Article Synopsis
- Time delay estimation (TDE) is crucial for speaker localization and tracking but often relies on the assumption that speech signals have a Gaussian distribution.
- This paper explores how TDE performance is affected by different speech distribution models, addressing issues like noise and reverberation that impact sound capture from far-field microphones.
- It proposes a new TDE method using generalized Gaussian distributions and derives entropy expressions that show TDE results can remain consistent regardless of the speech distribution model, given the same covariance matrix.
