Is 说 in 听说 a resultative compliment?
'到' is the correct resultative complement for indicating the verb '听' is successfully carried out (听 = to hear; 听到 = have heard/ successfully hear)
听 and 说 in  &quot;听说&quot; are both verbs.
[听说] = [听 (indefinite object. e.g. 別人; 有人; 某人) 说] with the indefinite object omitted
You can use 听到 for any sound, but you can only use 听说 for human speech
