MAGE logoSta­tis­ti­cal para­met­ric speech syn­the­sis, based on Hid­den Markov Mod­els has been demon­strated to be very effec­tive in syn­the­siz­ing high qual­ity, nat­ural and expres­sive speech. This tech­nique is also able to pro­vide high flex­i­bil­ity as a speech pro­duc­tion model and a small data­base foot­print.
Based on the exist­ing HTS engine, we devel­oped a stream­ing archi­tec­ture of the sys­tem, called performative-HTS or pHTS. On top of pHTS we devel­oped MAGE, a thread safe and engine inde­pen­dent layer of pHTS, that can be used in reac­tive speech syn­the­sis designs, (i.e. a design that can be often inter­rupted and can respond in real-time to requests).
Quan­ti­ta­tive eval­u­a­tions of the sys­tem show that the degra­da­tion of speech qual­ity in pHTS is small with ref­er­ence to HTS, even though pHTS has a delay of one pho­netic label only . These results are sup­ported by a sub­jec­tive and an objec­tive eval­u­a­tion, which con­firms that HTS and pHTS result­ing speech wave­forms can hardly be distinguished.
