Abstract: A speech of a conference participant is efficiently facilitated. A conference assist system indicates a score to recommend a speech to participants in a conference based on information inputted from an interface.

Abstract: In information conversion, a subjective similarity with target information is increased. A method for learning a conversion model is disclosed and includes performing a conversion process of converting conversion source information to post conversion information using the conversion model; performing a first comparison process of comparing the post conversion information with target information to calculate a first distance; performing a similarity score estimation process of using an evaluation model to calculate a similarity score with the target information from the post conversion information; performing a second comparison process of calculating a second distance from the similarity score; and performing a conversion model learning process of learning the conversion model using the first distance and the second distance as evaluation indices.

Abstract: In a speech signal processing device including a plurality of devices and a speech signal processing device, a first device of the devices is connected to a microphone to output a microphone input signal to the speech signal processing device. A second device of the devices is connected to a speaker to output a speaker output signal, which is the same as the signal output to the speaker, to the speech signal processing device. The speech signal processing device synchronizes a waveform included in the microphone input signal with a waveform included in the speaker output signal, and removes the waveform included in the speaker output signal from the waveform included in the microphone input signal.
