useAiVoice Voice Interaction

Browser Compatibility

This feature uses the browser's native Web Speech API for speech-to-text. In Google Chrome, it requires running in a 🪄 secure context (HTTPS or localhost) to work properly.

useAiVoice is a highly integrated voice processing hook. It not only encapsulates the browser's native speech-to-text (STT) capabilities but also features a built-in Web Audio analysis engine that outputs real-time high-fidelity waveform data, perfectly matching the AiVoiceTrigger component for dynamic visual feedback.

Key Features

• Visual Sync: Built-in frequency analyzer returns real-time amplitudes array to drive waveform animations directly.
• Physical Recording: Built-in MediaRecorder generates a .webm audio blob after recording.
• Smart VAD: Supports Voice Activity Detection to automatically stop recording when the user finishes speaking.
• Real-time STT: Supports interimResults to provide partial transcripts while the user is still speaking.
• Plug-and-Play: Automatically manages microphone permissions, AudioContext lifecycle, and proper cleanup.

Basic Usage

⚠️ Current environment doesn't support Web Speech API (Chrome recommended).
