Communication and ALS
ALS can make speaking harder. As movement changes, writing, typing or touching a screen may become harder too.
That does not mean communication has to stop. It usually means finding another way to do it.
The simplest rule is: use the easiest way that works.
Speak while speaking works. Write or type when that is easier. If touching a screen becomes difficult, a switch may let you control a communication system with just one reliable movement. Eye gaze, head movement or help from another person can provide other ways to communicate.
You do not need to use all of these. And ALS does not affect everyone in exactly the same way, or in the same order.
It simply helps to know what the options are before you need them.
As communication changes
People often use more than one method.
Speech might work well for short conversations but become tiring later in the day. Writing might be quickest when one word is difficult to understand. A switch might be easier than touch for longer periods.
The aim is not to move from one system to another as quickly as possible.
Keep using whatever makes communication easiest.
Two separate choices
It can help to separate two questions:
- What are you communicating with?
- A piece of paper, a board, an app or a communication device.
- How are you controlling it?
- Touch, typing, a switch, eye movement or another reliable movement.
Sometimes the communication tool can stay the same while only the way you control it changes.
If speech becomes harder to understand
Speech often changes gradually.
Someone who knows you well may still understand something that another person cannot. Context helps too: a familiar sound, expression or attempt at a word may be enough when both people already know what is being discussed.
Keep speaking for as long as speaking is useful to you. When it becomes difficult or tiring, another method can fill the gap.
If writing is comfortable, writing may be the quickest answer. Pen and paper counts. So does a simple writing tablet.
Typing on a phone, tablet or computer can work too. Many devices can speak typed text aloud, and communication apps can do the same.
You do not have to stop speaking because you start using one of these. You can move between speech, writing and a communication device depending on what is easiest at that moment.
If preserving your voice matters
There is something worth thinking about while speech is still available: preserving some of your voice for later. There are two ways to do it, and they are often confused.
- Voice banking
- uses recordings of your speech to create a synthetic voice that can speak new text. Depending on the service, you may make recordings specifically for voice banking, or it may sometimes be possible to use recordings that already exist.
- Message banking
- keeps actual recordings of particular words, phrases, expressions or sounds in your own voice, so they can be played back later exactly as you recorded them — a family member’s name, a favourite expression, a joke, or something you say every day.
Some people do one. Some do both. Some prefer a standard synthetic voice.
Voice and message banking are not communication methods by themselves.
You still need a way to choose or write what you want to say. They are ways of preserving something of your voice that can later be used alongside communication.
If this matters to you, it is worth looking into early rather than assuming you have to wait until speech has changed significantly.
If writing, typing or touching becomes difficult
Difficulty using your hands does not mean you can no longer use a communication device.
You may still have one movement that is easy and reliable: a finger movement, for example, or another movement that can activate a switch.
A switch does one simple thing: it sends a signal when you activate it.
With scanning, the communication system moves through the available choices for you. When it reaches the choice you want, you activate the switch.
One reliable movement can therefore be enough to choose words, spell, use numbers and control a much larger communication board.
You do not need specialist equipment just to see how scanning works. A keyboard key can act as a switch, so it is possible to try the idea before buying anything.
What can be used as a switch?
Examples that may work with Kalam. Compatibility varies between devices, so it’s worth testing before relying on one.
If switch access becomes an important way of communicating, the movement you use and the position of the switch matter. The best setup is individual, and a speech/AAC or assistive-technology specialist can help find something comfortable and reliable.
If another way of selecting is needed
A switch is not the only alternative to touching a screen.
Eye gaze and head tracking
Eye-gaze systems let someone select letters, words or messages using their eyes. The device can then speak what they select. Head tracking uses controlled head movement instead.
Whether either works well depends on the person’s movement, vision, positioning, fatigue and other individual factors. Specialist assessment and setup can therefore be useful.
Some people also use more than one access method and change between them depending on the situation.
Communicating with another person’s help
Technology is not always necessary.
If the person has a reliable way to signal yes, another person can work through the choices for them.
For example, instead of asking someone to point to a letter board, the communication partner goes through the rows. The person signals when the correct row is reached. The partner then goes through the letters in that row until the person selects one. Then they repeat.
The same method can work with common needs or phrases, and may be much faster than spelling every word.
What matters is having a signal the person can produce reliably and the other person can recognise.
The printable boards are laid out for this method.
If you’re helping someone communicate
Use the easiest method the person has available. If they can tell you clearly, let them tell you. If they can write something quickly, there is no reason to make them work through a communication board.
Communication methods should reduce effort, not add to it.
Context and guessing can sometimes help. Someone familiar may recognise a sound, facial expression or attempt at a word immediately.
But do not keep guessing indefinitely. If several guesses have failed, change method.
When using yes/no questions:
- ask one clear thing at a time;
- give the person enough time to answer;
- make sure you both know what yes and no look like.
A yes or no signal might be a blink, an eye movement, a facial movement, a sound or another movement.
If you understood most of what was said, repeat the part you understood rather than making the person start again.
And when the possibilities become too broad to guess, move to writing, a communication board or spelling.
Keep a simple backup
The method someone normally uses will not always be available.
A device may be charging. A switch may be badly positioned. Someone helping for the first time may not know the usual signals.
Having one or two simple backups can make a big difference.
Agree on yes and no
A clear yes/no signal is one of the simplest things to establish. It needs no equipment, and it stays useful even when another communication method is available.
Make sure the people who help know what the person’s yes and no look like.
Keep a printed board nearby
A printed board is deliberately simple. That is also why it is not always the best way to communicate.
If someone can speak comfortably, speaking is easier. If they can write quickly, writing will usually be faster. If their usual communication device is working well, they may prefer to use that.
A printed board becomes particularly useful when the usual method is difficult, unavailable or too tiring. It needs no battery, internet connection or account.
Someone who can point can select directly from it. Someone who cannot point can still use it with another person working through the choices.
Getting someone’s attention is different
Getting someone’s attention is not the same as saying something. A call button can bring someone into the room. You still need a way to tell them what you need.
Call buttons, writing tablets and similar items are gathered in one place.
For urgent situations, have a separate way of getting help. A communication board should not be treated as an emergency alert system.
When specialist help can be useful
Sometimes the next communication method is obvious. Sometimes it is not.
A speech-language/AAC or assistive-technology specialist can help work out what fits the person’s speech, movement and everyday needs.
They can help with things such as:
- communication apps and dedicated devices;
- switch choice and positioning;
- eye-gaze and head-tracking systems;
- mounting and positioning equipment;
- voice and message banking;
- adapting communication as things change.
You do not have to wait until communication has become very difficult to ask.
What is available, who provides it and how it is funded varies by country. An ALS/MND organisation, ALS clinic or local disability service can help you find out what exists where you live.
Where Kalam fits
Kalam is a free communication board for people who can use touch, a keyboard or a single switch. It includes common words and phrases, spelling and numbers, and the tiles can be personalised.
Someone may use Kalam by touch while that is easy, and later use the same board with switch scanning if direct touch becomes difficult.
It opens in a browser, needs no account, and works offline after it has been opened once while connected to the internet.
Kalam uses a voice available on the device. It does not currently use a banked personal voice.
Kalam also does not support eye gaze. If eye gaze is the right way to communicate, use a system designed for it.
A simple place to start
You do not need to prepare every possible communication method at once.
A few things are worth doing early:
There is no reason to replace speech, writing or another method while it is working well.
Make sure the people who help know what it looks like.
A printed board does not depend on a battery, a device or an internet connection.
Print a backup boardThat might mean learning about switch access, voice banking, eye gaze or another communication method.
You do not need to predict exactly how communication will change.
You just do not want the first time you hear about the next option to be the day you suddenly need it.
