Feishu Voice Sender | 飞书语音发送器

发送音频文件到飞书聊天中，以语音消息形式展示（可直接点击播放）。

Send audio files to Feishu chat as voice messages (click to play inline).

核心发现 | Key Discovery

飞书语音消息需要：

1. 上传时使用 file_type=opus
2. 发送时使用 msg_type=audio

其他文件类型（mp3/stream）会以文件形式发送，需要下载才能播放。

Feishu voice messages require:

1. Upload with file_type=opus
2. Send with msg_type=audio

Other file types (mp3/stream) are sent as files requiring download.

快速开始 | Quick Start

# 发送语音消息（自动识别 .mp3/.m4a/.wav 等格式）
python3 scripts/feishu_voice_sender.py --file /path/to/audio.mp3

# 指定接收者
python3 scripts/feishu_voice_sender.py --file /path/to/audio.mp3 --receive-id ou_xxx
