"I think you said..." (therefore I am)
Another not-quite-human phrase out of voicebot System.Vocabulary. This one's aggressively anthropomorphic (though I've never heard it in human-to-human communication).
Ithinkyousaid, cl.
Placed before a repetition of the caller's input. Signals a tentative (or medium-level confidence) understanding of the input, and is typically followed by a request for confirmation. If used more than once for the same request, the initial syllable may be lengthened to indicate greater uncertainty (note: this can be perceived as a disdainful hesitation at the caller's apparent inability to answer the question).
Examples:
System: Would you like account status, bill payments or credit line increases?
Caller: I'm not sure, I want to know your interest rates.
System: Ithinkyousaid "account status", correct?
Caller: So you think?
System: Therefore I am.
Caller: You win.
