Yes, it's an acronym, a mnemonic (Professional hazard as I am an engineer by trade and mien.)
I use this when creating and delivering a presentation - it's an easy way to remember the following keys for a successful speech.
- Colorful - Use words and phrases that create pictures and carry emotion.
- Articulate - Keep in mind your goal for the presentation, be organized and precise in your presentation. Try to make the complex simple and not the other way around.
- Lively - Use your body to communicate, your face to show emotion, your location in the room to make sure you are seen and heard, your hands to emphasize and demonstrate.
- Modulated - Use your voice fully, vary your volume, pitch, tempo and speed. Speak softly to draw the audience in, loudly to excite them.
