ChirpArray: A low‐cost, easy‐to‐construct microphone array for long‐term ecoacoustic monitoring

Methods in Ecology and Evolution
Advances in passive acoustic monitoring (PAM) have highlighted the importance of recording devices and audio recognition techniques in ecosystem monitoring. This study introduces ChirpArray, a cost‐effective and easily assembled microphone array for long‐

Laser-Based Command Injection Attacks on Voice-Controlled Microphone Arrays

Transactions on Cryptographic Hardware and Embedded Systems
Voice-controlled (VC) systems, such as mobile phones and smart speakers, enable users to operate smart devices through voice commands. Previous works (e.g., LightCommands) show that attackers can trigger VC systems to respond to various audio commands ...

Real-Time Sound Source Localization for a Mobile Robot Based on the Guided Spectral-Temporal Position Method

International Journal of Advanced Robotic Systems, 2012
Sound source localization based on a microphone array for mobile robots faces great challenges because of factors such as uncertainty of the robot's movement, noise and reverberation, the requirements of a compact microphone array and so on.

Visualization of Broadband Sound Sources

MATEC Web of Conferences, 2016
In this paper the method of imaging of wideband audio sources based on the 2D microphone array measurements of the sound field at the same time in all the microphones is proposed. Designed microphone array consists of 160 microphones allowing to digitize

A Spectral Entropy-Based Metric for Evaluating Speech Perceptual Quality with Emphasis on Spectral Coherence

Signals
Distortion of speech in real-life communication is inevitable, affecting its quality. Conventionally, the effectiveness of a speech system in terms of the perceptual quality of the speech it produces has been assessed using a time-consuming subjective ...
