Captions & Transcripts

Add human-generated captioning to a live event

The Webcast platform offers options for human-generated or computer-generated captions on an event. Human-generated captions allow for support in multiple language and have an increased accuracy compared to computer-generated captions but require additional steps in the booking and setup process. The computer-generated caption setup is seamlessly integrated directly into the Webcast platform but offers English only captions. Note that computer-generated captions have an increased possibility of transcription errors compared to human-generated captions.

To include human-generated captions, you must request captioning services, set up a Custom Tab with the StreamText embed code, and then invite the captioner as an attendee. On the day of the event, the captioner joins as an attendee and types the captions into StreamText, which are then displayed to the audience in the Custom Tab.

Request captioning services

We can book live captioning for your event.

To request live captioning:

You can also use your own third-party captioning provider, as long as they use the StreamText platform.

When you request live captioning through us, we provide your event ID to the captioning provider, who uses it to identify your event in their StreamText account. When you set up the custom tab, include this event ID in the embed code. If you schedule your own captioner, we recommend that you give them your event ID to use as their StreamText event name (identifier); confirm the value they used and include it in the embed code. To learn more about the process for scheduling captioning services, contact Support.

Example code

Use the following example code to embed captions in the custom tab. In the code, find event=1234567 in the code and replace 1234567 with the event ID for your event. If you're using your own captioning services, replace 1234567 with the event name provided by the captioner.

Important: If you requested captions in a language other than English, you must include an additional language parameter to the link for them to display correctly. For example, if you requested captions in Spanish, you must add &language=es to the link after the event ID or name. For more information, see StreamText URL formatting.

Always preview the tab setup before the Live event.

To test captioning for your event:

  1. In the Webcast Admin portal, edit the event.
  2. On the Event Content tab, edit the sidebar tab you created for captioning and replace your event ID or name with ihaveadream.

    ...src="https://www.streamtext.net/text.aspx?event= ihaveadream &chat=false...

  3. Click Save Changes to save the coding. Then click Save and Continue to save changes to the event content.
  4. Now preview the web player: click the Event Summary tab and at the top of the page, click View My Event .

Make any changes to the display. When ready, go back and place your event ID in the sidebar tab coding.

StreamText URL formatting

The captions can be visually controlled by passing various query strings (parameters) in the URL. Here are the options used in our example code; we hide various elements to ensure captions display well in a sidebar tab. For a complete list of options, see this StreamText help article.

Query String Purpose Used in our example code Result
language

Required for displaying captions other than English. The ISO 639-1 code for the caption language.

Examples:
Chinese (Simplified) - &language=zh
French - &language=fr
German - &language=de
Spanish - &language=es
For a complete list of language codes, see this Google article.

Add human-generated captions to a recorded event

To add captions to a replay or to an On-Demand or Simulated Live event, you need a timed caption file in VTT (WebVTT) format. A timed caption file contains the text of what is said in the recording, plus time codes for when each line of text should be displayed. You can request a caption file for your event or ask your captioning provider for a compatible file.

Notes:

Once you receive the caption file, upload the file in the setup of your event. You can offer captions for your event in different languages; just upload a separate timed caption file for each language you want to provide. Captions are shown inline with the video. You can display them automatically or allow attendees to turn them on as needed. Attendees can turn captions off at any time.

Important: Captions are timed with the event audio. If you edit an event recording after receiving a caption file, the captions will be out of sync. You must request a new caption file.

About computer-generated transcripts

Automated transcripts are available for any type of event - Live, On-Demand, and Simulated Live. Automated transcripts are great for capturing the event audio in a file for your own use and for providing synced captions with a searchable transcript for people watching the event recording. You can also allow attendees to download the transcript.

The system uses the event audio to generate the transcript, including primary media clips and overlay videos. Generated transcripts are available within 24 hours of a Live event ending or a recorded event being published.

Note: Automatic transcription and key phrases might not be available on your account. To request these features, contact Support or your sales representative.

To generate an automated transcript for an event, go to the Event Content tab and open the Add Automated Transcript section.

Edit the recording and update the transcript

After the event has been published or archived, review the recording and make any edits to the event content. Publish your changes to update the event audio and transcript timings. The system processes the event recording, generates a new version of the transcript, and republishes the event. This is an automated process, so you can edit the event and republish the recording as many times as you need.

Review the transcript

The transcript is computer-generated, so review the transcript for accuracy. To edit it, open the event in the editing studio and click Transcript. When finished, click Save Draft before you close the Edit Transcript window and then republish the event.

Examples

Viewers can open the full transcript in a separate panel and search it.

You can also show the generated transcript as scrolling captions under the video player.

Edit a computer-generated transcript

For automated transcripts. You can open a generated transcript in the editing studio and review and edit it. The transcript includes time codes that allow you to play the audio from the beginning of the phrase, so you can compare each transcribed phrase to what was actually said. You can also use the search bar to search for words or phrases in the transcription that you know need to be corrected.

The system uses colors to highlight words that need to be reviewed for accuracy.

Transcript example

After you save your changes and publish the event, the transcript is generated again with your updates. When ready, you can download the new version. If you made the transcript available to the audience, the transcript is also updated in the event recording.

To edit the transcript:

  1. Sign in to the Webcast Admin portal and edit the event.
  2. On the Event Summary tab, click Launch On-Demand Studio or Launch SimLive Studio.
  3. In the editing studio, under the video player, click Transcript.

Add live interpretation with Interprefy

Extend your event’s global reach by pairing your webcast with Interprefy's interpretation widget. Interprefy allows multi-language support by providing viewers with real-time interpretation in multiple languages. The audio interpretation widget can be added to Live audio-only or video webcasts.

Note: Webcasts support audio interpretation services only. Video interpretation services are not supported.

Schedule your Interprefy event

Before your event, you must reach out to Interprefy directly to schedule an interpreter and receive an Interprefy widget link.

Your Interprefy widget link should look like this: https://interpret.world/login=widgetdemo

For managed events, you must provide the event production manager with the Interprefy widget link at least 72 hours before the event start time.

Example code

Use the following sample code to embed the Interprefy widget. Replace https://interpret.world/login=widgetdemo with your Interprefy widget link.
