Delta Process is a company specialised in commercial architecture and a pioneer expert in the processing of audio and video streams with secure protocols. The company was founded in 1993 by Hervé Allart de Hees. In 2006, some major companies contacted us for their deaf or hard of hearing employees.

Thanks to this partnership, Delta Process could create a solution dedicated to communication in the workplace between hearing and hard of hearing or deaf people. Tadeo began in 2007 and delivered its first Live Speech Transcription (LST) and French Sign Language Video-Interpretation via its remote platforms. The services rely on a technological base (proprietary software) and expertise (e-transcription and video-interpretation), which meet the quality and security required by employers. From this knowhow, the service Acceo was created for companies and public services. It provides phone and on-site accessibility for hard of hearing and deaf people.
