Single channel speech enhancement in the modulation domain: New insights in the modulation channel selection framework
Jesper Bunsow Boldt, Andreas T. Bertelsen, Fredrik Gran, Søren Jørgensen, Torsten Dau · 2015
Recently, the ideal binary mask has been introduced in the modulation domain by extending the ideal channel selection method to modulation channel selection [1]. This new method shows substantial improvement in speech intelligibility but less than its predecessor despite the higher complexity. Here, we extend the previous finding from [1] and provide a more direct comparison of binary masking in the modulation domain with binary masking in the time-frequency domain. Subjective and objective evaluations are performed and provide additional insight into modulation domain processing.
