Speaker Orientation-Aware Privacy Control to Thwart Misactivation of Voice Assistants

Zhang, S., Sabir, A., & Das, A. (2023, June 1).

By: S. Zhang n, A. Sabir n & A. Das n

author keywords: Voice assistant; Privacy control; Signal processing
topics (OpenAlex): Speech and Audio Processing; Music and Audio Processing; Speech Recognition and Synthesis
TL;DR: This paper proposes a device-free, non-obtrusive acoustic sensing system called HeadTalk, which leverages the user's head direction information and verifies that a human generates the sound to minimize accidental activations of VAs. (via Semantic Scholar)

VoicePM: A Robust Privacy Measurement on Voice Anonymity

Zhang, S., Li, Z., & Das, A. (2023, May 29).

By: S. Zhang n, Z. Li n & A. Das n

author keywords: Voice assistant; Voice anonymity; Privacy control
topics (OpenAlex): Speech Recognition and Synthesis; Speech and Audio Processing; Voice and Speech Disorders
TL;DR: This study develops a tradeoff metric to capture voice biometrics as well as different voice attributes and proposes VoicePM, a robust Voice Privacy Measurement framework, to study the feasibility of applying different state-of-the-art voice anonymization solutions to achieve the optimum tradeoff between privacy and utility.

A WiFi-based Home Security System

Zhang, S., Venkatnarayan, R. H., & Shahzad, M. (2020, December 1).

By: S. Zhang n, R. Venkatnarayan  n & M. Shahzad n 

topics (OpenAlex): Indoor and Outdoor Localization Technologies; Wireless Networks and Protocols; Bluetooth and Wireless Communication Technologies
TL;DR: A Wi Fi based security system that uses commodity WiFi devices, which most modern households already have, to perform the three primary tasks of typical home security systems, detected intrusions with over 95% accuracy and identified the exact door/window that moved with just 4.5% average error.

Evaluating Relationships between Perception-Reaction Times, Emergency Deceleration Rates, and Crash Outcomes using Naturalistic Driving Data

Wood, J. S., & Zhang, S. (2020, November 18). Transportation Research Record Journal of the Transportation Research Board.

By: J. Wood * & S. Zhang n

topics (OpenAlex): Traffic and Road Safety; Urban Transport and Accessibility; Statistical Methods and Bayesian Inference
TL;DR: This research developed predictive models for PRT and deceleration rate that could be used for roadway design and indicated that minimum design SSD values would increase by 10.5–129.2 ft, dependent on the design speed and SSD model used. (via Semantic Scholar)

Identification and Calculation of Horizontal Curves for Low-Volume Roadways Using Smartphone Sensors

Wood, J. S., & Zhang, S. (2018, April 27). Transportation Research Record Journal of the Transportation Research Board.

By: J. Wood * & S. Zhang n

topics (OpenAlex): Automated Road and Building Extraction; Infrastructure Maintenance and Monitoring; Traffic Prediction and Management Techniques
TL;DR: A low-cost mobile road inventory system for two-lane horizontal curves based on off-the-shelf smartphones capable of accurately detecting horizontal curves by exploiting a K-means machine learning technique and achieves high curve identification accuracy as well as high accuracy for calculating curve radius and superelevation.
