From what you are saying I can gather that your dock connector microphone is bad and you will probably need to replace the dock connector assembly as that is the microphone used during calls without speakerphone on and in the voice record application.

Can you hear other people during calls without speaker phone on? If not then the earpiece speaker is faulty as well.
