 > Excel 格式生成 `.xlsx` 文件；聊天记录、朋友圈和收藏会将对应格式文件与必要资源一起打包为 ZIP。
 
+### 本地语音转文字（Whisper）
+
+聊天页可以在保留原语音播放的同时，按需将语音识别为中文；HTML、JSON、TXT 和 Excel 导出也可以选择把转写文字与原语音一起写入归档。转写结果按账号、消息 ID、音频内容和模型缓存在账号目录的 `_cache/voice_transcripts.sqlite3`，重复查看或导出不会再次识别。
+
+该能力是可选依赖，从源码运行时安装：
+
+```powershell
+uv sync --no-editable --extra voice-transcription
+```
+
+默认配置使用 CPU、`medium` 模型和中文识别，并且不会自动联网下载模型。推荐提前下载模型并指定本地目录：
+
+```powershell
+$env:WECHAT_TOOL_WHISPER_MODEL = 'D:\models\faster-whisper-medium'
+$env:WECHAT_TOOL_WHISPER_DEVICE = 'cpu'
+$env:WECHAT_TOOL_WHISPER_COMPUTE_TYPE = 'int8'
+```
+
+也可以明确允许首次识别时下载模型，此操作会访问 Hugging Face，模型文件较大：
+
+```powershell
+$env:WECHAT_TOOL_WHISPER_MODEL = 'medium'
+$env:WECHAT_TOOL_WHISPER_ALLOW_DOWNLOAD = '1'
+```
+
+使用 NVIDIA GPU 时可改为 `WECHAT_TOOL_WHISPER_DEVICE=cuda` 和 `WECHAT_TOOL_WHISPER_COMPUTE_TYPE=float16`。设置 `WECHAT_TOOL_WHISPER_ENABLED=0` 可以完全关闭该能力。隐私模式导出始终禁用语音转写，不会把语音内容写入归档。
+
+应用设置页也可以选择 CPU 或 NVIDIA GPU。GPU 探测、CUDA 初始化失败自动回退 CPU，以及 RTX 5060 验收步骤见 [RTX 5060 faster-whisper CUDA 验收说明](docs/rtx5060-faster-whisper-gpu.md)。

+
+| 功能 | Windows | macOS |
+| --- | --- | --- |
+| 数据库密钥自动获取 | 支持 | 不提供；请用支持 Mac 的同类本地工具获取后手动填写 64 位密钥 |
+| 数据库解密与离线分析 | 支持 | 支持 |
+| 图片密钥内存扫描 | 支持 | 支持；首次使用可能需要授予辅助功能或管理员权限 |
+| WCDB 实时消息、联系人和朋友圈 | 支持 | Apple Silicon 支持；Intel Mac 暂不支持实时 WCDB |
+| 聊天、朋友圈、联系人、收藏等导出 | 支持 | 支持 |
+| 账号全量归档 ZIP 导入与导出 | 支持 | 支持，并可与 Windows 双向迁移 |
+| 微信进程大图 Hook | 支持 | 不提供，这是 Windows 专属能力 |
+
+macOS 版本不会从微信进程提取数据库密钥。应用检测到 Mac 后只会显示获取方式提示；取得您本人账号的密钥并手动填写后，Apple Silicon Mac 上的数据库解密、实时消息、联系人、朋友圈、媒体、导出和迁移流程与 Windows 保持一致。
+
+### 从 Windows 迁移到 Mac
+
+1. 在 Windows 端打开全局导出，选择“账号数据归档”，同时包含数据库和资源文件。
+2. 将生成的 `wechat_archive_*.zip` 传到 Mac，不要手动解压或修改归档内容。
+3. 在 Mac 端进入“导入数据”，选择“账号归档 ZIP”，预览账号后确认导入。
+4. 导入器会校验每个文件的 SHA-256；若本地已有同名账号，会在完整导入成功后保留旧目录备份。
+
+已经由本项目解密并归档的数据，迁移后可直接离线查看；只有连接 Mac 上微信原始 WCDB 做实时读取时才需要手动填写数据库密钥。

+# RTX 5060 faster-whisper CUDA 验收说明
+
+状态：实现完成，待 RTX 5060 实机验收。更新：2026-07-29。
+
+## 适用范围
+
+本项目的语音转文字使用 `faster-whisper` 和 CTranslate2，不使用 PyTorch。因此，同类 PyTorch 音色克隆项目采用的 `cu128` wheel 安装路线不能直接复制到这里；本说明只复用其 RTX 50 系显卡驱动、磁盘、模型缓存与验收原则。
+
+默认设备是 CPU `int8`。在有 NVIDIA GPU 的机器上，设置页可选择 NVIDIA GPU；首次识别会使用 CUDA `float16` 加载模型。CUDA 探测或模型初始化失败时，会自动改用 CPU `int8`，不影响语音播放、聊天查看或导出任务。
+
+## 服务器前置检查
+
+先在目标机上执行只读检查：
+
+```bash
+nvidia-smi
+python3 --version
+ffmpeg -version
+df -h
+```
+
+`nvidia-smi` 必须能列出 RTX 5060。若它不可用，先由服务器管理员修复 NVIDIA driver；不要通过反复重装 Python 包排查驱动问题。
+
+本项目不需要安装 `torch`、`torchaudio` 或复用音色克隆项目的 wheelhouse。安装当前项目的语音依赖：
+
+```bash
+uv sync --no-editable --extra voice-transcription
+```
+
+当前锁定的 `CTranslate2 4.8.1` 在 Linux GPU 环境需要 NVIDIA driver、CUDA 12.x 和 cuDNN 9 运行库；PyTorch 的 `cu128` wheel 不会为 CTranslate2 提供这些库。先完成只读探测，再由服务器管理员或已获授权的维护人员按 CTranslate2 对应版本的官方安装说明补齐运行库。若采用 PyPI 的用户级 CUDA/cuDNN 包，也应只安装到本项目虚拟环境，并在启动后端的同一用户进程中设置其库路径；不要修改系统 `/usr`、全局 `LD_LIBRARY_PATH` 或共享 CUDA 安装。
+
+## 模型准备
+
+当前默认模型是 `Systran/faster-whisper-medium`，磁盘约 1.43 GiB。生产验收前应将模型放进目标机 Hugging Face 缓存，或将 `WECHAT_TOOL_WHISPER_MODEL` 指向完整的本地模型目录；默认禁止首次识别联网下载。
+
+建议把缓存放在数据盘，例如：
+
+```bash
+export HF_HOME=/mnt/sdb/wechat-data-analysis/hf-cache
+export WECHAT_TOOL_WHISPER_MODEL=medium
+export WECHAT_TOOL_WHISPER_ALLOW_DOWNLOAD=0
+```
+
+如果缓存尚未准备好，可在已获联网许可的维护窗口临时把 `WECHAT_TOOL_WHISPER_ALLOW_DOWNLOAD=1`，完成下载后恢复为 `0`。模型与缓存目录包含本地运行资产，不要提交到 Git。
+
+## CUDA 验收
+
+启动后端后，先检查 CTranslate2 是否能识别 CUDA：
+
+```bash
+python - <<'PY'
+import ctranslate2
+print("cuda device count:", ctranslate2.get_cuda_device_count())
+PY
+```
+
+期望设备数量大于零。然后打开应用的“设置 -> 语音转文字”：
+
+1. 页面应显示检测到的 NVIDIA GPU；RTX 5060 名称会由 `nvidia-smi` 提供。
+2. 选择“NVIDIA GPU”。该偏好会保存到应用 `output/runtime_settings.json`。
+3. 对一条清晰中文微信语音点击“转文字”，或用同一会话开启“语音转文字”导出。
+4. 重新打开设置页，确认“实际”显示为“NVIDIA GPU”。
+5. 导出结果仍需包含可播放的 `media/voices/*.mp3` 与中文转写文本。
+
+若 CUDA 探测通过但模型初始化失败，设置页会保留“NVIDIA GPU”为已选设备，并显示自动回退原因；“实际”应显示为 CPU。此时语音转写仍应成功，随后应记录 CTranslate2、NVIDIA driver 和 CUDA 运行库版本再排查。
+
+## 配置优先级
+
+推理设备优先级如下：
+
+```text
+WECHAT_TOOL_WHISPER_DEVICE 环境变量
+> 设置页保存的设备偏好
+> 默认 CPU
+```
+
+部署脚本若设置了 `WECHAT_TOOL_WHISPER_DEVICE`，界面会标记为“由启动环境变量固定”，避免用户误以为修改已生效。未设置该环境变量时，使用设置页选择 CPU 或 NVIDIA GPU。
+
+## 验收记录
+
+在 RTX 5060 服务器完成实测后，记录以下信息：
+
+```text
+nvidia-smi 的 GPU 名称、Driver Version、CUDA Version
+Python / faster-whisper / CTranslate2 版本
+CTranslate2 CUDA device count
+设置页检测结果、已选设备、实际设备、是否发生回退
+单条语音首次识别耗时与缓存后二次识别耗时
+导出中的语音数量、成功/失败/缓存统计
+```
+
+不要为了制造回退场景而在共享服务器上卸载驱动、修改系统 CUDA、重启机器或停止他人进程。自动回退路径由本地单元测试覆盖；服务器只验证真实 NVIDIA GPU 成功路径。
