Since speech, as with most forms of communication, is learned through observation (hearing other people talk) and imitation (repeating what you have heard), many deaf people, especially those born deaf or deafened at an early age, have difficulty learning to speak with the natural cadence and intonation of those blessed with hearing. Speech therapists and speech pathologists are often needed to help deaf and hard of hearing people improve their speech capabilities. The learning and communication tools and skills used by deaf people can be very useful for speech therapists. Many techniques and technologies that have been developed for those with hearing loss, such as American Sign Language, Cochlear Implants, Closed Captioning, video chat, and ASL enabled mobile communication apps, can be of great use to speech pathologists throughout their careers. These sites have great information for speech therapists, those looking to study speech therapy, and even individuals seeking speech therapy or another type of communication therapy or coaching.
