Abstract
With interactive voice response services, it can be frustrating for a user to become stuck in a dialogue where the same question is asked repetitively. Here the wording of questions used by the system are varied throughout the dialogue depending upon how many times a user has visited a particular dialogue state during the call history. Furthermore the wording of the question is also varied in dependence upon the way in which the question was asked the last time the user was in a particular dialogue state.
Claims17
A method of operating an interactive voice response system to engage in a current dialogue with a user, said system having a dialogue model comprising
- a plurality of states and a plurality of interconnecting edges;
- a current state;
- user dialogue data indicating for a user a total number of visits to a state;
- in which the wording of a message for sending to the user at a state repeated in said current dialogue, is selected in dependence upon
- a) the current state;
- and
- b) the number of times the current state has been repeated during the current dialogue;
- and
- c) the total number of times the current state has been repeated during one or more previous dialogues with said user;
- and
- repeating a) through c) for multiple ones of said plurality of states.
An interactive voice response system having a dialogue model comprising:
- a plurality of states and a plurality of interconnecting edges;
- a current state;
- user dialogue data indicating for a user a total number of visits to a state;
- the system further comprising message wording selection means, for selecting the wording of a message for sending to the user at a state repeated in said current dialogue, in dependence upon
- a) the current state;
- and
- b) the number of times the current state has been repeated during the current dialogue;
- and
- c) the total number of times the current state has been repeated during one or more previous dialogues;
- and
- repeating a) through c) for multiple ones of said plurality of states.
A method of operating an interactive voice response system to engage in a current dialogue with a user, said interactive voice response system storing a dialogue model comprising
- a plurality of states and a plurality of interconnecting edges,
- a current state,
- user dialogue data indicating for a user a total number of visits to a state in the current dialogue and a total number of visits in one or more previous dialogues;
- wherein each state represents a stage of the dialogue and each interconnecting edge represents a transition between one stage of the dialogue and a subsequent stage,
- said method comprising the steps of
- finding the number of times the current stage has been repeated in the current and previous dialogues from said user dialogue data;
- and
- selecting the wording to be output by said interactive voice response system at a repeated stage of the current dialogue in dependence upon
- a) the current stage in the dialogue;
- and
- b) the number of times the current stage has been repeated, and
- c) the total number of times the user has been at this stage during one or more previous and
- repeating a) through c) for multiple ones of said plurality of states.
An interactive voice response system having a dialogue model comprising:
- a plurality of states and a plurality of interconnecting edges;
- a current state;
- user dialogue data indicating for a user a total number of visits to a state,
- wherein each state represents a stage of the dialogue and each interconnecting edge represents a transition between one stage of the dialogue and a subsequent stage,
- the system further comprising:
- stage repetition monitoring means arranged in operation to find the number of times the current stage has been repeated in the current and previous dialogues from said user dialogue data,
- message wording selection means arranged in operation to select the wording of a message for sending to the user at said current repeated stage, said message wording being selected in dependence upon
- a) the current stage in the dialogue;
- and
- b) the number of times the current stage has been repeated;
- and
- c) the total number of times the user has been at his stage during one or more previously dialogues;
- and
- repeating a) through c) for multiple ones of said plurality of states.
