ap-guangzhou - 方式:录音文件识别 CreateRecTask(SourceType=1 Base64)
- 限制:音频 < 5MB,超长视频自动分段
能力边界
本工具最佳适用场景:
- ✅ 教程/科普/口播类 — 单人讲述、普通话清晰、背景干净,识别准确率高
- ✅ 产品测评/新闻解说 — 结构清晰的内容
- ⚠️ 段子/搞笑短剧 — ASR 仅转录文字,丢失语气、节奏、反讽和画面信息,AI 分析可能偏离原意
- ❌ 多人对话/背景嘈杂 — 识别质量严重下降
- ❌ 纯画面/表情驱动的幽默 — 无文字可依,不适用
注意:AI 分析仅基于转录文字,不包含画面、表情、动作等视觉信息,也不具备人类生活经验和文化直觉,对搞笑视频的解读可能不准确。
