UX âm thanh đàm thoại

Make the interaction state understandable. Users need to know when the system is listening, processing, speaking, or waiting for clarification. Silence without explanation can be mistaken for a failure, while unnecessary spoken status messages can become distracting. Support natural turn-taking and interruption. A user may pause mid-sentence, correct a detail, or start speaking while the system responds. Test whether the application stops playback, preserves the correction, and avoids executing an outdated interpretation. Keep spoken responses concise enough to follow. Put the key information early and offer detail on request. For complex numbers, lists, or comparisons, provide a visual or text companion when possible. Do not require people to remember a long spoken menu. Design recovery and alternatives. Let users repeat, edit, cancel, or switch input modes. Evaluate the complete task with realistic noise, accents, accessibility needs, and network conditions. A pleasant voice should not hide unclear authority or an unverified action.
