This paper describes a logatome discrimination test for the assessment of speech perception in cochlear implant users (CI users), based on a multilingual speech database, the Oldenburg Logatome Corpus, which was originally recorded for the comparison of human and automated speech recognition. The logatome discrimination task is based on the presentation of 100 logatome pairs (i.e., nonsense syllables) with balanced representations of alternating “vowel-replacement” and “consonant-replacement” paradigms in order to assess phoneme confusions. Thirteen adult normal hearing listeners and eight adult CI users, including both good and poor performers, were included in the study and completed the test after their speech intelligibility abilities were evaluated with an established sentence test in noise. Furthermore, the discrimination abilities were measured electrophysiologically by recording the mismatch negativity (MMN) as a component of auditory event-related potentials. The results show a clear MMN response only for normal hearing listeners and CI users with good performance, correlating with their logatome discrimination abilities. Higher discrimination scores for vowel-replacement paradigms than for the consonant-replacement paradigms were found. We conclude that the logatome discrimination test is well suited to monitor the speech perception skills of CI users. Due to the large number of available spoken logatome items, the Oldenburg Logatome Corpus appears to provide a useful and powerful basis for further development of speech perception tests for CI users.

Although it is well known that the speech produced by the deaf is generally of low intelligibility, the sources of this low speech intelligibility have generally been ascribed either to aberrant articulation of phonemes or inappropriate prosody. This study was designed to determine to what extent a nonsegmental aspect of speech, formant transitions, may differ in the speech of the deaf and of the normal hearing. The initial second formant transitions of the vowels /i/ and /u/ after labial and alveolar consonants (/b, d, f/) were compared in the speech of six normal-hearing and six hearing-impaired adolescents. In the speech of the hearing-impaired subjects, the second formant transitions may be reduced both in time and in frequency. At its onset, the second formant may be nearer to its eventual target frequency than in the speech of the normal subjects. Since formant transitions are important acoustic cues for the adjacent consonants, reduced F 2 transitions may be an important factor in the low intelligibility of the speech of the deaf.

Quality Measurements

The purpose of the present research was to examine the relation between speech quality and speech intelligibility. Speech quality measurements were made using continuous discourse and a category rating procedure for the following dimensions: intelligibility, pleasantness, loudness, effort, and total impression. Measurements were made using a group of listeners with normal hearing for a set of stimulus conditions in which intelligibility varied, and for a set of stimulus conditions in which intelligibility was held constant near 100%. When ratings were made for a set of stimulus conditions in which intelligibility was allowed to vary (a) intersubject reliability was high (i.e., different listeners interpreted the dimensions in a similar manner); and (b) the speech quality dimensions of intelligibility, effort, and loudness were indistinguishable. When ratings were made for a set of stimulus conditions in which intelligibility was held constant (a) intersubject reliability was reduced, indicating that different listeners interpreted the dimensions in different ways; (b) most listeners rated each dimension differently, indicating that the dimensions were unique; and (c) across listeners, no single dimension was highly correlated with total impression. These results can be used in order to examine the relation between speech quality and speech intelligibility.

Objectives -to determine the normative data of sentence speech intelligibility in a free sound field and to estimate the applicability of the Russian Matrix Sentence test (RuMatrix) for assessment of the hearing aid fitting benefit. Material and methods. 10 people with normal hearing and 28 users of hearing aids with moderate to severe sensorineural hearing loss were involved in the study. RuMatrix test both in quiet and in noise was performed in a free sound field. All patients filled in the COSI questionnaire. Results. The hearing impaired patients were divided into two subgroups: the 1st with high and the 2nd with low hearing aid benefit, according to the COSI questionnaire. In the 1st subgroup, the threshold for the sentence intelligibility in quiet was 34.9 ± 6.4 dB SPL, and in noise -3.3 ± 1.4 dB SNR, in the 2nd subgroup 41.7 ± 11.5 dB SPL and 0.15 ± 3.45 dB SNR, respectively. The significant difference between the data of both subgroups and the norm was registered (p

Vocants are precursors to speech and are facially neutral. The presence of these speechlike vocalizations was evident during the precursors to mature phonology called “protophones”. The prosodic feature of duration of the nuclei plays a crucial role in the shift of prelexical to mature speech, since speech intelligibility is closely related to the control of duration. The aim of this work is to determine whether cochlear implants (CIs) positively trigger language acquisition and the development of verbal skills. Recent literature findings are compared and discussed with the performance of two Greek congenitally hearing-impaired infants who were matched with three normal-hearing (NH) infants. This work highlighted an important weakness of the prosodic abilities of young infants with CIs.

Цель исследования - оценка негативного влияния приобретенной односторонней глухоты на качество жизни пожилых пациентов. Выполнен проспективный анализ амбулаторных карт на предмет выявления пожилых пациентов с односторонней глухотой с последующим анкетированием при помощи опросников PSQ, HHIE, THI. Основными критериями включения являлись возраст старше 60 лет, одностороннее снижение слуха с порогами восприятия, соответствующими глухоте (>90 дБ), внезапное начало заболевания и продолжительность глухоты не более 5 лет. У пациентов с односторонней глухотой, которые составили основную группу исследования (n=25), по сравнению с пациентами контрольной группы (n=25) были выявлены повышенный уровень стресса и ухудшение качества жизни, о чем свидетельствуют данные опроса. Пациенты предъявляли жалобы на неудовлетворительную разборчивость речи, выраженный шум в пораженном ухе, невозможность определить источник звука и необходимость адаптироваться к определённым акустическим ситуациям, что требовало повышенной концентрации внимания, приводило к переутомлению, повышенной раздражительности, нервозности и когнитивным нарушениям. The study aimed to assess a negative impact of an acquired single-sided deafness on quality of life of the elderly. Prospective analysis of outpatient records was carried out to identify elderly patients with single-sided deafness using pure tone audiometry. The main inclusion criteria were age over 60, ≥90 dB threshold of an affected ear, ≤30 dB threshold of an intact ear, an acquired single-sided hearing loss with sudden onset and deafness duration less than 5 years. Taking inclusion criteria into account two groups were formed: the main group with single-sided deaf patients (n=25) and the control group of normal hearing patients (n=25). All participants were surveyed with PSQ, HHIE, THI questionnaires. There were revealed some changes in psychological status in the group of patients with single-sided deafness in comparison with the group of normal hearing participants. The scores of the questionnaires showed increased stress and anxiety levels and deterioration in quality of life. Patients with single-sided deafness complained about severe tinnitus in an affected ear, worse speech intelligibility in noisy environment and a constant need to adapt to the different acoustic situations that in turn badly affected psychoemotional homeostasis, intensifying stress severity, and quality of life.
