Abstract
A system and method for concurrent multi-path processing of audio signals for automatic speech recognition is presented. Audio information defining a set of audio signals may be obtained (). The audio signals may convey mixed audio content produced by multiple audio sources. A set of source-specific audio signals may be determined by demixing the mixed audio content produced by the multiple audio sources. Determining the set of source-specific audio signals may comprises providing the set of audio signals to both a first signal processing path and a second signal processing path (). The first signal processing path may determine a value of a demixing parameter for demixing the mixed audio content (). The second signal processing path may apply the value of the demixing parameter to the individual audio signals of the set of audio signals () to generate the individual source-specific audio signals ().
