对话式交互规范：对话中不存在“错误”-设计处理错误的策略思维导图

“What was that?” “Say that again?”

“Sorry, what time?” “I missed that number.”

“First, what’s your favorite color?”——”What’s your favorite color?” “Sure, what movie would you like to see?”——”To get started, what movie do you want to see?”

“What time is this for?”——”Sorry，what time?” “For when?”—— “What time would you like to book this for?”

“I have your name and email from your account, so now all I need is your phone number.” “You can give me the day, the time, or both.”

“I could put you down for 6 p.m. for now, does that work? “Do you want to  finish this later?”

有用的策略

有时候用户可能会只是随意尝试下，看系统会如何回应，所以也需要为这部分做好准备

可以提醒用户任务完成进度，处于何处，以及回到主路径的方式

可能也需要主动的把控局面，根据你程序的角色画像以及自信的程度，去推动对话继续进行
