However, there is an increasing  interest in more expressive speech synthesisers for many new  applications. Giving the synthesiser the  ability to produce speech in a variety of styles  is a way to gain this expressiveness. Speech in  conversations is the most widely used  type of speech. Therefore, more than other aspects,  text-to-speech systems do need  to deal with elements that differentiate between reading and  conversation. This thesis focuses on describing the characteristic elements of conversational speech and    proposing models to synthesise them.      conversational speech differs significantly from reading aloud due to the inclusion of a variety of  rosodic resources that affect the rhythm of the utterances. These resources are, in fact, strategies to  achieve communicative tasks between the speaker and the addressee. One type of strategy is disfluency.  they are very frequent in normal speech, and in contrast to what one might expect, they carry information  and are useful for human communication. Other characteristic elements of conversational    speech are closed defined phrases that are repeated through speech and that carry affective rather than  propositional information.         i present an analysis of three different corpora. One is very similar to the most widely used corpora  in the literature for the study of disfluencies. It consists of a set of conversations. Another one was  recorded for machine translation and consists of a set of speeches. The third one was recorded from  ill-formed sentences. These are sentences generated by automatic systems with incorrect syntactic  structures. The corpus with the highest number of disfluencies is the conversational one. This sup ports  the claim that disfluencies are not related to problems in speaking or planning the discourse, but are  inherent to conversations.         disfluencies are disruptions of the speech flow, and they can be seen as discontinuities. It is  reasonable to assume that the prosody will be different from that expected for the same elements within a  fluent sentence only around such disconti nuities. Speech is fluent between discontinuities; thus, we can  define regions within which speech is fluent and name them fluency regions. Following the previous  hypothesis, considering that the elements in a disfluency are fluent within the correct context, it implies  there exists a sentence where we could insert an element of a disfluency and the sentence is still erceived  as fluent. We refer to this sentence as the underlying fluent sentence. The use of this assumption is  supported by studying the impact of disfluencies in a sentence on the speech rate and pitch. Findings  show that the inclusion of disfluencies only generates local modifications around fluency    boundaries with respect to the underlying fluent sentences.         the prosodic parameters that better describe fluency boundaries have been identified for each  type of conversational elements: hesitation, repetitions, filled pauses and wrappers. Regression models  are proposed to predict the prosody of these elements. The approach proposed in this thesis, which relies  on the underlying fluent sentence assumption, can take advantage of prosodic models trained on fluent    speech. Thus, there is no need to re-train the prosodic models.<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos acad\u00e9micos de la tesis doctoral \u00ab<strong>On the energy efficiency of cooperative wireless networks<\/strong>\u00ab<\/h3>\n<ul>\n<li><strong>T\u00edtulo de la tesis:<\/strong>\u00a0 On the energy efficiency of cooperative wireless networks <\/li>\n<li><strong>Autor:<\/strong>\u00a0 Jes\u00fas G\u00f3mez Vilardeb\u00f3 <\/li>\n<li><strong>Universidad:<\/strong>\u00a0 Polit\u00e9cnica de catalunya<\/li>\n<li><strong>Fecha de lectura de la tesis:<\/strong>\u00a0 14\/07\/2009<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3>Direcci\u00f3n y tribunal<\/h3>\n<ul>\n<li><strong>Director de la tesis<\/strong>\n<ul>\n<li>Ana Isabel P\u00e9rez Neira<\/li>\n<\/ul>\n<\/li>\n<li><strong>Tribunal<\/strong>\n<ul>\n<li>Presidente del tribunal: Miguel angel Lagunas hern\u00e1ndez <\/li>\n<li>mischa Dohler (vocal)<\/li>\n<li>Antonio s Kalis (vocal)<\/li>\n<li>francesc xavier Mestre pons (vocal)<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tesis doctoral de Jes\u00fas G\u00f3mez Vilardeb\u00f3 Currently, speech synthesisers sound natural when reading text aloud.
