Google ha pubblicato un aggiornamento del codec audio Lyra 0.0.2, ottimizzato per garantire la massima qualit\u00e0 nella trasmissione vocale su canali estremamente lenti. Il codec era stato rilasciato all'inizio di aprile, ma era fornito con una biblioteca matematica proprietaria. Nella versione 0.0.2, questo problema \u00e8 stato risolto e per la suddetta biblioteca \u00e8 stata creata un'alternativa open source \u2014 sparse_matmul, che, come il codec stesso, \u00e8 distribuita sotto la licenza Apache 2.0. Tra gli altri miglioramenti si segnala la possibilit\u00e0 di utilizzare il sistema di build Bazel con il compilatore GCC, rendendo questa combinazione la predefinita su Linux invece di Bazel+Clang. <\/p>\n
Ricordiamo che la qualit\u00e0 dei dati vocali trasmessi a basse velocit\u00e0 con Lyra supera significativamente quella dei tradizionali codec, che utilizzano metodi di elaborazione del segnale digitale. Per ottenere un'alta qualit\u00e0 nella trasmissione della voce in condizioni di volume di dati limitato, oltre ai consueti metodi di compressione audio e di elaborazione dei segnali, Lyra utilizza un modello di riconoscimento vocale basato su un sistema di apprendimento automatico, capace di ricreare le informazioni mancanti sulla base delle caratteristiche tipiche della voce. Il modello utilizzato per generare il suono \u00e8 stato addestrato con migliaia di ore di registrazioni vocali in oltre 70 lingue. Le prestazioni della soluzione proposta sono sufficienti per codificare e decodificare la voce in tempo reale su smartphone di fascia media, con un ritardo di trasmissione del segnale di circa 90 millisecondi. \u041a\u043e\u043c\u043f\u0430\u043d\u0438\u044f Google \u043e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043b\u0430
