Learning Binaural Spectrogram Features for Azimuthal Speaker Localization
Spatial localization of speech and other natural sounds with rich spectro-temporal structure is a computationally challenging task. It requires extraction of features which are informative about speaker’s position and yet invariant to sound level and spectral modulation present in the signal. This paper demonstrates that this can be achieved with Independent Component Analysis (ICA) applied to ...

متن کاملA spectrogram model for enhanced source localization and noise-robust ASR
This paper proposes a simple, computationally efficient 2-mixture model approach to discrimination between speech and background noise. It is directly derived from observations on real data, and can be used in a fully unsupervised manner, with the EM algorithm. A first application to sector-based, joint audio source localization and detection, using multiple microphones, confirms that the model...
