An innovative yet simple and all-in-one product for seamless access to written information, no matter where the user is, at home, in the office or on the move using different computers.

Announcing a major update and adapting the lifecycle of Infovox4.

The all-in-one local and portable talking companion for visually impaired users has been updated (now version 2021.04.19).

For years now, Infovox4 enabled visually impaired users to seamlessly access written information, speech empowering any PC with Acapela’s digital voices, for real time vocalization of written content.

New Version, automatic update

The new version brings major updates to Arabic, Finnish, German, Norwegian, Brazilian, Polish, Russian and Swedish languages. The update will be automatic through the ‘live update’ feature and users will benefit from the latest improvements made to Acapela’s speech synthesis and will be able to access the latest version of the embedded NVDA screen reader.

Announcing the end of support beginning July 2022
For 20+ years, Infovox was selected by thousands of users worldwide to bring greater ease to their daily lives. Throughout those years, we have worked continuously to adapt Infovox. Based on the technology evolution, Accessibility industry changes and Windows OS policy updates, which impacted our sales in this field this last years, Acapela made a difficult decision and has decided to end the support of Infovox4 and to focus on new products. The product will remain fully operational and available as long as Windows OS allows it.

We would like to thank all the Infovox users for their confidence and precious feedback over the years. We also address our gratitude to our faithful network of distributors worldwide, who definitely contributed to making the Infovox solution a bespoke product for so many users.

In order to ensure the stability of this latest update, to give all possible support to the community and to prevent and tackle any kind of possible support needed, we will maintain the active life and support of Infovox 4 up to July 2022. Beyond that date, users will be able to continue to use the product they acquired on their current computers, but please note that we will not make any further updates to support upcoming new versions of Windows OS.
Accessibility remains a major focus at Acapela and our involvement towards the visually impaired users remains unchanged. Acapela TTS Voices for NVDA may be an interesting alternative to use high-quality and high performing voices to your screen reader. Click here for more information.

We are actively working on VoiceAI and neural TTS, opening new opportunities to all user profiles through our cloud solution, standalone products and a wide range of software development kits.
