Speech Generating Devices (SGDs) are computerised devices that produce speech sounds (such as words or noises) for the individual through the device. 

There are a variety of different types of SGDs available to individuals including:

• Tablets or iPads

  • These are fitted with an application that contains icons that the individual or their communication partner can select.

  • The device will then produce a speech sound or vocalisation based on the icon that has been selected.

SGDs are a common form of aided High-Tech AAC system used by individuals with many different types of CCN. 

SGDs are able to be modified to fit the needs of the individual as are options to make modifications to elements such as: 

• Vocabulary choice

• Display and Layout

• Language

• Method of interaction (e.g. pressing button with hands or other body part, using eye tracking to select etc.)

SGDs have been shown to be a good option for individuals who have very limited (or no) verbal usage but who have a good level of understanding when spoken to (i.e. their receptive language is stronger than their expressive language). 

This can include but is not limted to:

• Non-verbal individuals with ASD

• Individuals who have differences in the physical development of the mouth that influences their ability to form words.
