-## Speech SDK and Speech Devices SDK
-
-To simplify the development of speech-enabled applications, Microsoft provides the [Speech SDK](speech-sdk.md) for use with the new Speech service. The Speech SDK provides consistent native Speech to Text and Speech Translation APIs for C#, C++, and Java. If you're developing with one of these languages, the Speech SDK makes development easier by handling the network details for you.
-
-Microsoft also offers a [Speech Devices SDK](speech-devices-sdk.md), an integrated hardware and software platform for developers of speech-enabled devices. Our hardware partner provides reference designs and development units, while we provide a device-optimized SDK that takes full advantage of the hardware's capabilities.

-If you're using a supported programming language, the [Speech SDK](speech-sdk.md) makes development easier. The Speech service also has a [REST API](rest-apis.md) works with any programming language, but does not offer all the functions offered by the SDK.

-The Speech service also provides WebSockets protocols for streaming Speech to Text and Speech Translation. The Speech SDKs use these protocols. We encourage you to use the Speech SDK rather than trying to implement your own WebSockets communication with the Speech service. However, if you already have code that uses Bing Speech or Translator Speech via WebSockets, it is straightforward to update it to use the Speech service. The WebSockets protocols are compatible; only the endpoints are different.
