Call progress analyzing method for phone dialing system and device

Abstract

The invention provides a call progress analyzing method for a phone dialing system, which includes the following procedures: A dialing a called party number with known state through the phone dialing system, picking up the voice of the called party from a call wire as a source voice sample and selecting the source voice sample including keywords to perform feature extraction and form a keyword voice frame feature sequence template; B dialing the called party number through the phone dialing system, picking up the voice of the called party from the call wire as a target voice sample and performing the feature extraction to the target voice sample so as to form a target voice frame feature sequence; and C recognizing the target voice frame feature sequence by utilizing the keyword voice frame feature sequence template. The invention further provides a call progress analyzing device for the phone dialing system. The scheme of the call progress analyzing method and the call progress analyzing device can improve the detection accuracy rate of the state of the called part, acquire the accurate state of the calling and shorten detection delay.

Description

technical field [0001] The invention relates to the technical field of telephone outgoing dialing and the field of speech recognition, in particular to a method and device for analyzing call progress in a telephone outgoing dialing system. Background technique [0002] Outbound call refers to the operation of making a call, identifying the call status of the called party, and performing follow-up processing according to the call status. The call status includes but not limited to the other party connected, empty number, the called user is turned off, the called is not in the service area, the called is off, the called is busy with the call waiting function, the called is busy without the call waiting function, and the trunk is busy / The network is busy, the called user has set up call restrictions, the line failure of other operators, the called party should not answer for a long time, etc. The outbound telephone system refers to a system in which the computer automaticall...

Problems solved by technology

Through the signaling detection method, it can be detected that there is no connection, but there is a relatively large delay of nearly 30 seconds (recording notification 10 seconds, busy tone 20 seconds), and it is impossible to obtain whether the other party has been calling for a long time; through the standard information tone detection method, you can The detection is not connected, but there is a large delay of nearly 10 seconds, and it is impossible to obtain the long-term response of the other party; through the real voice detection method, the recording notification will be misjudged as a real-person connection, and it is impossible to obtain the long-term response of the other party should not

[0010] From the above analysis, it can be seen that even if the above three methods are used in combination, there will still be problems such as detection errors, too much detection delay, and the inability to know the exact status of the called party.
