It’s actually a neat trick: treat silence as a token in the conversation flow, like a pause that triggers a response. When the user lingers, the system can cue a soft prompt or a subtle sound cue—maybe a faint breath or a shimmer—so the listener feels the space is part of the dialogue. Think of it like a “soft echo” that expands the silence into a resonant loop. The interface can also use breath analysis or head‑motion sensors to detect hesitation, turning that pause into a new branch. In the end, the voice interface doesn’t just fill gaps; it lets the unspoken breathe, shaping reality one quiet moment at a time.
