Speech segregation based on sound localization
At a cocktail party, one can selectively attend to a single voice and filter out all the other
acoustical interferences. How to simulate this perceptual ability remains a great challenge. This …

Binary and ratio time-frequency masks for robust speech recognition
A time-varying Wiener filter specifies the ratio of a target signal and a noisy mixture in a local
time-frequency unit. We estimate this ratio using a binaural processor and derive a ratio time…

Binaural tracking of multiple moving sources
This paper addresses the problem of tracking multiple moving sources using binaural input.
We observe that binaural cues are strongly correlated with source locations in time-…

Speech intelligibility in reverberation with ideal binary masking: Effects of early reflections and signal-to-noise ratio threshold
N Roman, J Woodruff - The Journal of the Acoustical Society of …, 2013 - pubs.aip.org
Ideal binary masking is a signal processing technique that separates a desired signal from
a mixture by retaining only the time-frequency units where the signal-to-noise ratio (SNR) …

Boosting construction project timeline: The case of critical chain project management (CCPM)
Critical Chain Project Management (CCPM) has emerged as a notable approach in recent
years for improving time management in construction projects. This methodology focuses on …

Binaural segregation in multisource reverberant environments
In a natural environment, speech signals are degraded by both reverberation and concurrent
noise sources. While human listening is robust under these conditions using only two ears, …

Intelligibility of reverberant noisy speech with ideal binary masking
N Roman, J Woodruff - The Journal of the Acoustical Society of …, 2011 - pubs.aip.org
For a mixture of target speech and noise in anechoic conditions, the ideal binary mask is
defined as follows: It selects the time-frequency units where target energy exceeds noise …

Pitch-based monaural segregation of reverberant speech
In everyday listening, both background noise and reverberation degrade the speech signal.
Psychoacoustic evidence suggests that human speech perception under reverberant …
