The Voiceless/Playing With

Basic Trope: A character who never speaks on screen, despite apparently being capable of it.
 * Straight: Alice only communicates with her friends with notes or expressive gestures.
 * Exaggerated: Alice never speaks. Not to her friends, to her family... Nobody.
 * Justified: Alice has laryngitis.
 * Alice is mute.
 * Alice has taken a vow of silence.
 * Inverted: Alice is a Motor Mouth.
 * Subverted: Alice seems to be voiceless, but starts speaking normally halfway through the show.
 * Double Subverted: ...but that was the local ventriloquist, Bailey, throwing her voice.
 * Parodied: Alice's vocal cords have cobwebbed over.
 * Alice's friend Charlie remarks on how eloquent and musical a speaker she is. We never hear this.
 * There is a body swap episode, and Alice stays silent despite her mind being that of Denise.
 * Deconstructed: Alice's speechlessness leads to a case of Poor Communication Kills.
 * Reconstructed: Alice stays silent most of the time, but speaks when it is really needed.
 * Zig Zagged: Alice mostly never speaks, then sometimes does.
 * Averted: Alice always communicates through talking.
 * Enforced: Alice's actor has laryngitis when they're about to shoot, so the scenes are rewritten so that an already dialogue-light part has no dialogue in it.
 * Lampshaded: "Alice really isn't talkative around us, is she?"
 * Invoked: Alice never speaks because if she spoke, her powers would kill everyone in a six mile radius.
 * Defied: "I'm going to talk, and everyone who might be watching is going to hear me!"
 * Discussed: "..." "Honestly Alice, that's your answer to everything."
 * Conversed: "Is Alice mute?" "I...honestly don't know."
