Phonotactics (in Greek phone = voice and tactic = course) is a branch of phonology that deals with restrictions in a language on the permissible combinations of phonemes. Greek (el ελληνική γλώσσα or simply el ελληνικά — "Hellenic" is an Indo-European language, spoken today by 15-22 million people mainly Phonology ( Greek φωνή (phōnē voice sound + λόγος (lógos word speech subject of discussion is the systematic use of sound to encode meaning A language is a dynamic set of visual auditory or tactile Symbols of Communication and the elements used to manipulate them The phoneME project is Sun Microsystems reference implementation of Java virtual machine and associated libraries of Java ME with source licensed under the GNU Phonotactics defines permissible syllable structure, consonant clusters, and vowel sequences by means of phonotactical constraints. A syllable ( Greek:) is a unit of organization for a sequence of speech sounds In Linguistics, a consonant cluster (or consonant blend) is a group of Consonants which have no intervening Vowel. In Phonetics, a vowel is a Sound in spoken Language, such as English ah! or oh!, pronounced with an open Vocal tract
Phonotactic constraints are language specific. For example, in Japanese, consonant clusters like /st/ are not allowed, although they are in English. is a language spoken by over 130 million people in Japan and in Japanese emigrant communities English is a West Germanic language originating in England and is the First language for most people in the United Kingdom, the United States Similarly, the sounds /kn/ and /ɡn/ are not permitted at the beginning of a word in Modern English but are in German and Dutch. The German language (de ''Deutsch'') is a West Germanic language and one of the world's major languages. Dutch ( is a West Germanic language spoken by around 24 million people 22 million of which are from the Netherlands, Belgium and Suriname
Syllables have the following internal segmental structure:
Both onset and coda may be empty, forming a vowel-only syllable, or alternatively, the nucleus can be occupied by a syllabic consonant. In Phonetics and Phonology, a syllable onset is the part of a Syllable that precedes the Syllable nucleus. In the study of Phonology in Linguistics, the rime or rhyme of a Syllable consists of a nucleus and an optional coda In Phonology, a syllable coda comprises the Consonant sounds of a Syllable that follow the nucleus, which is usually a Vowel A syllabic consonant is a Consonant which either forms a Syllable of its own or is the nucleus of a syllable
English phonotactics
The English syllable (and word) twelfths /twɛlfθs/ is divided into the onset /tw/, the nucleus /ɛ/, and the coda /lfθs/, and it can thus be described as CCVCCCC (C = consonant, V = vowel). English phonology is the study of the Phonology (ie the sound system of the English language. On this basis it is possible to form rules for which representations of phoneme classes may fill the cluster. For instance, English allows at most three consonants in an onset, but among native words under standard accents, phonemes in a three-consonantal onset are limited to the following scheme:[1]
- /s/ + pulmonic + approximant:
- /s/ + /m/ + /j/
- /s/ + /t/ + /j ɹ/
- /s/ + /p/ + /j ɹ l/
- /s/ + /k/ + /j ɹ l w/
This constraint can be observed in the pronunciation of the word blue: originally, the vowel of blue was identical to the vowel of cue, approximately [iw]. In human speech pulmonic sounds are those sounds created by the lungs Approximants are speech sounds ( Phonemes) that could be regarded as intermediate between Vowels and typical Consonants In the articulation of approximants In most dialects of English, [iw] shifted to [juː]. Theoretically, this would produce **[bljuː]. The cluster [blj], however, infringes the constraint for three-consonantal onsets in English. Therefore, the pronunciation has been reduced to [bluː] by elision of the [j]. Elision is the omission of one or more sounds (such as a Vowel, a Consonant, or a whole Syllable) in a word or phrase producing a result that is easier
Other languages don't share the same constraint: compare Spanish pliegue [ˈpljeɣe] or French pluie [plɥi]. French ( français,) is a Romance language spoken around the world by 118 million people as a native language and by about 180 to 260 million people
Sonority hierarchy
In general, the rules of phonotactics operate around the sonority hierarchy, stipulating that the nucleus has maximal sonority and that sonority decreases as you move away from the nucleus. A sonority hierarchy or sonority scale is a ranking of speech Sounds (or Phones by amplitude The voiceless alveolar fricative [s] is lower on the sonority hierarchy than the alveolar lateral approximant [l], so the combination /sl/ is permitted in onsets and /ls/ is permitted in codas, but /ls/ is not allowed in onsets and /sl/ is not allowed in codas. The voiceless alveolar fricatives are Consonantal sounds The symbol in the International Phonetic Alphabet that represents these sounds depends on whether a The alveolar lateral approximant is a type of Consonantal sound used in some spoken Languages The symbol in the International Phonetic Alphabet that represents Hence slips /slɪps/ and pulse /pʌls/ are possible English words while *lsips and *pusl are not. There are of course exceptions to this rule, but in general it holds for the phonotactics of most languages.
