Embed 608 Captions and Audio Translations into an SRT Stream

Insert real-time captions and optional audio translations into a live SRT stream using a SyncWords Service in a few easy steps.

Step 1 - Create a Service

In SyncWords, create a new service or navigate to your existing service configuration.

Please see Step 1: General Settings - How do I create a Service using the new UI? for more information.

 

Step 2 - Provide Input Media

During the Step 2: Input Media, you can select the type of stream that is used as the source for speech recognition and the video stream output.

From the Input Media section,  select SRT. Then select the "SRT Push (listener)" or "SRT Pull (caller)" option.

Please see Step 2: Input Media (SRT) - How do I use SRT as an Input source for my Service using the new UI? for more information.

NOTE: The SRT Pull URL must be publicly available or SyncWords will not be able to ingest it.

Step 3 - Set up Transcription

Now that we have set up the incoming stream we need to set up the Transcript section to create the captions.

Configure the transcription settings to create captions from your live stream audio.

Please see Step 3: Transcription - How do I enable Transcription for my Service using the new UI? for more information.

NOTE: 608 captions will always be delivered to Channel 1

Step 4 - Set up Audio Translations

To add real time AI audio translations as alternate audio tracks to your SRT stream go down to the Translations section. In this section, you can add real-time AI text translations and audio dubbing to your live stream.

Please see Step 4: Translation - How do I enable Translation for my Service using the new UI? for more information.

Read our article on How to Setup Audio Translations for more details. 

Step 5 - Set up the Output

The last step is to set up the stream that will go back out to the client with embedded 608 captions and audio translations prior to delivery to its final destination.

In your SyncWords Service configuration, navigate to the Output section and select "SRT PUSH (Caller)" or "SRT PULL (Listener)" option.

NOTE: You can also select RTMP from the dropdown. See the Step 5: Output of our RTMP article for set up instructions.


Make sure the "Embedded 608" is enabled under Captions & Subtitles. Make sure to click "Continue" once your selections are set. This moves to the next step where you can preview your Service settings.
