Description

Foundations of Voice and Speech Quality Perception starts out with the fundamental question of: “How do listeners perceive voice and speech quality and how can these processes be modeled?” Any quantitative answers require measurements. This is natural for physical quantities but harder to imagine for perceptual measurands. This book approaches the problem by actually identifying major perceptual dimensions of voice and speech quality perception, defining units wherever possible and offering paradigms to position these dimensions into a structural skeleton of perceptual speech and voice quality. The emphasis is placed on voice and speech quality assessment of systems in artificial scenarios. In principle, the usual over-simplified engineering approaches would fail to cover the general problem of speech-quality design. This book bridges the gap between the two diverse fields, engineering and humanities, and establishes the new research area of Voice and Speech Quality Perception.
