EMOTION TYPE CLASSIFICATION FOR INTERACTIVE DIALOG SYSTEM

摘要

Techniques for selecting an emotion type code associated with semantic content in an interactive dialog system. In an aspect, fact or profile inputs are provided to an emotion classification algorithm, which selects an emotion type based on the specific combination of fact or profile inputs. The emotion classification algorithm may be rules-based or derived from machine learning. A previous user input may be further specified as input to the emotion classification algorithm. The techniques are especially applicable in mobile communications devices such as smartphones, wherein the fact or profile inputs may be derived from usage of the diverse function set of the device, including online access, text or voice communications, scheduling functions, etc.

1. An apparatus for an interactive dialog system, the apparatus comprising:
a classification block configured to select, based on at least one fact or profile input, an emotion type code associated with an output statement, the emotion type code specifying one of a plurality of predetermined emotion types; and a text-to-speech block configured to generate speech corresponding to the output statement, the speech generated to have the predetermined emotion type specified by the emotion type code; wherein the at least one fact or profile input is derived from usage of a mobile communications device implementing the interactive dialog system.
