In order to study the development of speech in infants with cleft palate, we investigated the development of consonant articulation in two cases (A, B) with cleft soft palate and in two cases (C, D) with cleft lip and palate before and after palatoplasty. We taperecorded their consonants in meaningful speech sounds and transcribed them.We made the following observations: (1) The frequency of consonants in meaningful speech sounds did not vary with the type of cleft or the timing of palatoplasty, and increased radically in the latter half of the second year and the first half of the third year. (2) Glottal stops occurred in the pre-palatoplasty periods but had almost disappeared three to ten months after palatoplasty in cases A, B, and C, whose velopharyngeal function was competent. (3) The speech sounds of these three cases were judged to be intelligible when the numbers of glottal stops decreased, the numbers of voiceless stops accounted for over 50% of all stops, and bilabial voiceless stops [p] appeared.

就学前幼児6例の人工内耳装用経験に基づき, 初回マッピングとその後のマップの調整や装用状況について調べた。 初回マッピングでは, T/Cレベルを幼児の表情や行動の変化によって測定するが, 先天性難聴幼児5例中4例がCレベル測定時に目を覆ったり部屋の電気がピカピカしていると視覚刺激のように感じ, その後の2回目のT/Cレベル測定を嫌がり, 内2例はヘッドセットを装着することも嫌がって, 終日装用まで時間がかかった。 このことから幼児のT/Cレベル測定では, 目を覆う反応の前に見られる身体接触を求めるなどをCレベルとして次の電極の測定に移り, 測定刺激が不快レベルにならないよう慎重にする必要があると考えられた。 また, マップ作製後の装用では, 感度調節ツマミを最適感度レベルより低い値にして, 装用時の音への反応を観察しやすくすることが, マップの調整に有効であった。

In 289 patients with cleft lip and palate, cleft palate, submucous cleft palate and congenital velopharyngeal insufficiency, various aspects of pharyngeal stops were studied: incidence, place of articulation, factors which influence the occurrence, and elicited consonants (except/k/).Observing those videofluoroscopy of the patients, we selected ones whose back of the tongue (and epiglottis) touched the posterior pharyngeal wall while they pronounced [ka]. The incidence of pharyngeal stops for [ka] was approximately 9%.Pharyngeal stops were divided into three types according to the site of articulation: oropharynx, oro-and laryngopharynx and epiglottis. The oro-and laryngopharynx type, in which the epiglottis as well as the back of the tongue made contact with the posterior pharyngeal wall, was most common. Among the factors which influence the occurrence of pharyngeal stops were the following vowels. When low vowels followed/k/, such as [ka, ko], pharyngeal stops were most frequent. They were somewhat less frequent during the production of [ku], and rare during that of [ki, ke]. It was observed that the site of articulation of [ka, ku, ko] was different from that of [ki, ke] in a single patient. Moreover, the occurence of pharyngeal stops was influenced by the number of syllables: that is, they appeared less frequently in words or sentences than in single syllables. Pharyngeal stops were also observed during the production of/p/and/t/.Pharyngeal stops are considered to be variable abnormal articulations.
