So you have to whisper?

  No, you have to think that you're saying it - using your inner voice, which when used still triggers minute signals to the muscles used for speech.

    I don't think your inner voice triggers anything, though. I find it more likely that you have to move your tongue as if you're speaking, but without opening your mouth.
