Speech-Generating Devices for Indian Families
The first time a non-speaking child presses a symbol on a tablet and the device says "I want water" out loud, something shifts in the home. The grandmother who had been doubtful softens. The sibling who had been confused understands. The child realises she has been heard. Speech-generating devices are not magic, but in the right hands they come close.
This article walks Indian families through what these devices actually are, what is available here, what they cost and how to set them up so they actually work.
What speech-generating devices actually do
A speech-generating device, or SGD, is any tool that produces spoken language when a user activates it. The user can be activating buttons, touching symbols on a screen, scanning through options with a switch, or even using eye gaze. The device speaks the chosen words aloud through a speaker.
For most Indian families today, the practical form of an SGD is a tablet, usually an iPad, running a dedicated AAC app. Dedicated standalone devices, often imported, also exist but are less common because of cost and access. The principle is the same regardless of the form: the device gives the child a voice that everyone around her can hear.
SGDs sit at the higher-tech end of the spectrum covered in our broader AAC guide for Indian families. They are not the right starting point for every child, but for many they unlock a level of communication that low-tech alone cannot reach.
Devices and apps available in India
The most commonly used setup in India today is an iPad with one of the major AAC apps. Proloquo2Go and TouchChat with WordPower are the international leaders. Avaz is an Indian-developed AAC app that has done significant work in Indian languages and bilingual setups. LAMP Words for Life is well regarded for motor planning consistency.
Each app has a different philosophy. Some build around core word grids that stay in the same position as vocabulary expands, which supports motor learning. Others organise around folders by topic. Some are picture-heavy, others are symbol-and-text combined. The right choice depends on the child's profile, the SLP's training and the family's daily life.
For families specifically looking at Indian-language support, see our piece on AAC apps that work for Indian languages, which goes deeper into bilingual setups.
Cost, access and funding paths
The real cost of an SGD setup is not just the device. It is the device plus the app plus a sturdy case plus the time of an SLP who can set it up properly plus ongoing family training. A realistic budget for a first year, including these, runs from forty thousand rupees at the leaner end to well above a lakh at the higher end.
Funding paths Indian families use include direct family purchase, contributions from extended family, employer support programmes, NGO grants, donations from community groups and rarely insurance. None of these are easy, but families do find ways. Talking to other AAC families in your city is often the fastest way to learn what worked.
The cost is real, but so is the alternative. A child without a reliable way to communicate is at higher risk of meltdowns, mental health difficulties, learning gaps, social isolation and safety issues. Framing the SGD as a long-term voice tool, similar to how a family would think about glasses or a hearing aid, helps justify the investment.
Setting up the device for daily life
A new SGD often arrives with a generic vocabulary set. The first crucial step, ideally with an SLP, is customising it to the child's life. Adding family names. Adding favourite foods, including the specific Indian dishes the family eats. Adding school subjects, teachers' names, helper's name, pet's name. Adding the words the child needs to say in the home most often.
The home environment around the device matters too. The tablet needs a permanent home, like a hook near the dining table, so it is always available. It needs to be charged nightly so it never runs out. It should be on at all times during waking hours, not put away after "therapy". Volume should be loud enough to be heard across the room.
This kind of integration is exactly what at-home early intervention is built for. A therapist visiting your home can see whether the tablet is genuinely available or quietly being parked in a cupboard.
Training family to use the device
The biggest predictor of SGD success is not the child. It is whether the people around the child use the device themselves to model communication. This is called aided language modelling, and it changes everything.
Modelling means an adult presses symbols on the device while speaking, throughout the day, in ordinary interactions. When you offer water, you press "want" and "water" while saying "do you want water". When the bus passes, you press "look" and "bus". When you finish dinner, you press "all done". The child sees, again and again, how the device is used. Eventually, she tries it herself.
If only the SLP models during a weekly session, the child will not become a fluent user. If parents, grandparents, siblings and helpers all model in small ways across the day, fluency builds within months. Bringing the whole family on board, including grandparents who may be sceptical, is part of the work. There is more on this in our piece on teaching family to use a child's AAC.
Common parent worries answered
Parents often worry that the device will make their child antisocial, that it will replace speech, that other children will mock it, or that they have left it too late. None of these worries is silly. All of them deserve honest answers.
The device does not make a child antisocial. It opens social interactions that were not possible before. A child who could not request, refuse, comment or ask a question can now do all of these. That is more social, not less.
The device does not replace speech. Research consistently shows AAC users develop more speech than matched peers without AAC, not less. We address this in detail in the myth that AAC delays speech.
Other children adapt to AAC much faster than adults do. Once a teacher briefs the class, most children treat the device as normal within days.
And it is rarely too late. Older children and even teenagers have moved into AAC successfully when given the right support. The right time is now.
If you are weighing an SGD for your child and want to talk it through with a Carely SLP who has set up devices in other Indian homes, the Carely at-home therapy team can come home and walk through the decision with you.
Frequently asked questions
Do I need an iPad or will any tablet work?
For the most well-developed AAC apps today, an iPad is the most reliable choice. Android options exist and are improving but the strongest apps still run on iOS. If budget is a constraint, even an older second-hand iPad can work if it runs the required iOS version.
How long until my child starts using the device on her own?
This varies. Some children initiate within weeks of consistent modelling. Others take many months. The single biggest factor is how much the people around the child model. With strong modelling, most children show meaningful independent use within six to twelve months.
What if my child only presses random buttons?
This is normal early exploration and should be welcomed, not blocked. The child is learning that pressing the device produces speech. Over time, with modelling and responsive partners who treat each press as meaningful, the random presses turn into intentional communication.
Should I lock the device so my child cannot access apps and videos?
Yes, generally. Most AAC apps have a guided access or kiosk mode that keeps the device on the AAC app only. This protects the device's purpose as a voice rather than entertainment.
What happens at school?
The device should travel with the child to school. Briefing the teachers, the support staff and ideally the class is part of setup. When schools are involved well, AAC becomes part of the classroom rather than a foreign object.
