Script compliance using speech recognition
View Patent ↗Apparatus and methods are provided for using automatic speech recognition to analyze a voice interaction and verify compliance of an agent reading a script to a client during the voice interaction. In one aspect of the invention, a communications system includes a user interface, a communications network, and a call center having an automatic speech recognition component. In a second aspect of the invention, a script compliance method includes the steps of conducting a voice interaction between an agent and a client and evaluating the voice interaction with an automatic speech recognition component adapted to analyze the voice interaction and determine whether the agent has adequately followed the script.
1. A script compliance method for evaluating compliance of a live agent with a script from which the live agent reads when conducting a voice interaction with a live customer, the method comprising at least the following:
conducting the voice interaction between the live agent and the live customer in accordance with the script,
dividing data representing a portion of the voice interaction into a plurality of panels after being spoken by the live agent, wherein the panels correspond to respective sections of the script, wherein the dividing is based upon timestamps of the panels, and wherein the panels correspond to a single offer of a good or service, and
evaluating data representing a portion of the voice interaction with an automatic speech recognition component adapted to analyze the portion of the voice interaction and to determine a score representing a degree with which the live agent complied with the script during the portion of the voice interaction.
2. The script compliance method of claim 1 wherein said live agent is a telemarketing agent.
3. The script compliance method of claim 2 wherein said script includes an offer of goods or services.
4. The script compliance method of claim 1 wherein said voice interaction is carried on a communications network.
5. The script compliance method of claim 4 wherein said communications network is a publicly switched telephone network (PSTN).
6. The script compliance method of claim 4 wherein said communications network is the internet.
7. The script compliance method of claim 4 wherein said communications network includes a wireless component.
8. The script compliance method of claim 4 , wherein said voice interaction is a telephone call.
9. The script compliance method of claim 8 , wherein said telephone call is initiated by said live customer client.
10. The script compliance method of claim 1 wherein evaluating includes:
converting data representing said voice interaction into a digital signal comprising a spectral representation of said voice interaction,
comparing said digital signal to a reference standard comprising a known vocabulary, and
matching said digital signal to words and phrases contained in said reference standard.
11. The script compliance method of claim 1 further comprising:
performing an action based upon a determination obtained from said evaluating.
12. The script compliance method of claim 11 , wherein performing an action comprises transmitting a signal to said live agent corresponding to said determination.
13. The script compliance method of claim 11 , wherein performing an action comprises transmitting a signal to a reviewing authority corresponding to said determination.
14. The script compliance method of claim 11 , wherein performing an action comprises causing an entry to be made in a script compliance incentive system.
15. The script compliance method of claim 1 , further comprising:
reviewing the determination of the score.
16. The script compliance method of claim 1 , wherein the score is assigned by the automatic speech recognition component.
17. The script compliance method of claim 1 , further comprising assigning a respective score to each panel.
18. A system for evaluating compliance of a live agent with a script from which the live agent reads when conducting a voice interaction with a live customer via a communication network adapted to support the voice interaction, the system comprising at least the following:
a script compliance module including at least an automatic speech recognition component adapted to analyze data representing a portion of the voice interaction spoken by the live agent, the data being divided into a plurality of panels after being spoken by the live agent, with the panels corresponding to respective sections of the script, wherein the data being divided is based upon timestamps of the panels, and wherein the panels correspond to a single offer of a good or service, and to determine a score representing a degree with which the live agent complied with the script during that portion of the voice interaction, and
means for causing one or more actions to be taken based upon the determination by the automatic speech recognition component.
19. The system of claim 18 further comprising a call center including a plurality of agent workstations.
20. The system of claim 19 wherein each said agent workstation includes a telephone and a computer terminal.
21. The system of claim 18 wherein said live agent is a telemarketing agent.
22. The system of claim 18 wherein said live agent is a customer service agent.
23. The system of claim 18 wherein said means for causing one or more actions comprises means for transmitting a signal to said live agent corresponding to said determination.
24. The system of claim 18 wherein said means for causing one or more actions comprises means for transmitting a signal to a reviewing authority corresponding to said determination.
25. The system of claim 18 wherein said means for causing one or more actions comprises means for causing an entry to be made in a script compliance incentive system.
