Express Discover Adjust Personalize

Vocalyx allows its user to communicate via the synthesized voice (called speech synthesis) of a smartphone or tablet device. This voice can express messages prepared in advance or composed in real time by the user.

For this purpose, Vocalyx has several Communication keyboards. These keyboards are composed of on-screen buttons, associated with messages that the synthetic voice will say out loud!

Here is an example:

Here is an example:
  • You will find your way to communicate through a wide array of options: DISCOVER >
  • You will be able to adapt your communication tool according to the specific needs of the user: ADJUST >

VOCALYX makes it possible to respond to both different and complementary contexts of conversation and re-education: they range from the most common and anticipated (via libraries of pre-recorded and personal images for frequent use), to the least expected (where the user writes on the keyboard the sentence he wishes to vocalize). Our tools and our image databases, called the Vocalibrary, also allow us to offer about twenty differing communication keyboards catering to specific categories and preferences for children and adults.

These features make it easy for you to create the most suitable tool for vocalizing your words, messages, and phrases at high speed!

The photos of the Vocalibrary

The photos of the Vocalibrary

Hundreds of photos, sorted by categories or not, allow the quick composition of sentences and exercises, by simply aligning them in the order you would like them to be spoken.

The photo format makes communication accessible to people who have reading comprehension disorders, without infantilizing them.

The pictograms of the Vocalibrary

Hundreds of pictograms allow the illustration of words, verbs or emotions that would otherwise be more difficult to represent in photo. Some users will find themselves using these more refined and precise images, which can either be classified into themes or not.

Keyboards of different levels for <strong>children</strong>

Keyboards of different levels for children

We have designed 4 communication keyboards for children with the ARASAAC image database, used by some orthophonists.

These pictograms are particularly well suited within the context of autism because the drawings are devoid of superfluous details that could distract the child from the concept to be communicated.

These "Elementary" keyboards contain sentences from the context of the life of a child, and are available pre-made or they can be composed according to the child's level.

The best part: 1 click on a picto = 1 message to his entourage

Sentences for everyday life

You can create your own pre-prepared texts whether for repetitive conversations, in preparation for future exchanges, or for a collection of exercises. These pre-made sentences can be organized into subcategories or left altogether. To express yourself quickly and in complete autonomy at the doctor's office, at the supermarket, at work, at school, with friends, or for practising at home, Vocalyx can be used literally anywhere!

The best part: Participating and reacting to questions and answers in conversations with those around you, all thanks to the various themes that we offer along with your own customized keys!

Communication from a distance

Once your messages are created using either images or text or both, Vocalyx can change them completely into text and send them to anyone by e-mail or a SMS/text message. You can ask someone to run an errand, ask for more information, or simply have a conversation, and you can at any time interact with your relatives, your health professionals, or with artisans near you.

The best part: whatever your agility and capacity, there is no longer anything to prevent you from sending text messages and e-mails!

The Vocalyx community

Customize your communication keyboards

Add your photo keys, pictos or texts


You can add your personal photos (ex, the photo of a relative), or choose from our library of photos and pictograms, called the Vocalibrary.

You can save a home-made voice recording onto a certain key, or choose for it to be read by the synthetic voice.

Aa To simplify the user interface you can modify the text associated with the key and differentiate between the text title that appears at the bottom of the key and the statement that is said out loud (ex, Title bread / Statement: I would like bread).

You can create text keys only, by simply refraining from adding an image.

You can choose for a key to become a " category " in order to group your messages into categories and subcategories, or automatically set the image to full screen mode. This is useful for being able to point your finger at a specific element.

Increase text size

Choose from several text sizes between small and very large by setting the grid size of your keyboard


Changing your grid format, will adjust the size of each key and therefore also the number of keys in each row and column:

Ability to adjust key size meets the needs of:

  • Visual deficits
  • Motor disorders
  • Attention Deficit Disorder

Create your communication keyboard

Our tools allow you not only to customize the communication keyboards already existing in Vocalyx, but also to create your keyboard from scratch: you have all the tools in hand to create the keys adapted to the unique wants and needs of the user (color, photos, pictograms, choice of the most important messages,etc).

You can browse through the 2000 pictograms and 1000 photos available in the Vocalibrary¸ located in your Vocalyx application.

You can create your personalized keyboards or download more provided by Vocalyx and available on our list of public keyboards in the application (ex. a special hospital keyboard).

Choose your favorite keyboards

From all the keyboards mentioned above, you can adjust your home page by selecting your favorite keyboards. By using the star system located in the list of keyboards, you can choose which ones will be directly accessible on the home page.

Customize your message display

In the Vocalyx communication keyboards, the selected messages will appear in the text box or playback window. You can choose how this message will appear:

These options allow you to completely remove the text box in order to display only the image of the selected key, or you can display the message as both image and text, or as text only.

If you check the box "add text manually" it allows you to activate or deactivate the option of clicking inside the text box in order to type using the QWERTY keyboard.

Saving your custom settings

To avoid losing your custom settings, it is recommended to use the backup function of your communication keyboards. This can save a lot of time in case of accidental uninstallation of the application or loss, damage, or theft of your device.

By saving your work, you can:

  • Download custom keyboard(s) to all your devices
  • Find the keyboard(s) in case of loss

Customize your settings

The general settings are available on the home page of the Vocalyx application. They are designed to adjust the overall use of communication keyboards down to the smallest detail.

Modify gestures

<i class='fa fa-eye icon' aria-hidden='true'></i>Customize your message display

You can simplify the gestures on the touch screen, in the "Gestures" section of the settings:

  • Replace page to page swipe mode by clicking on a direction arrow
  • Replace a quick and simple press with a long press for people who shake or tremble

Adjusting the synthetic voice

The synthetic voice reads out loud the messages that are associated with the image or text keys selected by the user. In this way it can represent the voice of the user.

You can set:

  • Its tonality (higher or lower)
  • Its cadence (faster or slower)
  • Its type: woman's, man's, girl's or boy's voice (If your tablet does not have this option we advise you to download the voice that suits you)
<i class='fa fa-eye icon' aria-hidden='true'></i>Customize your message display

Protect custom settings and keyboards

To simplify the use of Vocalyx for your child or any user, you can use a setting that allows only a dedicated access only to the communication keyboards. This would give access to editing and customizing only to a parent or caregiver by the use of a code. This setting is useful to avoid unfortunate mishaps that could compromise your custom settings.
