How do pronouce the name João, as in João Gilberto (the famous singer).?

Answer 1

In Portuguese, "J" is pronounced like the "G" in mirage,
the "J" in Taj Mahal and the "J" Rio de Janeiro.
The Portuguese "J" is equivalent to the "zh" symbol in the English
dictionary.

Pronounce The "O" as in go.

Pronounce The "Ao" as the "ou" in ouch, ounce and out.
