Figure 2From: Independent Component Analysis and Time-Frequency Masking for Speech Recognition in Multitalker ConditionsStructure of ICA with Postmasking. Here, stands for those ICA-based features that may be needed for mask estimation. All double arrows show the data flow of signal spectrograms, while single arrows indicate auxilliary information flow. The figure corresponds to the special case of two microphones and two estimated signals.Back to article page
