第一次

现在，用自己的话讲一遍。

不需要复述原句。像讲给一位没看过文章的同事听。

今天的重点：先说结论

00:00/ 03:00

轻触麦克风开始，录音只在你点击后进行

至少 20 秒 · 最长 03:00

Retell · round 1 · idle

record--idle

Mic button ink, CTA disabled. Recording never starts without a tap (D6).

GET /v1/sessions/{id} (stage = round1, max_round1_ms, min_valid_ms, previous_focus, language)
POST /v1/sessions/{id}/attempts {round, duration_ms, size_bytes, sha256, pause_count} → presigned PUT
PUT upload.url
POST /v1/attempts/{id}/submit

Haptics: start = impact(.medium); pause = impact(.light); auto-stop = notification(.warning).
Record button 96pt; VoiceOver label changes with state.
