Production of speech

Speech production and Linguistics Speech production is a multi-step process by which thoughts are generated into spoken utterances. Production involves the selection of appropriate words and the appropriate form of those words from the lexicon and morphology, and the organization of those words through the syntax.

Then, the phonetic properties of the words are retrieved and the sentence is uttered through the articulations associated with those phonetic properties. Speech sounds are categorized by manner of articulation and place of articulation.

Place of articulation refers to where the airstream in the mouth is constricted. Manner of articulation refers to the manner in which the speech organs interact, such as how closely the air is restricted, what form of airstream is used e.

Production of speech

For any place of articulationthere may be several manners of articulation, and therefore several homorganic consonants. Normal human speech Production of speech pulmonic, produced with pressure Production of speech the lungswhich creates phonation in the glottis in the larynxwhich is then modified by the vocal tract and mouth into different vowels and consonants.

However humans can pronounce words without the use of the lungs and glottis in alaryngeal speechof which there are three types: Speech error Speech production is a complex activity, and as a consequence errors are common, especially in children.

Speech errors come in many forms and are often used to provide evidence to support hypotheses about the nature of speech.

For example, the fact that children often make the error of over-regularizing the -ed past tense suffix in English e.

Speech perception Speech perception refers to the processes by which humans can interpret and understand the sounds used in language. The study of speech perception is closely linked to the fields of phonetics and phonology in linguistics and cognitive psychology and perception in psychology.

Research in speech perception seeks to understand how listeners recognize speech sounds and use this information to understand spoken language.

Research into speech perception also has applications in building computer systems that can recognize speechas well as improving speech recognition for hearing- and language-impaired listeners.

People are more likely to be able to hear differences in sounds across categorical boundaries than within them. A good example of this is voice onset time VOT. Speech repetition In speech repetition, speech being heard is quickly turned from sensory input into motor instructions needed for its immediate or delayed vocal imitation in phonological memory.

This type of mapping plays a key role in enabling children to expand their spoken vocabulary. Masur found that how often children repeat novel words versus those they already have in their lexicon is related to the size of their lexicon later on, with young children who repeat more novel words having a larger lexicon later in development.

Speech repetition could help facilitate the acquisition of this larger lexicon. Speech-language pathology There are several organic and psychological factors that can affect speech. Diseases and disorders of the lungs or the vocal cordsincluding paralysisrespiratory infections bronchitisvocal fold nodules and cancers of the lungs and throat.

Diseases and disorders of the brainincluding alogiaaphasiasdysarthriadystonia and speech processing disorders, where impaired motor planningnerve transmission, phonological processing or perception of the message as opposed to the actual sound leads to poor speech production.

Articulatory problems, such as slurred speechstutteringlispingcleft palateataxiaor nerve damage leading to problems in articulation. Tourette syndrome and tics can also affect speech.Speech: Speech, human communication through spoken language.

Although many animals possess voices of various types and inflectional capabilities, human beings have learned to modulate their voices by articulating the laryngeal tones into audible oral speech.
