Speaker Separation and Tracking System

Speaker Separation and Tracking System

Replicating human hearing in electronics under the constraints of using only twomicrophones (even withmore than two speakers) and the user carrying the device at all times (i.e., mobile device weighing less than 100 g) is nontrivial. Our novel contribution in this area is a two-microphone system that incorporates both blind source separation and speaker tracking. This system handles more than t...

Evolutive HMM for multi-speaker tracking system

Online blind speech separation using multiple acoustic speaker tracking and time-frequency masking

Separating speech signals of multiple simultaneous talkers in a reverberant enclosure is known as the cocktail party problem. In real-time applications online solutions capable of separating the signals as they are observed are required in contrast to separating the signals offline after observation. Often a talker may move, which should also be considered by the separation system. This work pr...

An Online Speaker Tracking System for Ambient Intelligence Environments

Ambient intelligence is an interdisciplinary paradigm which envisages smart spaces that provide services and adapt transparently to the user. As the most natural interface for human interaction, speech can be exploited for adaptation purposes in such scenarios. Low latency is required, since adaptation must be continuous. Most speaker tracking approaches found in the literature work offline, fu...
