Hello. Dear Ms.Sue, I would be very grateful for your help.

Question

Which do you think is correct:
1) he heard the sweet voice of his little daughter or
2) he heard a sweet voice of his daughter?
Maybe, both are OK? I feel that it is only "the" in the phrase "the voice of his little daughter", but maybe the adjective makes "a" also possible?
Thank you a lot.

Answer 1

1 is better. 2 needs "the" before "sweet."
