SPEECH FILTERING DEVICE, INTERACTION SYSTEM, CONTEXT MODEL TRAINING DATA GENERATION DEVICE, AND COMPUTER PROGRAM

Document Type and Number:

WIPO Patent Application WO/2024/014230

Kind Code:

A1

Abstract:

This speech filtering device, which prevents an output of an expression that can be problematic in an interactive system that outputs speech in an interactive form, comprises: a context model which has been trained in advance to output a probability vector which has, as elements, probabilities in which each word included in a prescribed word group appears in the context in which the speech is placed when receiving an input of a word vector column that represents speech; and a determination unit 456 for inputting, to the context model, the word vector column that represents the speech and determining whether to nullify or approve the speech according to whether a value is equal to or greater than a threshold, the value being determined as a prescribed function of the probability vector output from the context model in response to the input.
