Which type of AAC device is often used for individuals with speech difficulties?

Speech-generating devices (SGDs) are specialized AAC devices designed to assist individuals who have speech difficulties. They function by producing spoken output based on input from the user, which can come from various methods such as typing, pressing buttons, or selecting symbols. This technology allows users to communicate verbally, providing a voice that may otherwise be inaccessible due to speech impairments.

SGDs can vary widely in complexity, from simple devices that speak single words or phrases to advanced systems that utilize speech synthesis to generate more fluid, natural speech. This adaptability makes them a powerful tool for individuals with diverse communication needs and levels of ability, allowing for a tailored approach to communication.

Other options listed, while beneficial in their own right, do not directly facilitate speech output in the same way as SGDs. Text-to-speech converters, for instance, primarily convert written text into spoken words but may not offer the interactive communication elements that SGDs provide. Simple communication boards allow users to point to symbols or images to convey messages, but they do not generate speech themselves. Writing aids assist with manual writing tasks but do not address speech generation at all. Thus, SGDs are the most appropriate and effective choice for supporting individuals with speech difficulties.
