Embodiment approach 1

[0108] Hereinafter, an embodiment of a speech sound intelligibility evaluation system using an expected drop signal will be described.

[0109] First, an overview of a speech intelligibility evaluation system that evaluates speech intelligibility by presenting speech and text sequentially, measuring event-related potentials starting from the time the text is presented, detecting expected miss signals and P300 components, and evaluating speech intelligibility will be described. Next, the configuration and operation of the speech intelligibility evaluation system including the speech intelligibility evaluation device will be described.

[0110] 3.1. Structure of speech intelligibility evaluation system

[0111] Figure 5 The structure and usage environment of the speech sound intelligibility evaluation system 100 of this embodiment are shown. This speech sound intelligibility evaluation system 100 is described as an example corresponding to the system configuration of Embodi...

Embodiment approach 2

[0162] In the speech intelligibility evaluation system 100 of Embodiment 1, speech intelligibility of speech stored in the speech DB 71 is evaluated by sequentially presenting speech and characters and examining the presence or absence of an expected drop signal for the presentation of the text. However, since speech intelligibility was evaluated by ○ / × only by judging whether or not expectations were missed, there may be no resolution to the extent that slight differences in adjustment parameters appear in the intelligibility evaluation results. As mentioned above, the adjustment method of hearing aids has not been established, and several methods are mixed, and it is necessary to search for the most suitable adjustment method for each user. Therefore, in this embodiment, a speech intelligibility evaluation system for evaluating which tuning parameter is more appropriate among a plurality of tuning parameters will be described.

[0163] Tuning is realized by adjusting the gai...

Abstract

The speech articulation evaluation for evaluating the fitting status of a hearing aid requires the user to input replies and hence is burdensome to the user. A speech articulation evaluating system comprises: a biometric signal measuring unit that measures brain-wave signals of the user; a voice output unit that presents voices; a text output unit that presents texts; a speech-to-be-presented control unit that refers to a speech database, which holds a plurality of monosyllabic speeches, to decide a speech to be presented and that controls the voice and text output units to present the decided speech in such a manner that the voice and text are presented in the named order; a disappointment detecting unit that determines, from the user brain-wave signals measured by the biometric signal measuring unit, whether any positive components occur within a range of 600 ms plus or minus 100 ms starting from a time at which the text is presented; and a speech articulation evaluating unit that determines a speech articulation based on a result of the determination of the disappointment detecting unit.

Description

technical field [0001] The present invention relates to techniques for evaluating whether speech is actually heard clearly. More specifically, the present invention relates to what is required for evaluating the degree of "fitting" for obtaining a sound of an appropriate level for each user by adjusting the amount of amplification of the sound in hearing aids and the like. Speech intelligibility evaluation Speech intelligibility evaluation system. Background technique [0002] In recent years, due to the aging of society or the increase in opportunities to listen to loud music for a long time, elderly or acoustically hard of hearing people have increased, and hearing aids are used in daily life for the purpose of hearing conversations more clearly. users are increasing. [0003] The basic function of a hearing aid is sound amplification, but the amount of sound amplification needs to be adjusted for each user. For example, when the amount of amplification is insufficient,...
