A method comprising: at a system comprising one or more processors and a memory storing one or more programs for execution by the one or more processors: receiving speech data from a first participant of a session; receiving speech data from a second participant of the session; and when the speech of the second participant temporally overlaps the speech of the first participant, determining an amount by which the speech of the second participant overlaps the speech of the first participant, wherein when the overlap is less than a first predetermined threshold amount of a terminal portion of the speech of first participant, the speech of the first participant is outputted and then the speech of the second participant is outputted in accordance with an adjustment of the speech of one or more participants of the session that includes delaying output of the speech of the second participant; and when the overlap is more than a first predetermined threshold amount of the terminal portion of the speech of the first participant, the speech of the first participant is outputted and at least a portion of the speech of the second participant is dropped by outputting the at least a portion of the speech of the second participant to some but not all participants of the session. at a system comprising one or more processors and a memory storing one or more programs for execution by the one or more processors: receiving speech data from a first participant of a session; receiving speech data from a second participant of the session; and when the speech of the second participant temporally overlaps the speech of the first participant, determining an amount by which the speech of the second participant overlaps the speech of the first participant, wherein when the overlap is less than a first predetermined threshold amount of a terminal portion of the speech of first participant, the speech of the first participant is outputted and then the speech of the second participant is outputted in accordance with an adjustment of the speech of one or more participants of the session that includes delaying output of the speech of the second participant; and when the overlap is more than a first predetermined threshold amount of the terminal portion of the speech of the first participant, the speech of the first participant is outputted and at least a portion of the speech of the second participant is dropped by outputting the at least a portion of the speech of the second participant to some but not all participants of the session. when the overlap is less than a first predetermined threshold amount of a terminal portion of the speech of first participant, the speech of the first participant is outputted and then the speech of the second participant is outputted in accordance with an adjustment of the speech of one or more participants of the session that includes delaying output of the speech of the second participant; and when the overlap is more than a first predetermined threshold amount of the terminal portion of the speech of the first participant, the speech of the first participant is outputted and at least a portion of the speech of the second participant is dropped by outputting the at least a portion of the speech of the second participant to some but not all participants of the session.
