The intelligibility of sentences recorded from the uterus of a pregnant ewe and from the near-term fetal sheep inner ear was judged by 30 listeners. Sentences were presented to the ewe at 95 and 105 dB SPL while sequential recordings of sound with a hydrophone and a cochlear microphonic (CM) with electrodes were made. Recordings were randomized and presented to listeners to judge the intelligib...

It is indispensable to establish an objective test methodology for noise-reduced speech. This paper proposes a new methodology which estimates word intelligibility of the noise-reduced speech from PESQ MOS (subjective MOS estimated by the PESQ). To evaluate the effectiveness of the proposed methodology, a word intelligibility test of the noise-reduced speech was performed by using four noise re...

We investigated the speech intelligibility differences of normal and bone-conduction stereo headphones of target speech localized at 45◦ on the horizontal plane when competing noise is present. This was our effort to study the possible effect of crosstalk found in bone-conduction headphones on speech intelligibility. All sound sources were localized on the horizontal plane. Target speech was lo...

The purpose of this study was to improve the speech processing strategy for cochlear implants (CIs) A speech preprocessing algorithm is presented to improve the speech intelligibility in noise. The algorithm improves the intelligibility by optimally redistributing the speech energy over time and frequency for a perceptual distortion measure, the algorithm is more sensitive to transient regions....

Post-processing methods can be used in mobile communications to improve the intelligibility of speech in adverse near-end noise conditions. This study proposes a phase spectrum modification method for intelligibility enhancement in mobile devices. The method first modifies the phase spectrum of speech in order to reduce the amplitude range of the signal. The amplitude level is then equalized to...

Cross-lingual voice conversion (XVC) transforms the speaker identity of a source to that target who speaks different language. Due intrinsic differences between languages, converted speech may carry an unwanted foreign accent. In this paper, we first investigate intelligibility and confirm performance degradation caused by accent/intelligibility issue. With goal generating native-sounding speec...

Automatic prediction of speech intelligibility is highly desirable in the speech research community, since listening tests are timeconsuming and can not be used online. Most of the available objective speech intelligibility measures are intrusive methods, as they require a clean reference signal in addition to the corresponding noisy/processed signal at hand. In order to overcome the problem of...

he intelligibility of speech in communication systems is generally reduced by interfering noise. This interference, which can take the form of environmental noise, reverberation, competing speech, or electronic channel noise, reduces intelligibility by masking the signal of interest. The reduction in intelligibility is particularly troublesome for listeners with hearing impairments, who have gr...

BACKGROUND intelligibility measures are limited to providing information on the severity level of clinical cases. A key limitation is that such measures are sensitive to changes in performance only in subjects with a determined severity level of speech disturbance. AIM to investigate the influence of stimuli type and transcription analysis on intelligibility measures of speakers with no commu...

A number of techniques based on correlation measurements have recently been proposed to provide an objective measure of intelligibility. These techniques are able to detect nonlinear distortions and provide intelligibility scores highly correlated with those given by human listeners. However, the performance of these techniques has not been found satisfactory for measuring the speech intelligib...
