Acapela Group

Acapela sits in an unusual position in the synthetic voice market. Commercially it builds custom brand voices and supplies embedded speech to device manufacturers. Socially, its my-own-voice programme lets people with degenerative conditions such as ALS bank their voice while they still can, so that a communication device can later speak in something recognisably theirs.

The company is based in Mons, Belgium, and is now part of Tobii Dynavox, the Swedish assistive technology group — so the ownership as well as the operation stays European.

Voice Banking and Assistive Use

my-own-voice takes a set of recordings from someone who still has speech and produces a synthetic version they can use after they lose it. For families facing a diagnosis of ALS or a laryngectomy, the difference between a generic device voice and one built from the person's own recordings is not a technical detail.

This work also explains Acapela's engineering priorities: intelligibility at speed, reliable pronunciation and offline operation matter more in assistive contexts than dramatic expressiveness.

Embedded and Offline Deployment

The embedded SDK runs entirely on-device, with no network dependency. Communication aids, in-car systems, public transport announcements and industrial equipment all need speech that works when connectivity does not, and that requirement rules out most of the current generation of cloud-only AI voice services.

For data protection, on-device synthesis means no text is transmitted anywhere — the cleanest possible position for medical or personal communication.

Character and Child Voices

Acapela maintains an unusually varied voice catalogue, including child voices and stylised character voices that are hard to source elsewhere with proper commercial licensing. For educational products, games and children's media, that catalogue is a practical differentiator.

Limitations to Consider

Acapela's voices are built for clarity and reliability rather than for the emotional range of the newest generative models, so for cinematic or highly expressive work Respeecher or a generative provider will produce better results. Pricing for embedded and enterprise use is quoted rather than published, and the self-serve options are aimed at consumer apps rather than professional production.

Who Should Use Acapela Group

Assistive technology providers, device manufacturers, educational publishers and organisations that need a distinctive owned brand voice with proper licensing. It is also the first place to look for anyone considering voice banking ahead of losing their speech.
