BeamTransformer: Microphone Array-based Overlapping Speech Detection

Understand

We propose BeamTransformer, an efficient architecture to leverage beamformer's edge in spatial filtering and transformer's capability in context sequence modeling.

• BeamTransformer seeks to optimize modeling of sequential relationship among signals from different spatial direction.
• Overlapping speech detection is one of the tasks where such optimization is favorable.
• In this paper we effectively apply BeamTransformer to detect overlapping segments.
