[8] [172] With improved technology, keyboard communication devices developed in Denmark, the Netherlands and the US increased in portability; the typed messages were displayed on a screen or strip of paper. By the end of the 1970s, communication devices were being commercially produced, and a few, such as the HandiVoice, had voice output. [8]
The use of assistive technology and devices provides this community with various solutions to their problems by providing higher sound (for those who are hard of hearing), tactile feedback, visual cues and improved technology access. Individuals who are deaf or hard of hearing utilize a variety of assistive technologies that provide them with ...
A hearing aid or deaf aid is an electro-acoustic device which is designed to amplify sound for the wearer, usually with the aim of making speech more intelligible, and to correct impaired hearing as measured by audiometry. This type of assistive technology helps people with hearing loss participate more fully in their hearing communities by ...

If a device does create a voice output, it is referred to as a speech generating device. While the message may take the form of speech output, it may also be printed as a visual display of speech. Many of these devices can be connected to a computer, and in some cases, they may even be adapted to produce a variety of different languages. [15] [22]
Electronic fluency devices can be divided into two basic categories: Computerized feedback devices provide feedback on the physiological control of respiration and phonation, including loudness, vocal intensity and breathing patterns. [1] Altered auditory feedback (AAF) devices alter the speech signal so that speakers hear their voices differently.
Partner-assisted scanning is a technique used with children who have severe motor and communication impairments, and especially those with additional visual impairment, those who do not yet have an established alternative form of communication, or who are unable to use their usual method, perhaps because their electronic speech output device is being repaired.
