Speaker definition with examples. Speaker is the voice that speaks behind the scene, expressing a writer's feelings or a situation.
For me personally, a fluent speaker/writer is someone who is thinking in the very language he is speaking/writing. He might have a thick accent, and his grammar might be off, but as long as he's not pausing even for a split second to translate words from his mother tongue, that's fluency.
