ITU-T P.501 AMD 3-2015 Test signals for use in telephonometry Amendment 3: New Annex D – Speech files with male/female sentences prepared for use with perceptual based objective speech quality prediction (Study Group 12)
This Recommendation intends to specify the intermediate reference system (IRS) to be used for defining loudness ratings.The description should be sufficient to enable equipment having the required characteristics to be reproduced in different laboratories and maintained to standardized performance.Amendment 3 to Recommendation ITU-T P.501 (2012) introduces Annex D and updates the References clause to accommodate new entries cited.It includes a set of test speech signals based on Annex B,which are composed of 6 s female-male combinations.The signals are especially prepared for use in conjunction with ITU-T P.800-based applications and perceptual based objective models using ITU-T P.800-conformant speech samples.
