-Different scenarios/use-cases require different optimizations that influence the behavior of the audio processing stack. For example, in telecommunications scenarios such as telephone calls, it is acceptable to have minor distortions in the audio signal after processing has been applied. This is because humans can continue to understand the speech with high accuracy. However, it is unacceptable and disruptive for a person to hear their own voice in an echo. This contrasts with speech processing scenarios, where distorted audio can adversely impact a machine-learned speech recognition model’s accuracy, but it is acceptable to have minor levels of echo residual.

 Processing is performed fully locally where the Speech SDK is being used. No audio data is streamed to Microsoft’s cloud services for processing by the Microsoft Audio Stack. The only exception to this is for the Conversation Transcription Service, where raw audio is sent to Microsoft’s cloud services for processing.
