Captions for your videos in different platforms

Captions made with Spoken ONLINE save time for social media creators without compromising the accuracy and clarity of the video.  Captions also make the videos more clear and memorable for the viewer compared to videos without captions.

Automatic captions are generated using artificial intelligence, and the accuracy has currently reached the level of 90 %.

Captions made with Spoken ONLINE are always downloadable, editable and handled with high security and confidentiality in our system.

Captions also make the videos more accessible to people with hearing disabilities, which is why the EU launched the Web Accessibility Directive in 2020.

Captions according to the EU’s Web Accessibility Directive

Starting in the autumn of 2020 in EU, all public organisations must provide captions for video and audio content published on their website according to the Web Accessibility Directive (Directive 2016/2102). If the content of the video and/or audio is otherwise available on the website (e.g. in text format), there is no need for captions.

Applying the Web Accessibility Directive in practice is based on the WCAG 2.1., i.e. the Web Content Accessibility Guidelines. The guidelines are commonly used as a basis for the accessibility requirement legislation in EU many countries.

According to the directive, all meaningful spoken content of the video or recording must be available in written form. The video must include captions in the same language as the video is spoken. Therefore, videos in English must have captions available in English.

Accessible videos with Spoken ONLINE

With Spoken ONLINE you can automatically generate captions of the speech in the video with correct timings. Accessible captions require also other information, e.g. speaker identification, but currently this information is not added automatically.

To make your video accessible, i.e. to fill EU’s Web Accessiblity Directive’s requirements, you can open the ready made .srt caption file for example in Windows Notepad and add the following information:

  • Who is speaking (e.g. [John:])
  • Other essential sounds, such as background music and other soundscape in the background (e.g. [the police siren sounds] or [a knock on the door])

About us

Spoken ONLINE was built in 2017 by an enthusiastic and result-oriented team situated in Helsinki, Finland. The foundation of Spoken ONLINE lays in traditional transcription and subtitling business, where audio files are manually typed into text and video files captioned or subtitled. As speech-to-text technologies develop at a rapid pace, we decided to evolve along with it to create a better world for our clients.

Our automatic caption generator is available in English as well as in 20+ additional languages including a variety of accents.
