AI models leverage room acoustics for speaker distance estimation

Researchers have investigated how single-channel speaker distance estimation models utilize room impulse responses. Their analysis revealed that while models can extract reverberation-based cues, early reflections are the most informative component when time calibration is absent. However, with time calibration, the model relies solely on propagation delay for accurate distance estimation, achieving significantly better results. AI
