In articulatory phonetics, the manner of articulation is the configuration and interaction of the articulators (speech organs such as the tongue, lips, and palate) when making a speech sound. One parameter of manner is stricture, that is, how closely the speech organs approach one another.
These sounds occur in English, where they are denoted with letter combinations such as sh, ch, g, j or si, as in shin, chin, gin and vision. Retroflex (e.g. [ʂ]): with a flat or concave tongue, and no palatalization. There is a variety of these sounds, some of which also go by other names (e.g. "flat postalveolar" or "apico-alveolar").
Rather, the same symbol is used for all coronal places of articulation that are not palatalized like English palato-alveolar sh, or retroflex. To disambiguate, the bridge ([s̪, t̪, n̪, l̪], etc.) may be used for a dental consonant, or the under-bar ([s̠, t̠, n̠, l̠], etc.) may be used for the postalveolars.
Typically the position of the sound within a word is considered and targeted. The sound appears in the beginning of the word, middle, or end of the word (initial, medial, or final). Take for example, correction of an "S" sound (lisp). Most likely, a speech language pathologist (SLP) would employ exercises to work on "Sssssss."
The Extensions to the International Phonetic Alphabet for Disordered Speech, commonly abbreviated extIPA / ɛ k ˈ s t aɪ p ə /, [1] 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.
It occurs in Icelandic as well as an intervocalic and word-final allophone of English /t/ in dialects such as Hiberno-English and Scouse. The voiceless alveolar lateral fricative [ɬ] sounds like a voiceless, strongly articulated version of English l (somewhat like what the English cluster **hl would sound like) and is written as ll in Welsh.
A voiceless postalveolar fricative is a type of consonantal sound used in some spoken languages.The International Phonetic Association uses the term voiceless postalveolar fricative only for the sound [ ʃ ], [1] but it also describes the voiceless postalveolar non-sibilant fricative [ɹ̠̊˔], for which there are significant perceptual differences.
IEEE Recommended Practice for Speech Quality Measurements [3] sets out seventy-two lists of ten phrases each, described as the "1965 Revised List of Phonetically Balanced Sentences (Harvard Sentences)." They are widely used in research on telecommunications, speech, and acoustics, where standardized and repeatable sequences of speech are needed.
