Lip Reading
Lip reading, also known as speechreading, is a technique of understanding a limited range of speech by visually interpreting the movements of the lips, face and tongue without sound. Estimates of the range of lip reading vary, with some figures as low as 30% because lip reading relies on context, language knowledge, and any residual hearing. Although lip reading is used most extensively by deaf and hard-of-hearing people, most people with normal hearing process can infer some speech information by observing a speaker's mouth. Process Although speech perception is considered to be an auditory skill, it is intrinsically multimodal, since producing speech requires the speaker to make movements of the lips, teeth and tongue which are often visible in face-to-face communication. Information from the lips and face supports aural comprehension and most fluent listeners of a language are sensitive to seen speech actions (see McGurk effect). The extent to which people make use of seen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Speech
Speech is the use of the human voice as a medium for language. Spoken language combines vowel and consonant sounds to form units of meaning like words, which belong to a language's lexicon. There are many different intentional speech acts, such as informing, declaring, asking, persuading, directing; acts may vary in various aspects like enunciation, Intonation (linguistics), intonation, loudness, and Speech tempo, tempo to convey meaning. Individuals may also unintentionally communicate aspects of their social position through speech, such as sex, age, place of origin, physiological and mental condition, education, and experiences. While normally used to facilitate communication with others, people may also use speech without the intent to communicate. Speech may nevertheless express emotions or desires; people Talking to oneself, talk to themselves sometimes in acts that are a development of what some psychologists (e.g., Lev Vygotsky) have maintained is the use of silent spee ...

Phonology
Phonology (formerly also phonemics or phonematics: "phonemics ''n.'' [''obsolescent''] 1. Any procedure for identifying the phonemes of a language from a corpus of data. 2. (formerly also phonematics) A former synonym for phonology, often preferred by the American Structuralists and reflecting the importance in structuralist work of phonemics in sense 1.": "phonematics ''n.'' 1. [''obsolete''] An old synonym for phonemics (sense 2).") is the branch of linguistics that studies how languages systematically organize their phonemes or, for sign languages, their constituent parts of signs. The term can also refer specifically to the sound or sign system of a particular language variety. At one time, the study of phonology related only to the study of the systems of phonemes in spoken languages, but now it may relate to any Linguistic description, linguistic analysis either: Sign languages have a phonological system equivalent to the system of sounds in spoken languages.

Bimodal Bilingualism
Bimodal bilingualism is an individual or community's bilingual competency in at least one oral language and at least one sign language, which utilize two different modalities. An oral language consists of a vocal-aural modality versus a signed language which consists of a visual-spatial modality. A substantial number of bimodal bilinguals are children of deaf adults (CODA) or other hearing people who learn sign language for various reasons. Deaf people as a group have their own sign language(s) and culture that is referred to as Deaf, but invariably live within a larger hearing culture with its own oral language. Thus, "most deaf people are bilingual to some extent in n orallanguage in some form". In discussions of multilingualism in the United States, bimodal bilingualism and bimodal bilinguals have often not been mentioned or even considered. This is in part because American Sign Language, the predominant sign language used in the U.S., only began to be acknowledged as a natural ...

Sign Language
Sign languages (also known as signed languages) are languages that use the visual-manual modality to convey meaning, instead of spoken words. Sign languages are expressed through manual articulation in combination with #Non-manual elements, non-manual markers. Sign languages are full-fledged natural languages with their own grammar and lexicon. Sign languages are not universal and are usually not mutual intelligibility, mutually intelligible, although there are similarities among different sign languages. Linguists consider both spoken and signed communication to be types of natural language, meaning that both emerged through an abstract, protracted aging process and evolved over time without meticulous planning. This is supported by the fact that there is substantial overlap between the neural substrates of sign and spoken language processing, despite the obvious differences in modality. Sign language should not be confused with body language, a type of non verbal communicati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Oralism
Oralism is the education of deaf students through oral language by using lip reading, speech, and mimicking the mouth shapes and breathing patterns of speech.Through Deaf Eyes. Diane Garey, Lawrence R. Hott. DVD, PBS (Direct), 2007. Oralism came into popular use in the United States around the late 1860s. In 1867, the Clarke School for the Deaf in Northampton, Massachusetts, was the first school to start teaching in this manner. Oralism and its contrast, manualism, manifest differently in deaf education and are a source of controversy for involved communities. Listening and Spoken Language, a technique for teaching deaf children that emphasizes the child's perception of auditory signals from hearing aids or cochlear implants, is how oralism continues on in the current day. History 16th and 17th century Fray Pedro Ponce de León (1520–1584) is often credited as the inventor of deaf education. Later, Juan Pablo Bonet (–1633) published ''Reducción de las letras y ar ...

Second International Congress On Education Of The Deaf
The Second International Congress on Education of the Deaf was an international conference of deaf educators held in Milan, Italy in 1880. It is commonly known as the "Milan Conference" or "Milan Congress". This Congress was preceded by the First International Congress in Paris in 1878. Joseph Marius Magnat, a Swiss former oralist, received a significant donation to organize the more well-known Second Congress two years hence. After deliberations from 6 to 11 September 1880, the Milan Conference declared that oral education (oralism) was superior to manual education (sign language) and passed a resolution banning the use of sign language in school. After its passage, various European and American schools largely switched to using speech therapy without sign language as a method of deaf education until the late 1960s and early 1970s, when sign language started to be recognised as the ideal method of deaf education. In 2010, a formal apology was made by the board at the 21st I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Dyslexia
Dyslexia (), previously known as word blindness, is a learning disability that affects either reading or writing. Different people are affected to different degrees. Problems may include difficulties in spelling words, reading quickly, writing words, "sounding out" words in the head, pronouncing words when reading aloud and understanding what one reads. Often these difficulties are first noticed at school. The difficulties are involuntary, and people with this disorder have a normal desire to learn. People with dyslexia have higher rates of attention deficit hyperactivity disorder (ADHD), developmental language disorders, and difficulties with numbers. Dyslexia is believed to be caused by the interaction of genetic and environmental factors. Some cases run in families. Dyslexia that develops due to a traumatic brain injury, stroke, or dementia is sometimes called "acquired dyslexia" or alexia. The underlying mechanisms of dyslexia result from differences within the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Specific Language Impairment
Specific language impairment (SLI) is diagnosed when a child's language does not develop normally and the difficulties cannot be accounted for by generally slow development, physical abnormality of the speech apparatus, autism spectrum disorder, apraxia, acquired brain damage or hearing loss. Twin studies have shown that it is under genetic influence. Although language impairment can result from a single-gene mutation, this is unusual. More commonly SLI results from the combined influence of multiple genetic variants, each of which is found in the general population, as well as environmental influences. Classification Specific language impairment (SLI) is diagnosed when a child has delayed or disordered language development for no apparent reason. Usually the first indication of SLI is that the child is later than usual in starting to speak and subsequently is delayed in putting words together to form sentences. Spoken language may be immature. In many children with SLI, understan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Williams Syndrome
Williams syndrome (WS), also Williams–Beuren syndrome (WBS), is a genetic disorder that affects many parts of the body. Facial features frequently include a broad forehead, underdeveloped chin, short nose, and full cheeks. Mild to moderate intellectual disability is observed, particularly challenges with visual spatial tasks such as drawing. Verbal skills are relatively unaffected. Many people have an outgoing personality, a happy disposition, an openness to engaging with other people, increased empathy and decreased aggression. Medical issues with teeth, heart problems (especially supravalvular aortic stenosis), and periods of hypercalcemia, high blood calcium are common. Williams syndrome is caused by a genetic abnormality, specifically a Deletion (genetics), deletion of about 27 genes from the long arm of one of the two chromosome 7s. Typically, this occurs as a random event during the formation of the egg or sperm from which a person develops. In a small number of cases, i ...

Autism
Autism, also known as autism spectrum disorder (ASD), is a neurodevelopmental disorder characterized by differences or difficulties in social communication and interaction, a preference for predictability and routine, sensory processing differences, focused interests, and repetitive behaviors, which may include stimming. Formal diagnosis requires significant challenges in multiple domains of life, with characteristics that are atypical or more pronounced than expected for one's age and sociocultural context.(World Health Organization: International Classification of Diseases version 11 (ICD-11)): https://icd.who.int/browse/2024-01/mms/en#437815624 Motor coordination difficulties are common but not required for diagnosis. Autism is a spectrum disorder, resulting in wide variations in presentation and support needs, such as that between speaking and non-speaking populations. Increased estimates of autism prevalence since the 1990s are primarily attributed to broader c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Hearing Loss
Hearing loss is a partial or total inability to hear. Hearing loss may be present at birth or acquired at any time afterwards. Hearing loss may occur in one or both ears. In children, hearing problems can affect the ability to acquire spoken language, and in adults it can create difficulties with social interaction and at work. Hearing loss can be temporary or permanent. Hearing loss related to age usually affects both ears and is due to cochlear hair cell loss. In some people, particularly older people, hearing loss can result in loneliness. Hearing loss may be caused by a number of factors, including: genetics, ageing, exposure to noise, some infections, birth complications, trauma to the ear, and certain medications or toxins. A common condition that results in hearing loss is chronic ear infections. Certain infections during pregnancy, such as cytomegalovirus, syphilis and rubella, may also cause hearing loss in the child. Hearing loss is diagnosed when hearing ...
