Enhance your live stream with rolling text and machine translations

14 Feb 2023

In addition to remotely adding closed captions to a live stream, Clevercast also has the ability to display the live audio transcript as rolling text in a separate widget. This allows viewers with a hearing impairment to better understand what is being said in the live stream.

Clevercast also supports automatic translations to an unlimited number of languages. Viewers can select their own language in the widget, and read the translated text while watching the live stream.


Advantages of a rolling text widget

Whereas closed captions are limited to what is being said in the live stream at a given moment, the widget shows the full text which automatically keeps on scrolling vertically. This way, it allows for better readability and allows the viewer to easily follow the dialogue. This can be an added value if there are many long or complex sentences, such as at scientific conferences.

In addition, the widget allows viewers to re-read previous sentences at any time. By highlighting what is currently being said, the widget makes it easy for viewers to get back to the present. When new sentences appear, the widget’s cursor will scroll down automatically.

The choice for a rolling text widget instead of closed captions can be made on a case-by-case basis. There is only a difference in presentation. The ways in which the live stream audio is converted into text remains the same.

You can display the widget on either side of the video player. Its appearance can be customized; you can change both the color of the text and the color of the highlights.


High accuracy of speech-to-text conversion

Clevercast supports several ways to convert the audio of a live stream to text in real time and translate it into multiple languages. This can be done through (a combination of) simultaneous interpretation, real-time transcription and automatic caption generation using AI. By leveraging the latency inherent to the HTTP Live Streaming protocol, Clevercast allows you to vastly improve accuracy and readability of the live transcript.

For the highest degree of accuracy for a single language, we recommend using remote captioning. Clevercast supports stenotype keyboards and re-speaking software to facilitate captioning and improve accuracy. Captioners can take turns for the same language and even correct each other’s text before it appears. This way, Clevercast allows you to generate an error-free rendition of the live stream audio.

The initial transcript, can be automatically translated into any number of languages in real time. If the initial text is accurate, the quality of the translated captions will also be improved.

If desired, we can source interpreters and captioners and help you manage them, to ensure high-quality captions in real time.
