binaural proposed doa studyAbstract
Speaker localization for binaural microphone arrays has been widely studied for applications such as speech communication, video conferencing, and robot audition.
Many methods developed for this task, including the direct path dominance (DPD) test, share common stages in their processing, which include transformation using the short-time Fourier transform (STFT), and a direction of arrival (DOA) search that is based on the head related transfer function (HRTF) set.
In this paper, alternatives to these processing stages, motivated by human hearing, are proposed.
These include incorporating an auditory filter bank to replace the STFT, and a new DOA search based on transformed HRTF as steering vectors.
A simulation study and an experimental study are conducted to validate the proposed alternatives, and both are applied to two binaural DOA estimation methods; the results show that the proposed method compares favorably with current methods.
