Centre for Augmentative and Alternative Communication

Centre for Augmentative and Alternative Communication We focus on research, education and advocacy in Augmentative and Alternative Communication (AAC) What do we do?

The Centre for AAC at the University of Pretoria aims to provide research and training to improve the lives of persons with severe communication disabilities and their families. The Centre for Augmentative and Alternative Communication was founded in 1990 by Prof Erna Alant in conjunction with Prof Lyle Lloyd from the USA. The impetus to start the Centre came from concerned parents requesting better and more coordinated service delivery for their children with severe disabilities and little or no functional speech. The activities of the Centre quickly expanded from direct service delivery to training and education through degree and non-degree courses. Research was also added to provide evidence-based services appropriate to the South African context, and to mobilise support for persons with little or no functional speech by providing credible evidence of the challenges they face. Today the Centre functions as a postgraduate educational entity at the University of Pretoria, while also maintaining the status of a non-profit organisation, owing to various community projects and commitments. Most of the CAAC main activities are focussed on research, teaching and training is the fields of Augmentative and Alternative Communication and Early Childhood Intervention. The training are conducted in various settings including preschool, primary and secondary levels as well as other institutions and health care settings to support inclusion of children and adults with severe disabilities into the educational, health and employment context. Activities focus on training as well as material and technology development to support inclusion of children and adults with severe communication disabilities into communities. Training

In the over 30 years of the existence of the CAAC, staff has trained over 10 000 persons who use AAC, parents, teachers, and therapists in enhancing communication with individuals with severe disabilities. Follow-up visits to contexts confirmed that the CAAC has reached over eight thousand children, youth, and adults through training of families, community leaders and other professionals. Activities include training in communities as well as five post-graduate programs in the fields of early childhood intervention, severe disabilities and AAC. Leadership and advocacy

The CAAC recently embarked on a national project to assist youth with severe disabilities in getting access to communication and information technology, called the Fofa Project. This project assists young people to "speak for themselves" and facilitate their access to employment. Research

The CAAC staff and students are engaged on an ongoing basis in research in the fields of AAC, severe disabilities and early childhood intervention.

The Centre for AAC was honoured to welcome Prof Erna Alant, founder of the Centre for AAC, for her recent talk “Making-Meaning Across a Lifetime: Personal and Professional Reflections” on March 27th.

Her presentation invited us to think about meaning‑making not as an abstract concept, but as a deeply human process - being with ourselves and doing with others, engaging in the everyday activities that shape who we are becoming.

One of the most powerful moments was the case study of an adult with severe disabilities. Through this story, Prof Alant highlighted the elements that help us navigate change and create meaning across the lifespan. Many of us felt these insights resonate with our own professional and personal journeys. They reminded us that intimacy and trust shift over time, and that it is important to meet those transitions with openness and care.

We are deeply grateful for the wisdom and gentle reminders Prof Alant shared. Meaning is something we co‑create, moment by moment, in relationship with others. 🌿

✨ Celebrating inclusive learning at UP✨

In March, Ms Constance Ntuli, Disability Advocate at the Centre for AAC, did a presentation to the Occupational Therapy students at the University of Pretoria.

Constance shared how she uses Speech Assistant AAC, an app on her phone, to communicate in her daily life, highlighting the power of AAC in supporting independence and meaningful participation.

The students asked thoughtful questions and left with a deeper understanding of the real-world impact of AAC across home, community, and workplace settings.

A huge thank‑you to Constance for her leadership in disability advocacy. Her story continues to inspire future clinicians to think inclusively about communication support.

🌟Welcoming the next generation of communication professionals🌟

The Centre for AAC recently hosted final year Speech Language Pathology and Audiology students from Sefako Makgatho University for an immersive introduction to AAC technology.

The day kicked off with a warm welcome and an engaging overview of AAC by Prof Kerstin Tonsing and Ms Constance Ntuli, followed by hands-on demonstrations where students explored high-tech communication solutions. They had the chance to try out various devices, ask questions, and dive into thoughtful discussions about the benefits, challenges, and real-world applications of AAC.

A highlight for many was hearing from Ms Constance Ntuli, Disability Advocate at the CAAC, who shared how she uses the Speech Assistant AAC app to communicate confidently at home, at work, and in social spaces. Her insights brought the power and impact of AAC to life.

We are inspired by these future professionals and excited to see how they will champion inclusive communication in their careers.

As part of the Mitacs Globalink Research Award, the Centre for AAC had the pleasure of hosting Ms Saba Sadeghi, a PhD candidate in Rehabilitation Sciences from the University of Ottawa, Canada.

She immersed herself in academic life at the Centre for AAC, engaging with our Masters and PhD students, attending workshops, joining field visits, and building meaningful collaborations with students, clinicians, and community partners.

Saba further shared her expertise through guest lectures for CAAC students and for students in the Department of Speech Therapy and Audiology at Sefako Makgatho Health Sciences University.

During her visit, Saba contributed to an inclusive research project food and nutrition security for children with disabilities in Gauteng schools, with Prof Shakila Dada.

We are grateful for her contributions and the global perspectives she brought to our community.

Today, on Human Rights Day, we honour the principle that every person deserves dignity, equality and the freedom to participate fully in society. For people who use AAC, this begins with one essential truth:

✨Communication is a human right ✨

As we reflect on our country’s history and the ongoing work of building an inclusive South Africa, we recommit to creating environments where all forms of communication are respected and supported. When we uphold communication rights, we uphold human rights.

🔊Every voice matters
🔊Every voice counts

Let’s continue building a society where everyone can be heard and understood.

🔊 How can you bring the Communication Bill of Rights into everyday spaces?

The Communication Bill of Rights becomes powerful when it moves off the page and into daily practice. In schools, hospitals, clinics, and community settings, people who use AAC deserve environments that honour their right to be heard, to choose, to refuse, and to participate fully. These rights can be embedded in everyday routines with small, intentional shifts.

🏫 When communication rights are upheld, learners are not ‘included,’ they belong.

🏥 Honouring communication rights in healthcare is essential for safety, consent and dignity.

🏘️Communication rights ensure that people are not spoken for; they are heard.

📖 Reinforcing agency and self-advocacy with shared book reading📖

This week, we are focusing on the Communication Bill of Rights and how it reinforces communication as a fundamental human right.

Every child has the right to communicate their choices, needs, and preferences.

A simple way to nurture agency and self-advocacy is through shared reading activities.

📖 Using the book ‘I can dress myself!’ by Heidel Dedekind, Bridget Krone and Nontobeko Kunene, a free online book from bookdash.org, here are some ideas:

- Add speech bubbles with the phrase “I can” alongside illustrations
- Reinforce with symbols or visuals to support understanding
- Pause during reading to let children point, sign, or say “I can” when they recognise an action they can do
- Celebrate their response. This models self-advocacy and builds confidence in expressing independence

By embedding “I can” into the reading, children practice agency (making choices) and self-advocacy (expressing their abilities).

This transforms story time into a powerful tool for communication rights and personal empowerment.

The Centre for AAC sends heartfelt wishes to everyone celebrating Eid‑ul‑Fitr. This special day is a reminder of gratitude, connection and the joy of sharing. For many people with communication disabilities, expressing the excitement of Eid can be difficult. To support fuller participation in the celebrations, we have created a free, easy‑to‑use communication board.

The Communication Bill of Rights sets the baseline for what meaningful communication must look like. It reminds practitioners, families, educators and policymakers that AAC is not about technology; it is about access, autonomy, and dignity. Many AAC users still face barriers to being heard, understood, and included.

The Communication Bill of Rights reminds us that everyone has the right to participate fully in family life, school, community, culture, and play.
Inclusion is not about ‘helping’ someone join in. It’s about removing barriers so they can take their rightful place.
