Well, "I would like to hear what you have to say" is the same thing as:
I would like to know what is on your mind.
Tell me what you think.
I would like to know your opinion.
What do you have to say about it?
Give me your honest opinion.
Speak up.
What is your argument?
The appropriateness of each of these options depends on the context for which it will be applied.
