A voice processing device includes: a processor; and a memory which stores a plurality of instructions, which when executed by the processor, cause the processor to execute: detecting a first utterance section included in a first voice and a second utterance section included in a second voice; specifying an overlapping section within which the first utterance section and the second utterance section overlap with each other; calculating a first utterance continuation section from a start point of the overlapping section to an end point of the first utterance section; and evaluating an impression regarding the first voice at least on the basis of information relating to a length of the first utterance continuation section.

Voice processing device and voice processing method for impression evaluation

An utterance condition determination device includes a memory configured to a voice signal of a first speaker and a voice signal of a second speaker, and a processor configured to estimate an average backchannel frequency that represents a backchannel frequency of the second speaker in a period of time from a voice start time of the voice signal of the second speaker to a predetermined time based on the voice signal of the first speaker and the voice signal of the second speaker, to calculate the backchannel frequency of the second speaker for each unit of time based on the voice signal of the first speaker and the voice signal of the second speaker, and to determine a satisfaction level of the second speaker based on the estimated average backchannel frequency and the calculated backchannel frequency.

Utterance condition determination apparatus and method

A voice processing apparatus including a memory, and a processor coupled to the memory and the processor configured to acquire a first input signal containing a first voice, and a second input signal containing a second voice, obtain a first signal intensity of the first input signal, and a second signal intensity of the second input signal, specify a correlation coefficient between a time sequence of the first signal intensity and a time sequence of the second signal intensity, determine whether the first voice and the second voice are in the conversation state or not based on the specified correlation coefficient, and output information indicating an association between the first voice and the second voice when it is determined that the first voice and the second voice are in the conversation state.
