1. A method of evaluating perceptual delay impact on a teleconferencing conversation, comprising:

  • detecting a conversational event between a first participant and a second participant, the conversational event including a plurality of speech segments;

    in response to the conversational event being detected, obtaining at least one conversational parameter for the first and second participants, the at least one conversational parameter indicating a relationship between the plurality of speech segments in the conversational event; and

    determining a quality of the conversation according to a model based on the at least one conversational parameter, the model characterizing the quality with the at least one conversational parameter, wherein the obtaining the at least one conversational parameter comprises;

    determining a type of the conversational event, the type being selected from a group consisting of;

    a collision type where a first speech segment from the first participant is at least partially overlapped with a second speech segment from the second participant, anda non-collision type where adjacent speech segments of the plurality of speech segments are separated from one another; and

    obtaining the at least one conversational parameter based on the determined type of the conversational event, comprising, in response to determining that the conversational event is of the non-collision type, obtaining a first conversational parameter related to a waiting interval between a third speech segment initiated from the first participant and a next fourth speech segment received by the first participant from the second participant.
