Cognitive-driven speech enhancement using EEG-based auditory attention decoding for hearing aid applications (2020)
Abstract / truncated to 115 words
Identifying the target speaker in hearing aid applications is an essential ingredient to improve speech intelligibility. Although several speech enhancement algorithms are available to reduce background noise or to perform source separation in multi-speaker scenarios, their performance depends on correctly identifying the target speaker to be enhanced. Recent advances in electroencephalography (EEG) have shown that it is possible to identify the target speaker which the listener is attending to using single-trial EEG-based auditory attention decoding (AAD) methods. However, in realistic acoustic environments the AAD performance is influenced by undesired disturbances such as interfering speakers, noise and reverberation. In addition, it is important for real-world hearing aid applications to close the AAD loop by presenting on-line ... toggle 7 keywordsauditory attention decoding – brain computer interface – cognitive control – EEG – hearing aids – beamforming – speech enhancement
