Definition

Two-Way Voice Conversation 是一种实时双向语音交互模式——AI Agent 主动拨叫用户用户接听后可随时提问Agent 实时响应。与传统的单向播报TTS或录音通知不同真正的双向对话意味着用户可以打断、追问、澄清而不是被动接收广播式信息。

Why It Matters

传统通知推送、邮件、SMS的本质是单向广播——Agent 发送信息用户被动接收无法即时互动。Two-Way Voice Conversation 打破了这一限制:

  • 即时澄清:用户可以说"等等,哪封邮件?"或"现在价格多少?"Agent 立即查询并回答
  • 动态深度:用户可追问"为什么跌了?"引导 Agent 深入解释
  • 决策支持:电话中即可做出决策("帮我取消"、"确认出席"),无需挂断后额外操作

Contrast with One-Way Notification

Aspect One-Way Notification Two-Way Voice Conversation
Direction Agent → User Agent ↔ User
User Action Passive receive Active query
Depth Fixed message Dynamic based on questions
Decision Making Post-call action needed Can decide on-call
Latency Tolerance Low (pre-composed) Higher (live response)

Design Considerations

  • 模型速度通话场景需要低延迟响应建议使用快速模型Haiku 级别)减少等待
  • 上下文管理Agent 需要在通话中维护对话上下文,切换话题时自然流畅
  • 通话礼仪Agent 应简洁明了,不说废话,直接回答用户问题
