About us

Voice User Interfaces to bridge the Digital Divide: voicebridge, a Hishab Ltd. subsidiary, is a Saarbrücken-based software company developing voice based applications and middleware for rural populations in developing countries that lack internet access. Our product enables speech access to web based services via phone.

Developing Interfaces of the Future

We are researching and applying machine learning tools and methodologies to create tailor-made, unique voice interfaces for developing countries and underrepresented languages & dialects. Voice is becoming the interface of the new generation in industrial countries, controlling automated homes and self driving cars. We aim to take this technology to places where the difference it can make is not merely one of convenience, but of participation.

Social Impact

Billions of people all around the world do not have access to information technology, including, and most importantly, the internet – a situation which constitutes a major inhibitor to social, educational and financial inclusion. This disconnect most strongly affects poor rural populations in developing countries. We are working on solutions that bridge this digital divide: Our technology enables these communities to access internet-based applications via voice input using conventional phones.
