Speech-Generating Devices (SGDs), also known as voice output communication aids, play an important role in health and social care, particularly for individuals who have difficulties communicating verbally. These devices assist users in expressing their needs, preferences, and thoughts, thereby enhancing their quality of life and enabling more effective interactions with carers, health professionals, and the wider community.
This guide explores the significance, types, functions, and considerations associated with SGDs in health and social care.
What are Speech-Generating Devices (SGDs)?
SGDs are electronic devices designed to help individuals with speech impairments to communicate through synthetic or pre-recorded speech. These devices translate text or symbolic inputs into spoken words, providing users with a voice when their natural speech is limited or non-existent.
Who Benefits from SGDs?
SGDs are beneficial for a wide range of individuals, including those with:
- Neurological conditions: Such as cerebral palsy, amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS), and Parkinson’s disease.
- Developmental disorders: Including autism spectrum disorders (ASD) and Down syndrome.
- Speech and language disorders: Such as apraxia of speech, dysarthria, and aphasia resulting from stroke or brain injury.
- Temporary speech impairments: For instance, those recovering from surgery affecting the vocal cords.
Types of Speech-Generating Devices
There is a variety of SGDs available, differing in functionality, complexity, and suitability for different users. The main types include:
Dedicated Devices
These are standalone devices designed exclusively for communication. They often cater to users with high or complex communication needs and are equipped with advanced software tailored for different levels of cognitive and physical abilities.

These devices offer high-tech features, including dynamic displays, touchscreens, eye-tracking technology, and access to extensive vocabularies. They are intended for users who require more comprehensive and flexible communication options.
Features of Speech-Generating Devices
SGDs come with various features that enhance their usability and effectiveness. Key features include:
Speech Output
The primary function of an SGD is to convert text or symbols into spoken language. Speech output can be either:
- Synthetic Voice: Computer-generated speech that can be personalised to match the user’s preferences regarding accent, tone, and speed.
- Digitised Voice: Pre-recorded human speech that can be played back. This is often used for common phrases or messages.
Input Methods
Users can interact with SGDs through various input methods, including:
- Touchscreens: Users select words, symbols, or letters directly on the display.
- Keypads or Keyboards: Physical or on-screen keyboards allow text input.
- Eye-Tracking and Head-Tracking: For users with limited mobility, these methods enable control through eye or head movement.
- Switches: External buttons or pressure pads that can be adapted for individuals with severe physical impairments.
Vocabulary Options
SGDs can store a wide array of vocabulary items, ranging from basic to extensive word banks. This ensures that users have access to the words and phrases they need for effective communication.
Customisability
Many SGDs offer customisation options, allowing users and carers to tailor the device to suit individual preferences and needs. This may include adjusting voice settings, creating personalised vocabulary lists, and modifying the interface for ease of use.
Portability
SGDs vary in size and weight, with some designed for portability to allow users to communicate on the go. Portable SGDs may include carry handles, straps, or compact sizes for easy transportation.
Selection and Assessment Process
Choosing the right SGD is a critical step in ensuring its effectiveness. The selection process typically involves a comprehensive assessment by speech and language therapists, in collaboration with other health professionals, the user, and their family or carers.
Needs Assessment
An in-depth assessment identifies the user’s communication needs, physical abilities, cognitive skills, and personal preferences. This assessment may involve:
- Observation and Interaction: Understanding how the user currently communicates and their challenges.
- Trials with Different Devices: Allowing the user to try various devices to ascertain which one meets their needs best.
- Family and Caregiver Input: Incorporating insights from those who support the user daily.
Funding and Access
In the UK, SGDs may be funded through various channels, including the NHS, education services, charities, and personal budgets. Health and social care professionals can assist with navigating funding options and securing the necessary resources.
Training and Support
Effective use of an SGD requires training for the user and their support network. This training may include:
Initial Training
After acquiring the device, initial training focuses on familiarising the user and carers with its functions, basic operations, and maintenance.
