Suprasegmentals, otherwise known as prosody can serve a linguistic function such as to affect the meaning of a phrase or word. This can also relate to a paralinguistic function such as to modify or enrich the meaning of spoken information (conveying emotion). Suprasegmentals include rhythm, stress, lexical and grammatical tones,

The IPA chart depicts vowels on the vowel quadrilateral with the shape and, in particular, the corners of the quadrilateral resembling the general relationship of the tongue position during the vowel productions [a], [i]. [o], [u]. Vowels can be described about advancement, tongue height, tenseness, rounding, length, and nasality. In

Small letter shaped symbols, or other types of marks that can be added to a vowel or consonant symbol to modify or refine its meaning are known as diacritics. The IPA chart contains 31 diacritic symbols. In the General American English, a common diacritic is the rhoticity diacritic /˞/ that

Non-pulmonic consonants are clicks, ejectives, and implosives that though not used in English are present in other languages. Children who have hearing loss have been reported as using ejectives, and those with SSD have been reported as using clicks.

Pulmonic constants constitute the majority of consonants produced by speakers when air is expelled from the lungs when articulated. On the IPA chart, pulmonic consonants are well organized concerning the absence or presence of voicing and the place of articulation and manner (how the consonant is articulated). Across the English

The International Phonetic Alphabet, otherwise known as IPA, began in 1886 and is considered the universal symbol system used for transcribing consonants (non-pulmonic and pulmonic), suprasegmental features, and vowels, diacritics that are evident in speakers across the word, and tones and accents.

Linguists and phoneticians use systematic transcription as a form of documentation for typical, common, or standard realizations of speech. This form of transcription may be phonetic (capturing allophonic variations or phenomes in a language) or phonemic (capturing the phenomes in a language) in nature. Phonemic transcription is written within slashes

The motor speech disorder that involves difficulty with the sensorimotor control processes is called childhood dysarthria. Childhood dysarthria is involved in the production of speech, typically that of motor programming and execution. This can be a result of a neurological condition (neurofibromatosis), traumatic brain injury, or neurological impairment during or

Childhood apraxia of speech is a motor speech disorder that involves issues with planning and programming of movement sequences that result in dysprosody and speech sound production errors. When compared to phonological impairment, childhood apraxia is quite rare as it occurs in about 1 to 2 children per one thousand.

`Inconsistent speech disorder, which is also known as inconsistent phonological disorder, is less common than phonological impairment. This disorder is characterized by inconsistent productions of the same word items (lexical) and is aligned with phonological assembly difficulty including difficulty with selecting and sequencing phenomes, without the accompaniment of oromotor difficulties.
