    ABSTRACT: To collect the daily speech materials and to discuss the speech development of normal-hearing pre-school children. Based on the database of daily speech materials of children who are 3 to 5 years old, from separate monosyllabic word to syllable,analysis the frequency of words and compare them with adults. In the spoken words of children who are 3 to 5 years old, we can find all Mandarin phonemes. With independent sample t test, it was shown that there is no significant difference in the distributing of phonemes between children and adults. Children who are 3 years old have developed the phonetic system of the language basically.

    ABSTRACT: By means of investigating how the benefit and the influence factors are for the pre-lingual deaf adolescents who received cochlear implantation (CI) METHODS: A questionnaire survey was conducted among 30 prelingually deaf adolescents-cochlear implant recipients, aged 9 approximately 20, 15 of which began to use hearing aid before the age of 6, and 19 of which had received speech testing after the CI, and their families to understand the degree of satisfaction, anticipation of the outcome. Nine of the 15 patients who began to use hearing aid before the age of 6 communicated by the oral communication/labial reading model (oral group), and 10 of the other 15 patients who had not used hearing aid after the age of 6 mainly communicated by sign language (sign group). The satisfaction score of the group with a hearing aid fitting history was 3.93 +/- 0.88, significantly higher than that of the group without a hearing aid fitting history (3.00 +/- 1.13, P < 0.05). The scores of speech production ability in vowel, consonant, single syllable, disyllable, trisyllable, and short sentence in the groups with and without a hearing aid fitting history were 76%/52%, 64%/45%, 71%/26%, 82%/96%, 68%/12%, and 49%/13% respectively (all P < 0.05), and there was no significant difference in the speech production ability in tone (P > 0.05) between these 2 groups. There were no significant differences in the total satisfaction degree, satisfaction degree in speech sound, and satisfaction degree in environmental sound between the oral group and sign group (all P > 0.05). The scores in vowel, consonant, single syllable, disyllable, trisyllable, short sentence, and tone of the oral and sign group were 74%, 60%, 64%, 61%, 57%, 43%, 27% and 43%, 39%, 26%, 26%, 20%, 6%, 5% respectively (all P > 0.01). The anticipation of the patient and the parents about outcome before implantation was negatively correlated with the satisfaction degree after implantation, (gamma = -0.479, P < 0.05). Cochlear implantation benefits greatly the deaf adolescent; however, it is necessary to establish a specific evaluation system according to recipients' needs.

    ABSTRACT: We have developed a database application software using Delphi 6 to manage patients' data with a cochlear implant. The software contains multiple functional modules used to record patients' medical and audiological evaluation, evaluation of hearing abilities, evaluation of speech and language status, evaluation of psychological status, rehabilitation and specific training, processor programming, follow-up and support, etc.. It also can generate various reports, convert patient's data to SPSS format for statistics purpose. The aim of the software is to help the decision-making for a cochlear implant, to develop a better pre-operative procedures that can predict how well a patient will perform with a cochlear implant, and also to reach a level by future research that will enable all implant patients to be "better-performing" patients.
