A WaveRT miniport optionally implements this interface to be advised of write progress from the OS and to return precise stream position. Several of the driver routines return Windows performance counter timestamps reflecting the time at which samples are captured or presented by the device. In devices that have complex DSP pipelines and signal processing, calculating an accurate timestamp may be challenging and should be done thoughtfully. The timestamps should not simply reflect the time at which samples were transferred to or from the OS to the DSP.

This section describes the OS and driver interaction for burst reads. Two burst example read scenarios are discussed. The timestamps identify the sampling instant of the captured samples. The driver also returns the performance counter value that corresponds to the sampling instant of the first sample in the packet.

Note that this performance counter value might be relatively old, depending on how much capture data has been buffered within the hardware or driver outside of the WaveRT buffer. If there is more unread buffered data available the driver either: i. Immediately transfers that data into the available space of WaveRT buffer i. Or, ii. Programs hardware to burst the next packet into the available space of the WaveRT buffer, returns false for MoreData, and later sets the buffer event when the transfer completes.

The OS waits for the next buffer notification event. The wait might terminate immediately if the driver set the buffer notification in step 2c. If the driver did not immediately set the event in step 2c , the driver sets the event after it transfers more captured data into the WaveRT buffer and makes it available for the OS to read.

If the OS fails to create a stream on the pin before the buffer overflows then the driver may end the internal buffering activity and free associated resources.

Wake-on-Voice WoV enables the user to activate and query a speech recognition engine from a low power state to a full power state with screen on by saying a certain keyword, such as "Hey Contoso.

This feature allows for the device to be always listening for the user's voice while the device is idle and the screen is off. This is due to listening mode which uses much less power compared to normal microphone recording.

WoV allows for chained speech phrase like "Hey Contoso, when's my next appointment" to invoke a response from a voice assistant in a hands-free manner. The audio stack is responsible for communicating the wake data speaker ID, keyword trigger, context information on confidence level as well as notifying interested clients that the keyword has been detected.

To start developing a voice assistant for Windows, you will need to make sure you have the proper development environment.

Some resources necessary for a completely customized voice agent on Windows will require resources from Microsoft. The UWP Voice Assistant Sample provides sample versions of these resources for initial development and testing, so this section is unnecessary for initial development.

Follow the instructions in the readme to run the app and enter your credentials. Once you've received your Limited Access Feature token and bin file from Microsoft, you can begin on your own voice assistant on Windows.
