & rr sound well?

ñ is easy, it's like "nia"
rr i still can't..

rr   呢個音
如果係之前加 t音   會唔會似d呢?
當然要讀得超快
好似 radio  讀做  tradio

rr 同 tr, gr, dr, etc 中既r 係兩個唔同既音

tr, gr, dr, etc 中既r 同比兩個vowel 夾住既r, e.g. para, querer, vera, etc 既r 係同一個發音

除非有人特登將tr, gr, dr, etc 中既r 當rr咁讀. 呢個情況唱opera 同italian 會比較常見.

舉個例, 正常情況你講gracias 唔會講到grrrrrracias咁, 除非你有意將個r拖長佢黎讀
