hailin a568558585 feat: replace speech_to_text with GTCRN ML noise reduction + backend STT ... Replace traditional on-device speech_to_text with a modern pipeline: - Record audio via `record` package with hardware noise suppression - Apply GTCRN neural denoising (sherpa-onnx, ICASSP 2024, 48K params) - Trim silence, POST to backend /voice/transcribe (faster-whisper) Changes: - Add /transcribe endpoint to voice-service for audio file upload - Add SpeechEnhancer wrapper for sherpa-onnx GTCRN model (523KB) - Rewrite chat_page.dart voice input: record → denoise → transcribe - Keep NoiseReducer.trimSilence for silence removal only - Upgrade record to v6.2.0, add sherpa_onnx, path_provider Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>		2026-02-22 07:59:15 -08:00
