Tadoma is a method of communication utilized by deafblind individuals, in which the listener places their little finger on the speaker's lips and their fingers along the jawline. The middle three fingers often fall along the speaker's cheeks with the little finger picking up the vibrations of the speaker's throat. It is sometimes referred to as tactile lipreading, as the listener feels the movement of the lips, the vibrations of the vocal cords, expansion of the cheeks and the warm air produced by nasal phonemes such as 'N' and 'M'. Hand positioning can vary, and it is a sometimes also used by hard-of-hearing people to supplement their remaining hearing.
Telephony is the field of technology involving the development, application, and deployment of telecommunications services for the purpose of electronic transmission of voice, fax, or data, between distant parties. The history of telephony is intimately linked to the invention and development of the telephone.
Speech disorders, impairments, or impediments, are a type of communication disorder in which normal speech is disrupted. This can mean fluency disorders like stuttering, cluttering or lisps. Someone who is unable to speak due to a speech disorder is considered mute. Speech skills are vital to social relationships and learning, and delays or disorders that relate to developing these skills can impact individuals function. For many children and adolescents, this can present as issues with academics. Speech disorders affect roughly 11.5% of the US population, and 5% of the primary school population. Speech is a complex process that requires precise timing, nerve and muscle control, and as a result is susceptible to impairments. A person who has a stroke, an accident or birth defect may have speech and language problems.
Facilitated communication (FC), or supported typing, is a scientifically discredited technique, which claims to allow non-verbal people, such as those with autism, to communicate. The technique involves a facilitator guiding the disabled person's arm or hand in an attempt to help them type on a keyboard or other such device which they are unable to properly use if unfacilitated.
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 some speech information from sight of the moving mouth.
Communication access realtime translation (CART), also called open captioning or realtime stenography or simply realtime captioning, is the general name of the system that stenographers and others use to convert speech to text. A trained operator writes the exact words spoken using a special phonetic keyboard, or stenography methods, relaying a reliable and accurate translation that is broadcast to the recipient on a screen, laptop, or other device. CART professionals have qualifications for added expertise (speed and accuracy) as compared to court reporters and other stenographers.
A telecommunications relay service, also known as TRS, relay service, or IP-relay, or Web-based relay service, is an operator service that allows people who are deaf, hard of hearing, deafblind, or have a speech disorder to place calls to standard telephone users via a keyboard or assistive device. Originally, relay services were designed to be connected through a TDD, teletypewriter (TTY) or other assistive telephone device. Services gradually have expanded to include almost any real-time text capable technology such as a personal computer, laptop, mobile phone, PDA, and many other devices. The first TTY was invented by deaf scientist Robert Weitbrecht in 1964. The first relay service was established in 1974 by Converse Communications of Connecticut.
Nonverbal communication is the transmission of messages or signals through a nonverbal platform such as eye contact (oculesics), body language (kinesics), social distance (proxemics), touch (haptics), voice, physical environments/appearance, and use of objects. When communicating, we utilize nonverbal channels as means to convey different messages or signals, whereas others can interpret these message. The study of nonverbal communication started in 1872 with the publication of The Expression of the Emotions in Man and Animals by Charles Darwin. Darwin began to study nonverbal communication as he noticed the interactions between animals such as lions, tigers, dogs etc. and realized they also communicated by gestures and expressions. For the first time, nonverbal communication was studied and its relevance noted. Today, scholars argue that nonverbal communication can convey more meaning than verbal communication.
Unconsciouscommunication is the subtle, unintentional, unconscious cues that provide information to another individual. It can be verbal or it can be non-verbal. Some psychologists instead use the term honest signals because such cues are involuntary behaviors that often convey emotion whereas body language can be controlled. Many decisions are based on unconscious communication, which is interpreted and created in the right hemisphere of the brain. The right hemisphere is dominant in perceiving and expressing body language, facial expressions, verbal cues, and other indications that have to do with emotion but it does not exclusively deal with the unconscious.
Augmentative and alternative communication (AAC) encompasses the communication methods used to supplement or replace speech or writing for those with impairments in the production or comprehension of spoken or written language. AAC is used by those with a wide range of speech and language impairments, including congenital impairments such as cerebral palsy, intellectual impairment and autism, and acquired conditions such as amyotrophic lateral sclerosis and Parkinson's disease. AAC can be a permanent addition to a person's communication or a temporary aid. Stephen Hawking, probably the best-known user of AAC, had amyotrophic lateral sclerosis, and communicated through a speech-generating device.
STS relay is the speech-to-speech relay service available to any telephone callers or callees with speech disability and to those who wish to talk with them.
A video relay service (VRS), also sometimes known as a video interpreting service (VIS), is a video telecommunication service that allows deaf, hard-of-hearing, and speech-impaired (D-HOH-SI) individuals to communicate over video telephones and similar technologies with hearing people in real-time, via a sign language interpreter.
Speech perception is the process by which the sounds of language are heard, interpreted, and understood. The study of speech perception is closely linked to the fields of phonology and phonetics in linguistics and cognitive psychology and perception in psychology. Research in speech perception seeks to understand how human listeners recognize speech sounds and use this information to understand spoken language. Speech perception research has applications in building computer systems that can recognize speech, in improving speech recognition for hearing- and language-impaired listeners, and in foreign-language teaching.
Speech-generating devices (SGDs), also known as voice output communication aids, are electronic augmentative and alternative communication (AAC) systems used to supplement or replace speech or writing for individuals with severe speech impairments, enabling them to verbally communicate. SGDs are important for people who have limited means of interacting verbally, as they allow individuals to become active participants in communication interactions. They are particularly helpful for patients with amyotrophic lateral sclerosis (ALS) but recently have been used for children with predicted speech deficiencies.
Aural rehabilitation is the process of identifying and diagnosing a hearing loss, providing different types of therapies to clients who are hard of hearing, and implementing different amplification devices to aid the client's hearing abilities. Aural rehab includes specific procedures in which each therapy and amplification device has as its goal the habilitation or rehabilitation of persons to overcome the handicap (disability) caused by a hearing impairment or deafness.
Speech and language impairment are basic categories that might be drawn in issues of communication involve hearing, speech, language, and fluency.
Social cues are verbal or non-verbal signals expressed through the face, body, voice, motion and guide conversations as well as other social interactions by influencing our impressions of and responses to others. These percepts are important communicative tools as they convey important social and contextual information and therefore facilitate social understanding.
Forensic speechreading is the use of speechreading for information or evidential purposes. Forensic speechreading can be considered a branch of forensic linguistics. In contrast to speaker recognition, which is often the focus of voice analysis from an audio record, forensic speechreading usually aims to establish the content of speech, since the identity of the speaker is usually apparent. Often, it involves the production of a transcript of lip-read video-recordings of talk that lack a usable audiotrack, for example CCTV material. Occasionally, 'live' lipreading is involved, for example in the Casey Anthony case. Forensic speechreaders are usually deaf or from deaf families (CODA), and use speechreading in their daily lives to a greater extent than people with normal hearing outside the deaf community. Some speechreading tests suggest deaf people can be better lipreaders than most hearing people.
Assistive Technology for the Deaf and Hard of Hearing is technology built to assist those who are deaf or suffer from hearing loss. Examples of such technology include hearing aids, video relay services, tactile devices, alerting devices and technology for supporting communication.
Harriet Burbank Rogers was an American educator, a pioneer in the oral method of instruction of the deaf. She was the first director of Clarke School for the Deaf, the first U.S. institution to teach the deaf by articulation and lip reading rather than by signing. Her advocacy for oralist instruction children increased utilization of oral-only communication models in many American schools.
