A Quiet Tool That Knows What It's Doing

Hume's Voice Conversion Playground is clean to the point of feeling empty, and that's the whole point. The massive upload zone dominates the center with a soft dashed border and a simple "Click to add an audio file" prompt. It breathes. No clutter, no confusion about what to do first.

Smart Split Between Action and Settings

The left sidebar handles navigation with a well-organized hierarchy under Text to Speech, Speech to Speech, and platform tools like API keys and Billing. On the right, the voice selector sits in its own quiet panel showing "Male English Actor" with a play button and a Change option. That two-panel framing around the central workspace keeps everything reachable without competing for attention.

What Makes It Feel Different

The typography is restrained. Small, mostly monospaced labels on the Record Audio button give it a developer-tool texture. The grayscale GENERATE button at the bottom right feels intentionally muted until you're ready. Everything says "tool first, brand second." The little colored dots next to nav items are a subtle touch marking new features without being loud about it.
