Vocalyx allows its user to communicate via the synthesized voice (called speech synthesis) of your device. This voice can express messages prepared in advance or composed by the person themselves.

For this, you have access in Vocalyx to several Communication keyboards. These keyboards are composed of touches, associated with the messages that the synthetic voice will pronounce!

Here is an example :

VOCALYX makes it possible to respond to very different and complementary contexts of conversation and re-education: they range from the most common and anticipated (libraries of pre-recorded and personal images for frequent use), to at least expected (the user writes on the keyboard the sentence he wishes to vocalize). Our tool and our image databases, the Vocalythèques, also allow us to offer you about twenty communication keyboards according to your preferences for children and adults.

All these features will make it easy for you to create your most suitable tool for vocalizeyour words, messages, and phrases at high speed!

Through the photos of the Vocalythèque

centains of photos, sorted by categories or not, allow to compose very quickly sentences and exercises, simply by aligning them.

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

Through the pictograms of the Vocalythèque

Hundreds of pictograms allow to illustrate words, verbs or emotions that would be more difficult to represent in photo. Some users will find themselves in these more refined and precise images, classified by themes or not.

Via 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 to the context of autism because the drawings are devoid of superfluous details that could distract the child from the concept to be communicated.

These keyboards, called "Elementaries", contain sentences from the context of the life of a child, all ready or to be composed according to the level.

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

Via sentences from everyday life

For repetitive conversations, in preparation for future exchanges or for a collection of exercises, you can create your own prepared texts, gathered or not by themes. To express yourself quickly and in complete autonomy at the doctor's, at the bakery, at work, at school, with friends, or to train at home, it's up to you to set the tone!

The most : Participate and be reactive in your questions and answers in the conversations with your entourage thanks to the various themes that we propose you and your own personalized keys !
