I-Google ishicilele ukukhishwa kwe-codec yomsindo ye-Lyra 1.3, okuhloswe ngayo ukuzuza ukudluliswa kwezwi kwekhwalithi ephezulu ngaphansi kwezimo zenani elilinganiselwe lolwazi oludlulisiwe. Ikhwalithi yenkulumo ku-bitrate engu-3.2 kbps, 6 kbps kanye no-9.2 kbps uma usebenzisa i-Lyra codec cishe ilingana nama-bitrate angu-10 kbps, 13 kbps no-14 kbps uma usebenzisa i-Opus codec. Ukuze uxazulule le nkinga, ngaphezu kwezindlela ezivamile zokucindezelwa komsindo nokuguqulwa kwesignali, i-Lyra isebenzisa imodeli yenkulumo esekelwe ohlelweni lokufunda lomshini, olukuvumela ukuthi udale kabusha ulwazi olulahlekile ngokusekelwe kuzici zenkulumo ezivamile. Ukuqaliswa kwekhodi yesithenjwa kubhalwe ku-C++ futhi kusatshalaliswa ngaphansi kwelayisensi ye-Apache 2.0.
Ngokungafani nokukhishwa okuklanywe kabusha kwe-Lyra 1.2 okuhlongozwe ngo-Okthoba, okuhunyushelwe kusakhiwo esisha senethiwekhi ye-neural, inguqulo 1.3 ithuthukisa imodeli yokufunda yomshini ngaphandle kwezinguquko zezakhiwo. Inguqulo entsha isebenzisa ama-integer angu-32 esikhundleni sezinombolo zamaphoyinti angu-8-bit ukuze igcine izisindo futhi yenze imisebenzi ye-arithmetic, okuholela ekuncipheni ngo-43% kosayizi wemodeli kanye nokusheshisa okungu-20% uma kuhlolwa ku-smartphone ye-Pixel 6 Pro. Ikhwalithi yenkulumo iye yagcinwa ezingeni elifanayo, kodwa ifomethi yedatha edlulisiwe ishintshile futhi ayihambisani nokukhishwa kwangaphambilini.
