+Closed captions are a textual representation of a voice or video conversation that is displayed to users in real-time. Azure Communication Services Closed captions offer developers the ability to allow users to select when they wish to toggle captions on or off. These captions are only available during the call/meeting for the user that has selected to enable captions, Azure Communication Services does **not** store these captions anywhere. Here are main scenarios where Closed Captions are useful:
 
-Azure Communication Services allows one to enable Closed Captions for the VoIP calls in private preview.
-Closed Captions is the conversion of a voice or video call audio track into written words that appear in real time. Closed Captions are never saved and are only visible to the user that has enabled it.
-Here are main scenarios where Closed Captions are useful:
+## Common use cases
 
-- **Accessibility**. In the workplace or consumer apps, Closed Captioning for meetings, conference calls, and training videos can make a huge difference. Scenarios when audio can't be heard, either because of a noisy environment, such as an airport, or because of an environment that must be kept quiet, such as a hospital. 
-- **Inclusivity**. Closed Captioning was developed to aid hearing-impaired people, but it could be useful for a language proficiency as well. 
+### Building accessible experiences
+Accessibility – For people with hearing impairments or who are new to the language to participate in calls and meetings. A key feature requirement in the Telemedical industry is to help patients communicate effectively with their health care providers.
+
+### Teams interoperability 
+Use Teams – Organizations using Azure Communication Services and Teams can use Teams closed captions to improve their applications by providing closed captions capabilities to users. Those organizations can keep using Microsoft Teams for all calls and meetings without third party applications providing this capability. Learn more about how you can use captions in [Teams interoperability](../interop/enable-closed-captions.md) scenarios.
+
+### Global inclusivity 
+Provide translation – Use the translation functions provided to provide translated captions for users who may be new to the language or for companies that operate at a global scale and have offices around the world, their teams can have conversations even if some people might not be familiar with the spoken language.

+## Privacy concerns
 
+Closed captions are only available during the call or meeting for the participant that has selected to enable captions, Azure Communication Services doesn't store these captions anywhere. Many countries/regions and states have laws and regulations that apply to storing of data. It is your responsibility to use the closed captions in compliance with the law should you choose to store any of the data generated through closed captions. You must obtain consent from the parties involved in a manner that complies with the laws applicable to each participant. 
+ 
+Interoperability between Azure Communication Services and Microsoft Teams enables your applications and users to participate in Teams calls, meetings, and chats. It is your responsibility to ensure that the users of your application are notified when closed captions are enabled in a Teams call or meeting and being stored.
+ 
+Microsoft indicates to you via the Azure Communication Services API that recording or closed captions has commenced, and you must communicate this fact, in real-time, to your users within your application's user interface. You agree to indemnify Microsoft for all costs and damages incurred due to your failure to comply with this obligation.
