Compania Google a lansat actualizarea codec-ului audio Lyra 0.0.2, optimizat pentru a ob\u021bine calitatea maxim\u0103 a transmisiei vocale folosind canale foarte lente. Codec-ul a fost deschis la \u00eenceputul lunii aprilie, dar a fost disponibil \u00eempreun\u0103 cu o bibliotec\u0103 matematic\u0103 proprietar\u0103. \u00cen versiunea 0.0.2, aceast\u0103 lips\u0103 a fost remediat\u0103, iar pentru biblioteca men\u021bionat\u0103 a fost creat\u0103 o alternativ\u0103 deschis\u0103 \u2014 sparse_matmul, care, la fel ca \u0219i codec-ul, este distribuit\u0103 sub licen\u021ba Apache 2.0. Alte \u00eembun\u0103t\u0103\u021biri includ posibilitatea de a utiliza sistemul de construire Bazel cu compilatorul GCC \u0219i utilizarea acestei combina\u021bii \u00een mod implicit \u00een Linux \u00een loc de Bazel+Clang. <\/p>\n

S\u0103 ne amintim c\u0103, \u00een ceea ce prive\u0219te calitatea datelor vocei transmise la viteze reduse, Lyra dep\u0103\u0219e\u0219te semnificativ codec-urile tradi\u021bionale, care folosesc metode de procesare digital\u0103 a semnalelor. Pentru a ob\u021bine o calitate \u00eenalt\u0103 a transmisiei vocii \u00een condi\u021bii de volum limitat de informa\u021bii transmise, pe l\u00e2ng\u0103 metodele obi\u0219nuite de compresie a sunetului \u0219i de conversie a semnalelor, Lyra folose\u0219te un model de voce bazat pe un sistem de \u00eenv\u0103\u021bare automat\u0103, care permite recrearea informa\u021biilor lips\u0103 pe baza caracteristicilor tipice ale vocii. Modelul folosit pentru generarea sunetului a fost antrenat folosind c\u00e2teva mii de ore de \u00eenregistr\u0103ri audio cu voci \u00een peste 70 de limbi. Performan\u021ba implement\u0103rii propuse este suficient\u0103 pentru codificarea \u0219i decodificarea vocii \u00een timp real pe smartphone-uri de buget mediu, cu o \u00eent\u00e2rziere a semnalului de 90 de milisecunde.
