Broadband oriented-noise masks were used to assess the orientation properties of spatial-context suppression in 'general' viewing conditions (i.e., a fixated, large field of 'naturalistic' noise). Suppression was orientation-tuned with a Gaussian shape and bandwidth of 40 degrees that was consistent across test orientation (0 degrees, 45 degrees, 90 degrees, and 135 degrees). Strength of suppre...

Speaker recognition in mobile devices suffers from poor performance in noisy environments, necessitating the use of noisesuppression algorithms. These typically apply time-frequency masks – optimised on the signal statistics – to the noisy signal spectrum, suppressing the noise components while preserving the speech. Studies in the field of speech recognition demonstrate that ideal time-frequen...
