Abstract

A programmed conversation recording system presents a caller with a sequence of messages and records caller responses to these messages during respective calling periods. According to this invention, pauses in the caller response are automatically detected and timed and a patience interval is provided which varies in real time during the recording period as a function of the duration of the caller response. The recording period is automatically terminated when the duration of a pause in the caller response exceeds the patience interval. By varying the patience interval in real time during the recording period, the recording system can be programmed to respond properly, even to responses to complex questions.

Claims

1. In a response recording system of the type comprising means for automatically presenting a caller with at least one message and means for automatically recording a caller response to said at least one message during a recording period, the improvement comprising:

means for automatically detecting a pause in the caller response;

means for providing a patience interval which varies during the recording period as a function of the duration of the caller response; and

means for automatically terminating the recording period when the duration of the pause exceeds the patience interval.

2. The invention of claim 1 wherein the pause detecting means comprises a syllabic detector.

3. The invention of claim 1 wherein the patience interval providing means comprises:

means for storing a list of patience intervals; and

means for selecting one of the stored list of patience intervals in accordance with the duration of the caller response.

4. The invention of claim 1 wherein the response recording system includes means for automatically presenting the caller with a second message after the recording period has been terminated by the terminating means;

and means for automatically recording a caller response to the second message.

5. The invention of claim 1 wherein the response recording system is adapted for connection to a telephone line to receive the caller response via the telephone line.

6. The invention of claim 1 wherein the patience interval increases in magnitude with increasing response duration in a selected range of response duration.

7. The invention of claim 1 wherein the patience interval decreases in magnitude with increasing response duration in a selected range of response duration.

8. The invention of claim 1 wherein the patience interval increases and then decreases in magnitude with increasing response duration in a selected range of response duration.

9. In a response recording system of the type comprising first means for automatically presenting a caller with a plurality of messages and second means for automatically recording caller responses to at least selected ones of the messages during respective recording periods, the improvement comprising:

means for automatically detecting a pause in one of the caller responses;

means, responsive to the detecting means, for generating a first signal indicative of the duration of the pause;

means for generating a second signal indicative of the duration of the caller response;

means for storing at least one sequence of patience intervals, each sequence corresponding to at least one of the messages, and each patience interval corresponding to a respective response duration;

means for using the second signal to select the corresponding patience interval such that the selected patience interval varies during the recording period; and

means for automatically causing the first means to present a next one of the messages to the caller when the first signal exceeds the selected patience interval.

10. The invention of claim 9 wherein the response recording system is adapted to receive caller responses via a telephone line.

11. The invention of claim 9 wherein the patience intervals in at least one sequence of the patience intervals increase in magnitude with increasing response duration.

12. The invention of claim 9 wherein the patience intervals in at least one sequence of the patience intervals decrease in magnitude with increasing response duration.

13. The invention of claim 9 wherein the patience intervals in at least one sequence of the patience intervals increase and then decrease in magnitude with increasing response duration.

14. The invention of claim 9 wherein the storing means stores a plurality of sequences of patience intervals, and wherein the invention further comprises means for designating a corresponding one of the sequences of patience intervals for each respective one of the caller responses.

15. In a response recording system of the type comprising first means for automatically presenting a caller with a plurality of messages and second means for automatically recording caller responses to at least selected ones of the messages during respective recording periods, the improvement comprising:

means for automatically detecting a pause in the caller responses;

means for providing a plurality of patience intervals, each varying during a called response as a separate respective function of the duration of the caller response, each patience interval associated with at least one of the caller responses;

means for designating the associated one of the patience intervals for each of the caller responses; and

means for automatically terminating the respective recording period when the duration of the pause exceeds the designated patience interval.

16. The invention of claim 15 wherein the pause detecting means comprises a syllabic detector.

17. The invention of claim 15 wherein the response recording system is adapted for connection to a telephone line to receive the caller response via the telephone line.
