The extensions to the International Phonetic Alphabet, also extIPA symbols for disordered speech or simply the extIPA (Ext-IPA), are a set of letters and diacritics designed to augment the International Phonetic Alphabet for the phonetic transcription of disordered speech. Some of the symbols are occasionally used for transcribing features of normal speech. Many sounds found only in disordered speech are indicated with diacritics, though an increasing number of dedicated letters are used as well. Special letters are included to transcribe the speech of people with lisps and cleft palates. The extIPA repeats several standard-IPA diacritics that are unfamiliar to most people but transcribe features that are common in disordered speech. These include preaspiration , linguolabial , laminal fricatives and for a sound (segment or feature) with no available symbol (letter or diacritic). The novel transcription is used for an English molar-r, as opposed to for an apical r; these articulations are indistinguishable in sound and so are rarely identified in non-disordered speech. Sounds not found in non-disordered speech include fricative nasals (a.k.a. nareal fricatives) and percussive consonants. Sounds sometimes found in the world's languages that do not have symbols in the IPA include denasals and fricatives that are simultaneously lateral and sibilant. ==Letters== The full letters added by the extIPA are the following: The symbol is used with the alveolar click for , an alveolar click with percussive release, a "cluck". 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Extensions to the International Phonetic Alphabet」の詳細全文を読む スポンサード リンク
