Developed and delivered a new Speech-Driven Context-Aware Voice Activity Detection (SDCAVAD) sample for the microsoft/Windows-driver-samples repository, expanding the audio processing capabilities available to Windows driver developers. The work introduced Audio Processing Objects (APOs) and event detector adapters, enabling context-aware voice activity detection within the sample ecosystem. Implemented in C++ with a focus on COM programming and Windows driver development, the feature was structured as a dedicated, extensible module to support future enhancements and broader testing. The contribution provided a clean, single-commit addition, facilitating traceability and maintainability for ongoing improvements in audio processing sample architectures.
