It includes tables and graphs illustrating the relationship between various metrics such as average concatenative cost (Ca), Mean Opinion Score (MOS), and estimated MOS across different databases (Db1-Db4). The data suggests a correlation between objective measures of cost and subjective ratings of quality, with linear regression equations provided to model these relationships. The research appears to evaluate the effectiveness of different measurement approaches and their alignment with human perception of audio quality, possibly for improving speech codecs or audio rendering systems.",{"@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":40,"@type":76,"position":81},"https://docshare.wps.com/document/research-report/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/eurospeech/183127/",{"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/eurospeech/183127.png","ImageObject",300,407,{"name":92,"@type":93},"Emma
