Speech synthesis for devices, accessibility and brand voices
Acapela Group is a Belgian speech technology company that has been building text-to-speech engines for specialised hardware long before the current wave of hosted voice APIs. Its catalogue covers dozens of languages and hundreds of voices, including genuine children's voices, expressive personas, and a voice banking service that lets someone losing their speech preserve their own voice from recorded sentences. Much of the business is licensing rather than self-service: an SDK for desktop and mobile platforms, an on-device engine for assistive devices and vehicles, and royalties per unit. This is not an API you sign up for overnight.

It is the practice of recording a set of sentences while you can still speak, so a synthetic version of your own voice can be built for later use. Acapela's service targets people whose condition will take their speech.
Not in the way a consumer API works. Most deployments are licensed projects with a developer kit and a per-unit royalty, which suits devices and long-lived products rather than one-off videos.
Several dozen, with regional English variants among others, plus specialised children's voices. The exact list changes over time, and some voices are licensed only for particular device categories.
