Content delivery system with barge-in mechanism and method of operation thereof
A method of operation of a content delivery system includes: receiving a command phrase based on determining an utterance type according to a travel context; determining a trigger match with a control unit based on the command phrase matching a trigger phrase; and stopping a prompt according to a prompt type based on the trigger match for controlling the prompt presented by a device.
1. A method of operation of a content delivery system comprising:
determining an utterance type of either receiving a command phrase or setting up a trigger phrase based on a travel context;
receiving the command phrase based on the utterance type according to the travel context;
determining a trigger match with a control unit based on the command phrase matching the trigger phrase representing a phrase for stopping a prompt;
stopping the prompt according to a prompt type representing an interruptible prompt based on the trigger match; and
continue playing the prompt representing the prompt type of an uninterruptible prompt even if the trigger phase is detected for controlling the prompt presented by a device.
2. The method as claimed in claim 1 wherein stopping the prompt includes stopping the interruptible prompt based on the command phrase matching the trigger phrase.
3. The method as claimed in claim 1 wherein stopping the prompt includes stopping the prompt with a prompt pattern having a plurality of a prompt type.
4. The method as claimed in claim 1 wherein stopping the prompt includes stopping the prompt based on a barge-in level for controlling the prompt being stopped.
5. The method as claimed in claim 1 further comprising validating a candidate phrase based on a confidence value meeting or exceeding a false alarm threshold.
6. A method of operation of a content delivery system comprising:
determining an utterance type of either receiving a command phase or setting up a trigger phase based on a travel context;
receiving the command phrase based on the utterance type;
determining a trigger match with a control unit based on the command phrase matching a trigger phrase representing a phrase for stopping a prompt;
stopping the prompt according to a prompt type representing an interruptible prompt based on the trigger match; and
continue playing the prompt representing the prompt type of an uninterruptible prompt even if the trigger phrase is detected for controlling the prompt presented by a device.
7. The method as claimed in claim 6 wherein determining the trigger match includes determining the trigger match based on the prompt type of the prompt.
8. The method as claimed in claim 6 wherein stopping the prompt includes stopping the prompt includes stopping a plurality of the interruptible prompt based on a propagation switch for controlling an extent of stopping the interruptible prompt.
9. The method as claimed in claim 6 further comprising generating a barge-in level based on the travel context for adjusting an extent of stopping the prompt.
10. The method as claimed in claim 6 further comprising overriding the uninterruptible prompt based on the travel context for stopping the uninterruptible prompt.
11. A content delivery system comprising:
a control unit for determining an utterance type of either receiving a command phrase or setting up a trigger phrase based on a travel context;
a communication interface, coupled to the control unit, for receiving the command phrase based on the utterance type according to the travel context;
wherein the control unit is for:
determining a trigger match based on the command phrase matching the trigger phrase representing a phrase for stopping a prompt,
stopping the prompt according to a prompt type representing an interruptible prompt based on the trigger match, and
continue playing the prompt representing the prompt type of an uninterruptible prompt even if the trigger phrase is detected for controlling the prompt presented by the device.
12. The system as claimed in claim 11 wherein the control unit is for stopping the interruptible prompt based on the command phrase matching the trigger phrase.
13. The system as claimed in claim 11 wherein the control unit is for stopping the prompt with a prompt pattern having a plurality of a prompt type.
14. The system as claimed in claim 11 wherein the control unit is for stopping the prompt based on a barge-in level for controlling the prompt being stopped.
15. The system as claimed in claim 11 wherein the control unit if for validating a candidate phrase based on a confidence value meeting or exceeding a false alarm threshold.
16. The system as claimed in claim 11 wherein the control unit is for:
determining the utterance type based on the travel context; and
wherein the communication interface is for receiving the command phrase based on the utterance type.
17. The system as claimed in claim 16 wherein the control unit is for determining the trigger match based on the prompt type of the prompt.
18. The system as claimed in claim 16 wherein the control unit is for stopping a plurality of an interruptible prompt based on a propagation switch for controlling an extent of stopping the interruptible prompt.
19. The system as claimed in claim 16 wherein the control unit is for generating a barge-in level based on the travel context for adjusting an extent of stopping the prompt.
20. The system as claimed in claim 16 wherein the control unit is for overriding the uninterruptible prompt based on the travel context for stopping the uninterruptible prompt.
