Patent Document ID: 9149214
Application ID: 13630113

Base Claim:
1. An annoyance judgment system comprising: one or more memories storing a speech sound database retaining a plurality of monosyllabic speech sounds such that, for each speech sound, the speech sound and a reference latency of an electroencephalogram negative component corresponding to the speech sound are retained in association; and circuitry which in operation is configured to: measure an electroencephalogram signal of a user; determine a monosyllabic speech sound to be presented by referring to the speech sound database; present the determined speech sound to the user; judge annoyance of the output speech sound by comparing a peak latency of a negative component of the measured electroencephalogram signal in a range from 50 ms to 350 ms from a starting point, the starting point being a point in time at which the speech sound is presented, against the reference latency corresponding to the determined speech sound that is retained in the speech sound database; and output gain settings for presenting speech sounds based on the annoyance judgment.

Claim 8:
8. The annoyance judgment system of claim 1 , wherein the circuitry further is configured to select a type of acoustic aiding process for the presented speech sound, and is configured to modify data of the speech sounds retained in the speech sound database based on the selected acoustic aiding process.
