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 :

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 wheter for repetitive conversations, in preparation for future exchanges, or for a collection of exercises. These pre-made sentences can be organized into subcategories of 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, thanks to the various themes that we offer along with your own customized keys !

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

You can choose for a key to become a " family key " in order to group your messages into categories, or automatically set an full screen (when you click on the key, the image appears full screen). This is useful for being able to point your finger at specific element in the image.

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 :

  • Replace page to page dragging by clicking on an arrow
  • Replacing a quick and simple press with a long press for people with finger shaking

Adjusting the synthetic voice

The synthetic voice reads the messages, written in text, associated with the keys selected by the user (by image or text keys) : 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 keyboards

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