It outlines reference systems, objective measuring apparatus, and specific measurements related to speech loudness. The document details various methodologies for both objective and subjective evaluations of speech and audiovisual quality in multimedia services, including quality of service (QoS) aspects of IP end-points and communications involving vehicles. It also covers models and tools for assessing the quality of streamed media and telemeeting sessions, along with statistical analysis, evaluation, and reporting guidelines for quality measurements. The document presents two tables detailing subjective and objective quality assessment scales, such as MOS-LQSy, MOS-CQSy, MOS-TQSy for subjective measures, and MOS-LQOy, MOS-CQOy, MOS-TQOy for objective measures.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":30,"@type":76,"position":81},"https://docshare.wps.com/document/technology/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/p800-2016-methods-for-objective-and-subjective-assessment-of-speech-quality/183170/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/p800-2016-methods-for-objective-and-subjective-assessment-of-speech-quality/183170.png","ImageObject",300,407,{"name":92,"@type":93},"Bill Black","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-26","2026-09-02",true,{"@type":102,"interactionType":103,"userInteractionCount":39},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What are the main types of speech quality assessment methods discussed in this document?","Question",{"text":112,"@type":113},"The document discusses both objective and subjective methods for assessing speech quality.
