Authentic children voices by Acapela Group

Children’s voices created by Acapela Group: made by and for children!

The cheerful family of Acapela genuine children’s voices give the say to young users around the world – Australian, UK & US English, bilingual US English/North American Spanish, French, German, Italian, Norwegian and Swedish are already available.

Acapela Group is the only voice specialist worldwide to offer users such a rich repertoire of children’s voices which are truly lifelike. Read the full story.

All Acapela children’s voices are recorded by and for children.

We are very proud of our children’s voices that enable kids around the world that have difficulties to communicate, speak or learn to finally express their thoughts, needs and desire with a voice they like and that may change their daily lives.

AAC solutions combined with tablets have revolutionized the industry, allowing the development of innovative approaches to help people with specific needs achieve greater autonomy. The voice synthesis developed by Acapela gives users the means to better interact with the people around them.

Acapela’s children voices voice empower tablets, smartphones, smart toys to facilitate communication, interactivity and engagement.

Challenge background

Since decades, Augmentative and Alternative Communication (AAC) solutions give a voice to children who cannot speak. Until recently, children with communication difficulties only had access to adult text to speech voices to express their thoughts, needs and desires.

Because a children communicating with an AAC device deserves the right to speak with voices that reflect their age, together with AssistiveWare, the leader in AAC applications for iOS we take up the challenge to develop genuine text to speech children’s voices, for the first time ever.

World premiere

And in 2012, we proudly unveil the world’s first genuine, natural-sounding children’s voice, in British English, providing a voice to over 74,000 children and teens in England who cannot speak for themselves.

These new voices will make such a difference to them and to their families – in particular, in terms of enabling them to be included, to have normal relationships with their peers and enjoy everything that so many other children take for granted,” said Anna Reeves, England’s National AAC coordinator.

The challenge was to find, coach and record kids, to get the essence of their original tone and capture all the specific vocal characteristics of a young voice. No artifices or effects, with, as a result, a fresh, authentic and naturally young tone that kids will adopt without hesitating.


Identifying the right voice talents and reviewing voice samples took a number of months.

Then, the demanding steps usually used for the creation of an adult professional voice have been adapted to the child’s habits and behaviour.

When recording an adult, recordings have to be homogeneous throughout the sessions, from one day to the next. It is clearly impossible to ask the same of children. Our R&D team had to rethink and adapt the process for young speakers. The development of the children’s voices has required tremendous dedication and specialized work from our experts.

Specific recordings of children’s typical exclamations and sounds have also be done to create an even more natural spontaneous audio result.

Once the recordings done, the raw material needs to be processed and then repeatedly tested to make sure words are pronounced correctly and sound natural.

Creating the first two voices took more than 2,500 hours of research, recording, processing and development. To learn more about this process, watch the short video, “Text to speech, how does it work?”.

This ground breaking project is a fulfilling result and a reflection of our long time leadership in this field. We will continue to add new children’s voices to our portfolio and so help change the way kids with disabilities can benefit from voice technologies. Our children’s voices are used daily by thousands of children throughout the world and that is the best proof that we are on the right track.
