The Purpose
The current Alexa voice chrome on existing devices doesn't meet the needs of our future project. The challenges are, how to leverage the current visual style and make the Alexa chrome more stunning and obvious on visual, with better readability (10-foot experience); Also use Alexa chrome to differentiate more and more on-going functionalities and states.
Version 1 - Motion Enhanced
I try to keep it simple and stay within the same design (just increasing width for readability). Using motion to differentiate multiple on-going functionalities and states. 
Version 2 - Wave
Inspired by the traditional voice curve, this voice chrome is developed based off the current Alexa chrome, that has very similar ways reacting to people’s voice commands. The same visual/ motion is also brought into a circular container for other usages.
Version 3 - Particle
To embrace our new particle design language, I developed this particle based voice chrome with the same behaviors. The benefit of it is that we can easily morph (fly) particles into other elements. Because particles are dynamic and don’t have a solid shape.
