Expert Answer
When we talk, our vocal card generate sound. Sound is a form of energy.
Hence energy from our body is utilized for the vocal hard to do some work so that sound energy is generated.
I do not know, when we think, are we using energy?
May be brain needs some additional blood flow to thing, hence to get additional blood flow we need energy
