 ### Whats new
 - [Azure Bot Service](./README.md#ABS-whats-new)
-    - Direct Line Speech Channel – (new) Almost every enterprise bot customer is looking at least one or more scenario involving voice enabled assistants, whether it be customer care or virtual assistant, often via IoT.  Quality of experience, minimal latency, and custom wake words are all critical to a great experience. We are bringing together the Bot Framework and Microsoft's Speech Services to provide a channel that enables streamed speech and text bi-directionally from the client to the bot application. This also brings together our development communities for Virtual Assistants and Mixed Reality around our common developer offering. To sign up, add the 'Direct Line Speech' channel to your Azure Bot Service.

 - [Bot Framework SDK](./README.md#V4-whats-new)
     - [Adaptive Dialog][47] | [docs][48] | [C# samples][49] :: Adaptive Dialogs enable developers to build conversations that can be dynamically changed as the conversation progresses.  Traditionally developers have mapped out the entire flow of a conversation up front, which limits the flexibility of the conversation.  Adaptive dialogs allow them to be more flexible, to respond to changes in context and insert new steps or entire sub-dialogs into the conversation as it progresses. Additionally as with other SDK V4 concepts, we have defined adaptive dialogs such that they can be defined via [metadata files][50] that are interpreted at runtime; which allows us to have tooling on top of this and integrate with services.
