This version fixes the hidden mouth and makes the animation clearly
visible on mobile too.
Speaker Paragraphs
Welcome to Programmer's Picnic. This is the introduction paragraph.
In this demo, the avatar will start speaking, the mouth will
animate, and the active paragraph will be highlighted.
The main idea is simple. We use browser speech synthesis for
narration, and while the narration runs, the avatar enters speaking
mode. This gives a lively teaching experience.
Later, we will replace this demo face with our own photo based
avatar, or even build a more advanced version that looks like a real
speaking presenter.
