How to use StreamText with Microsoft Teams

Now you can deliver captions directly into Microsoft teams. You will  use  the  realtime ingestion option  to  connect.

First you will need to enable CART on teams. Here  are the instructions https://support.microsoft.com/en-us/office/use-cart-captions-in-a-microsoft-teams-meeting-human-generated-captions-2dd889e8-32a8-4582-98b8-6c96cf14eb47

1. Normal setup for your  StreamText event except for setting the Realtime Ingestion settings  on the CART/Captioning tab when  you schedule the event.
2. MS Teams CC token -  You will need to have the meeting host provide you will the MS teams CC token. Here is an example of what that will look like: (Please do not use it will not work just an example)

3. Realtime Ingestion section on the CART/Captioning Tab. You can also access this on a live event using the Event Control -> Change Settings.  Below are the recommended settings for that section. ( see step 5 below for adjustments to these settings)
   
   1. Caption URL - The copied MS Teams CC token
   2. Correction Buffer - MS Teams does not support updates so the captions need to be complete before they are sent out similar to Zoom.  We  recomend 3 seconds  however your caption software may have a delay feature so you may be able to adjust this down.
   3. Check Send Complete lines
   4. LIne Length - Set to 50

4. Once the event is live or you update the setting on the Event Control the event will publish to the MS Teams Room. Note you need to have at least one participant watching CC for the feature to be enabled. 
5. How to reduce the delay 
   You may notice a 3-5  second delay with the initial settings  above. There are adjustments you can make to reduce this if needed. The reason for the settings are to format the text for the line at a time captions in MS Teams. It does not support word for word streaming, The display is a rollup display so each line will push the next line up. MS Teams has a two line display.
   1. Reduce the correction buffer duration: Your captioning software may already buffer the output so that translations are completed before the  text is sent to StreamText. If so you can reduce this to zero in some cases. However if you are on Dragon or Case  Catalyst for example you will need some buffering to prevent retransmission of the same text. Reduce it until you start to see duplication in the output. If you do see  duplication in Teams then you will need to increase it so translations can complete correctly. 
   2. Reduce the line  length: 50 charters is a recommendation based on  normal  pace of conversation however this  also will add delay. The shorter the line length the faster the  captions will be sent to Teams. We do recommend not  going  below 32 charters on this setting to keep the captions from scrolling up too fast.
