Speech disabilities include difficulty producing speech that is recognizable by others or by voice recognition software. For instance, the loudness or clarity of someone's voice might be difficult to understand.

More about speech disabilities

People with speech disabilities encounter barriers with voice-based services, such as automated web-based hotlines and web applications that are operated using voice commands. To use services that rely on voice, people with speech disabilities need alternative modes for interaction such as a text-based chat to interact with hotline representatives or keyboard commands to operate web applications. Also, websites that provide telephone numbers as the only means of communicating with an organizations pose barriers for people with speech disabilities. Alternative means of communication include e-mail and feedback forms.

Examples of speech disabilities

  • Apraxia of speech (AOS) - includes inconsistent articulation and production of speech sounds, and errors producing sounds in the correct order so that spoken words or phrases become difficult to understand.
  • Cluttering (also called "tachyphemia") - includes increased speaking rate, incorrect rhythm, intonation, and co-articulation of sounds, and other influency in speech that is sometimes similar to stuttering.
  • Dysarthria - involves weakness or complete paralysis of muscles that are necessary to produce speech, including lips, lungs, throat, tongue, and others.
  • Speech sound disorder - involves difficulty or inability to produce certain sounds or patterns of sound and sometimes results in addition, distortion, omission, or substitution of such sounds with others.
  • Stuttering - includes influency in speech, repetition of individual sounds or entire words and phrases, and misplacement or prolongation of pauses and sounds during speech that is different from cluttering.
  • Muteness (also called "mutism") - involves inability to speak due to different reasons such as anxiety, brain injuries, or inability to hear and learn speech.
