We study conversational latency in a controlled telephone setup to quantify its impact on perceived quality, dialogue dynamics, and EEG oscillations. Even modest one-way delays disrupted turn-taking and increased cognitive workload, reflected in lower quality ratings and changes in frontal theta/alpha activity. The results provide multi-modal evidence for stringent latency targets in voice services.
