From 2facd355ab89a479c122fb9aa5c2b744be8cd664 Mon Sep 17 00:00:00 2001 From: msh-agent Date: Tue, 31 Mar 2026 07:07:21 +0800 Subject: [PATCH] feat(ai-nutritionist): Coze TTS and streaming robustness - Add Coze TTS endpoint and service; expose binary MP3 from controller. - Bypass ResponseFilter for /audio/speech so MP3 bodies are not UTF-8 wrapped. - UniApp: cozeTextToSpeech, TTS UI and play flow; SSE HTTP errors and diagnostics. - Document TTS in docs/features.md; extend test-0325-1 with curl verification.
