The Extensions to the International Phonetic Alphabet for Disordered Speech, commonly abbreviated extIPA , are a set of letters and diacritics devised by the International Clinical Phonetics and Linguistics Association to augment the International Phonetic Alphabet for the phonetic transcription of disordered speech. Some of the symbols are used for transcribing features of normal speech in IPA transcription, and are accepted as such by the International Phonetic Association. 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 symbo ...

Lateral Fricative
A lateral is a consonant in which the airstream proceeds along one or both of the sides of the tongue, but it is blocked by the tongue from going through the middle of the mouth. An example of a lateral consonant is the English ''L'', as in ''Larry''. Lateral consonants contrast with central consonants, in which the airstream flows through the center of the mouth. For the most common laterals, the tip of the tongue makes contact with the upper teeth (see dental consonant) or the upper gum (see alveolar consonant), but there are many other possible places for laterals to be made. The most common laterals are approximants and belong to the class of liquids, but lateral fricatives and affricates are also common in some parts of the world. Some languages, such as the Iwaidja and Ilgar languages of Australia, have lateral flaps, and others, such as the Xhosa and Zulu languages of Africa, have lateral clicks. When pronouncing the labiodental fricatives , the lip blocks the ai ...

Voiceless Velar Lateral Fricative
The voiceless velar lateral fricative is a rare speech sound. As one element of an affricate, it is found for example in Zulu and Xhosa (see velar lateral ejective affricate). However, a simple fricative has only been reported from a few languages in the Caucasus and New Guinea. Archi, a Northeast Caucasian language of Dagestan, has four voiceless velar lateral fricatives: plain , labialized , fortis , and labialized fortis . Although clearly fricatives, these are further forward than velars in most languages, and might better be called ''prevelar''. Archi also has a voiced fricative, as well as a voiceless In linguistics, voicelessness is the property of sounds being pronounced without the larynx vibrating. Phonologically, it is a type of phonation, which contrasts with other states of the larynx, but some object that the word phonation implies v ... and several ejective lateral velar affricates, but no alveolar consonant, alveolar lateral fricatives or affricates ...

Voiceless Palatal Lateral Fricative
The voiceless palatal lateral fricative is a type of consonantal sound, used in a few spoken languages. This sound is somewhat rare; Dahalo has both a palatal lateral fricative and an affricate An affricate is a consonant that begins as a stop and releases as a fricative, generally with the same place of articulation (most often coronal). It is often difficult to decide if a stop and fricative form a single phoneme or a consonant pai ...; Hadza has a series of palatal lateral affricates. In Bura, it is the realization of palatalized and contrasts with . The extensions to the IPA transcribes this sound with the letter ( with a belt, analogous to for the voiceless alveolar lateral fricative), which was added to Unicode in 2021. If distinction is necessary, the voiceless alveolo-palatal lateral fricative may be transcribed as ( retracted and palatalized ) or as advanced ; these are essentially equivalent, since the contact includes both the blade and body (but no ...

Lateral Lisp
Lisp (historically LISP, an abbreviation of "list processing") is a family of programming languages with a long history and a distinctive, fully parenthesized prefix notation. Originally specified in the late 1950s, it is the second-oldest high-level programming language still in common use, after Fortran. Lisp has changed since its early days, and many dialects have existed over its history. Today, the best-known general-purpose Lisp dialects are Common Lisp, Scheme, Racket, and Clojure. Lisp was originally created as a practical mathematical notation for computer programs, influenced by (though not originally derived from) the notation of Alonzo Church's lambda calculus. It quickly became a favored programming language for artificial intelligence (AI) research. As one of the earliest programming languages, Lisp pioneered many ideas in computer science, including tree data structures, automatic storage management, dynamic typing, conditionals, higher-order functions, recur ...

Gentium
Gentium (, from the Latin for "of the nations") is a Unicode serif typeface family designed by Victor Gaultney. Gentium fonts are free and open source software, and are released under the SIL Open Font License (OFL), which permits modification and redistribution. Gentium has wide support for languages using the Latin, Greek, and Cyrillic scripts, as well as the International Phonetic Alphabet (IPA) and other phonetic notation, excluding mostly paleographic and medievalist characters. Gentium includes over 4,500 glyphs and advanced typographic features through OpenType and formerly Graphite. Gentium was designed for use at 10-11 points. Wide counters and low stroke contrast improve readability at small point sizes. Long ascenders allow diacritics stacking. In 2003, the Gentium font was awarded a Certificate of Excellence in Type Design from the Association Typographique Internationale (ATypI) as one of the best designs of the previous five years.
