[Invited Lecture] Measurement method of speech listening performance under various listening environments based on speech and word intelligibility

Abstract (in Japanese) (See Japanese page) 
(in English) The effectiveness in conveying a message is an important consideration when transmitting speech information via a communications system. We focus on outdoor public address systems, which can convey information throughout a wide listening area. In these systems, the effect of long-path echoes, which are generated by the reflections from mountains and surrounding structures, can have a significant impact. To evaluate this, it is important to use indexes that can directly reflect the degree of speech understanding by the listeners. To this end, we proposed the familiarity-controlled word lists 2003 (FW03) and 2007 (FW07). In this report, I present the results of our research towards the robust transmission of speech information in the presence of long-path echoes by using the proposed FW07 word lists. Further, I introduce our results towards the development of an evaluation method of speech understanding based on sentence intelligibility: a Japanese version of the Oldenburg sentence test (OLSA).
