When the user taps the speed badge in the player, a bottom sheet slides up to reveal speed controls. The interface features a prominent vertical slider on the right, which the user can drag to adjust playback speed from slow to extremely fast. As the slider is scrubbed, the fill level animates smoothly, and the textual speed multiplier, words-per-minute count, and productivity boost percentage update in real-time. Crucially, the app provides instant audio feedback, playing a looped speech preview at the selected speed to help the user gauge their preference before committing.
