-The SDK allows you to build your own ambient devices with a customized wake word—so the cue that initiates a user interaction is unique to your brand. It uses multi-channel audio to provide more accurate speech recognition via noise suppression, echo cancellation, far-field voice, and beamforming.
+The Speech Devices SDK consumes the [Speech SDK](speech-sdk.md), and uses the Speech SDK to send the audio processed by our advanced audio processing algorithm from the device's microphone array to the [Microsoft Speech Service](overview.md).  It uses multi-channel audio to provide more accurate far-field [speech recognition](speech-to-text.md) via noise suppression, echo cancellation, beamforming and de-reverberation.
 
-The SDK facilitates a variety of voice-enabled scenarios, such as drive-thru ordering systems, in-car or in-home assistants, and smart speakers. You could respond to users with text, speak back to them in a default or custom voice, provide search results, translate to other languages, and more.
