Extension Usage Instructions

IMPORTANT: This extension is only for Chromebook devices running Chrome OS.

The extension is free, so you can try all of our voices in an online mode, but then you must buy voices to integrate them to your Chromebook system. Then you will be able to use them with any TTS-compatible application (like ChromeVox).

******** High Quality voices by Acapela Group ********

Add up to 100 voices in 30 languages to your Chromebook.

Voice capability is reinventing the way we all engage with devices and Acapela voices are helping to broaden the native voice offering on Chromebooks with another 30 languages and over 100 voices. The Acapela portfolio for Chromebooks includes authentic children voices as well as adult ones so that students can choose according to their age group and preferences, to feel fully comfortable with the voice they learn with.

Text-to-speech specifically helps individuals that read slowly or with difficulty, people who want feedback when writing or help with spotting errors when proof-reading, those who suffer visual stress when reading text on paper or on a screen or want to simultaneously see and hear. Immediate audio feedback improves word recognition, increases the ability to pay attention and remember information and helps students to recognize and fix errors in their own writing. The wide range of languages covered opens up language learning opportunities.

List of available languages: Arabic, Catalan, Czech, Danish, Dutch(Belgium), Dutch(NL), English(Australia), English(India), English(Scotland), English(UK), English(US), Faroese, Finnish, French, French(Canada), German, Greek, Italian, Norwegian, Polish, Portuguese, Portuguese (Brazil), Russian, Spanish, Spanish (North America), Swedish, Swedish(Gothenburg), Swedish(Scania), Swedish (Finland), Turkish.
