Is it the same as "speaking on behalf of" ? Or does "speaking for someone else" mean trying to give an opinion about something that someone else is experiencing without you yourself going through that experience ? If so, what is a single word or a phrase that can be used to express that ?
EDIT
Let's say a bunch of friends including John and myself are discussing about going on a picnic. I know that John doesn't like picnicking. So I say, in the presence of John, "John doesn't like to go on picnics". And John says (annoyedly) "speak for yourself". In this context, which one is meaningful; "speaking for John" or "speaking on behalf of John" ?
Thank you.

"Speaking for" someone and "speaking on behalf of" someone mean essentially the same thing, with one fairly major difference. To really be "speaking on behalf" of someone, that someone needs to consent to you doing so. So if someone says they are "speaking on behalf of" John, they are implying that John knows what they are doing and approves of it. You can "speak for" someone without their consent, as in your example between you and John. So "speaking for" can have a negative connotation, but does not necessarily. "Speaking on behalf of" does not have a negative connotation, unless you have reason to believe that they are not telling the truth.
