Speech Recognition with Microphone Arrays

open access: yes, 2001
Microphone arrays can be advantageously employed in Automatic Speech Recognition (ASR) systems to allow distant-talking interaction. Their beamforming capabilities are used to enhance the speech message, while attenuating the undesired contribution of ...

TOWARDS REAL-TIME SOURCE COUNTING BY ESTIMATION OF COHERENT-TO-DIFFUSE RATIOS FROM AD-HOC MICROPHONE ARRAY RECORDINGS

open access: yes, 2017
Coherent-to-diffuse ratio (CDR) estimates over short time frames are utilised for source counting using ad-hoc microphone arrays to record speech from multiple participants in scenarios such as a meeting. It is shown that the CDR estimates obtained at ad-

A perspective on automated rapid eye movement sleep assessment

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Rapid eye movement sleep is associated with distinct changes in various biomedical signals that can be easily captured during sleep, lending themselves to automated sleep staging using machine learning systems. Here, we provide a perspective on the critical characteristics of biomedical signals associated with rapid eye movement sleep and how ...

Teacher Perspectives of Student Engagement in Data Practice Instruction: Two Classroom Conditions

open access: yesSchool Science and Mathematics, EarlyView.
ABSTRACT This study examines high school science teachers' perceptions of student engagement in data practices across two instructional contexts: a scaffolded, student‐centered environment using the Science Practices Innovation Notebook (SPIN) and a business‐as‐usual (BAU) teacher‐led investigation.

Regional changes in cerebral blood flow between the upright and supine posture and over 3 days of bed rest

open access: yesExperimental Physiology, EarlyView.
Abstract A reduction in cerebral blood flow (CBF) has been observed during spaceflight and bed rest. We aimed to examine the magnitude and regional heterogeneity of the decrease in CBF during bed rest compared to posture changes on Earth. Seventeen participants (age, 29 ± 9 years, 7 females) were studied in the upright and supine posture and over 3 ...
