Syed Muhammad Nabeel Zaidi

- Analyzed system and component requirements, models, and C code for deriving and validating relevant test conditions. - Created and maintained test specifications, test environments, and model-based test cases with TPT. - Conducted MIL and SIL tests, evaluated the results, and documented the observed software behavior. - Created and tracked error tickets (e.g. in Jira, Polarion) and supported error analysis. - Prepared test results and created test reports as well as status overviews for project.

- Analyzed and evaluated technical concepts and system solutions in the areas of audio, video, tuner, and UI. - Planned, conducted, and documented functional and vehicle tests on control units. - Captured and documented errors in detail; created maturity reports for quality evaluation. - Evaluated the system quality at the overall vehicle level, including functional requirements. - Verified communication interfaces (CAN, MOST) for stability and functionality at the network level.

- Analyzed standard pitch estimation methods and harmony-based speech functions, taking into account longer window lengths. - Implemented spectral refinement techniques to compensate for low spectral resolution in short windows and used established methods for VAD and pitch estimation. - Analyzed extended autocorrelation functions (Extended ACF) with explicit consideration of short window lengths

- Designed VAD (Voice Activity Detection) module in MATLAB as part of Loudness normalization algorithm - Added best suited speech features for speech/other discrimination - Based on Performance criteria, rated features and documented the results - Implemented and tested promising feature combining strategies - Selected final feature set and feature-combining algorithm

- Responsible for Operations & Access Network Services - Global Information System (GIS) Survey of Complete Access Network - Developed and implemented technical reports for business requirements
