Read below how

this works.

  • Synchronized audio: the spoken text is synchronized with the subtitles.

  • Comply with EU accessibility guidelines: The Audiovisual Media Services Directive (AVMSD - 2018).

  • Pleasant voices and diverse languages: select the desired voice to have the subtitles read aloud.

With AudioSubs you provide reliable and accurate
spoken subtitles to your users.


With Sensotec AudioSubs' AI-driven OCR technology, the subtitles are filtered out of the broadcast video in real time.


This information is then converted to speech with high accuracy and synchronized with the displaying of the subtitles.

This technology applies to a variety of languages and characters.

Our extensive database detects all characters and then converts them to spoken text.


As a result, we achieve an extremely high accuracy while the spoken text is clearly understandable by the listener.

As a result, they barely understand what is being said, are less engaged and stop watching television. This creates a sense of exclusion.


For them, the subtitles are not sufficiently distinguishable from the background and disappear too quickly to follow.


For visually challenged and blind people, spoken subtitles are the solution.


With Sensotec AudioSubs, Sensotec offers the technology to convert subtitles to spoken subtitles in real time.


Watching TV is a favorite pastime for many people. Watching a program, series or movie is part of a relaxing evening. Yet this is not feasible for everyone.


People with a visual challenge are confronted with subtitles they cannot read.

The result

Thanks to Sensotec AudioSubs technology, following a foreign-language program, series or movie becomes accessible again for visually challenged and blind people.


They can follow confortably thanks to the spoken subtitles. This is how Sensotec AudioSubs makes watching TV accessible again.

Please note: Sensotec AudioSubs concerns spoken TV subtitles, not an audio descriptive narration of what is happening in the scene (audio description).

Who are we doing it for?

As the use of subtitles has expanded, consequently the applications of spoken subtitles are also expanding.

  • For the visually challenged and blind

  • For people with dyslexia

  • In case of double screen use where, for example, TV and smartphone are used at the same time

  • For better understanding of dialogue in live broadcasts or dialects
