A deep analysis and a diagnosis of the unit selection algorithm (a lattice search algorithm) is provided. The importance of having the optimal solution is discussed and a new unit selection implementation based on a A* algorithm is presented. The IRISA TTS system, built for the study, is also presented. Three cost function enhancements are also presented. The first one is a new way ¿ in the target cost ¿ to minimize important spectral differences by selecting sequences of candidate units that minimize a mean cost instead of an absolute one. This cost is tested on a phonemic duration distance but is applicable to others. Our second proposition is a target sub-cost addressing intonation. It is based on coefficients extracted through a generalized version of Fujisaki¿s command-response model. This model features gamma functions modeling F0 called atoms. Finally, our third contribution concerns a penalty system that aims at enhancing the concatenation cost. This system is tempered by a fuzzy function that allows to soften penalties for units presenting low concatenation costs.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783639560329\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783639560329","offer_id":39440227729501,"sku":"9783639560329","price":48.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/3d075535-4b83-4041-acc0-8ccb5d36755e.jpg?v=1773207482","url":"https:\/\/shop.autorenwelt.de\/en\/products\/study-of-unit-selection-text-to-speech-synthesis-algorithms-von-david-guennec","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
