ABSTRACT
Evaluation of speech quality in modern telecommunication systems has become a primary concern. While novel coding and networking strategies provide increasingly fast, high-quality, and reliable services, acoustically induced effects like echo, reverberation, and some types of noise remain difficult issues to control. This chapter gives a brief overview of automatic assessment of acoustically degraded high-quality speech signals. After a basic overview of different quality assessment strategies, the chapter highlights relevant literature and standards on the topic, with focus on ITU documents. The text proceedswith recent contributions by the authors research group in full-and no-reference tools for automatic quality assessment of acoustically degraded full-band speech.
