Hi,

Can anyone suggest some good English speaking classes for kids 5 years old?
Speaks and understands english well.But need some courses/classes to learn and converse in American accent.

Don't worry about English, kids will learn by default..
I suggest you teach him Hindi (or your mother tongue) as that's where grown up kids are lacking.
One suggestion which might help is watch American channels, so your 5yr old can listen & get used to the accent.
