Acapela TTS Engine Extension

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.

******** Instructions ********

1/ Please check that you have a valid internet connection, as the app needs to contact our server to get the voice list.
2/ Open the extension options page.
3/ Browse the list of voices retrieved from our server.
4/ You can test any voice online. You can type your own text in the \"Type some text here to try\" area.
5/ The ‘Buy’ icon will open an in-app billing window, asking for confirmation of your purchase.
6/ After purchase, the voice will appear with a download icon. Click on it to start the installation. This requires an internet connection and may take some time. Beware that voice data are very big (100-200MB) so a strong and stable internet connection is recommended.
7/ After a successful installation, select the Acapela voice in your TTS-compatible application.

Michelle Putnam (ID: 000000dbb62e6c66) Voted 1 ★ - Updated 11/15/2023 I’m disabled, and need help to read. I'll just cut to the chase, I'll be reviewing facts not opinions. FYI, I can only understand English. Is it actually free: No, and neither are the voices. Does it work?: The interface is only compatible with ONLY Chromebooks, Even when it marketed itself as being able to work on my computer. Is it as Advertised: Not in the slightest. Voices are to be paid for, and will not be provided. Why the stars? Even if I didn't have a Chromebook, the information provided is misleading. Having the extension be “free” in the voices be paid for is a scam. So advertising Functions that are not available In the product for download is misleading. (How to fix) My recommendation: Starting with the obvious, clearly labeled application as only designed for Chromebooks, then clearly states that the consumer needs to purchase voices.
