1. Umbert Morist, Martí. Expression control of singing voice synthesis: modeling pitch and dynamics with unit selection and statistical approaches.

Degree: Departament de Tecnologies de la Informació i les Comunicacions, 2016, Universitat Pompeu Fabra

Aquesta tesi es centra en el control dels sintetitzadors de veu cantada per aconseguir una expressivitat natural semblant a la d'un cantant real. Hi ha moltes característiques que s'haurien de controlar per aconseguir una expressivitat natural relacionades amb la melodia, la dinàmica, el ritme i el timbre. En aquesta tesi ens centrem en el control de la freqüència fonamental i de la dinàmica amb un sistema basat en selecció d'unitats, dos sistemes estadístics, i un sistema híbrid. Aquests sistemes són entrenats amb dues possibles bases de dades expressives que hem dissenyat, enregistrat i etiquetat. Hem definit les unitats bàsiques a partir de les quals les bases de dades s'han construit i que són seqüències de tres notes o silencis. La nostra avaluació perceptual compara els sistemes proposats amb altres sistemes per tal de veure com els podem relacionar. L'avaluació objectiva es centra en l'eficiència dels sistemes.

2. Coleman, Graham Keith. Descriptor control of sound transformations and mosaicing synthesis.

Degree: Departament de Tecnologies de la Informació i les Comunicacions, 2016, Universitat Pompeu Fabra

El mostreig, com a tècnica musical o de síntesi, és una manera de reutilitzar expressions musicals enregistrades. En aquesta dissertació s’exploren estratègies d’ampliar la síntesi de mostreig, sobretot la síntesi de “mosaicing”. Aquesta última tracta d’imitar un senyal objectiu a partir d’un conjunt de senyals font, transformant i ordenant aquests senyals en el temps, de la mateixa manera que es faria un mosaic amb rajoles trencades. Una d’aquestes ampliacions de síntesi consisteix en el control automàtic de transformacions de so cap a objectius definits a l’espai perceptiu. L’estratègia elegida utilitza models que prediuen com es transformarà el so d’entrada en funció d’uns paràmetres seleccionats. En un cas, els models són coneguts, i cerques númeriques es poden fer servir per trobar paràmetres suficients; en l’altre, els models són desconeguts i s’han d’aprendre a partir de les dades. Una altra ampliació es centra en el mostreig en si. Mesclant múltiples sons a la vegada, potser és possible fer millors imitacions, més específicament millorar l’harmonia del resultat, entre d’altres. Tot i així, utilitzar múltiples mescles crea nous problemes computacionals, especialment si propietats com la continuïtat, important per a la síntesis de mostreig d’alta qualitat, han de ser preservades. En aquesta tesi es presenta un nou sintetitzador mosaicing que incorpora tots aquests elements: control automàtic de transformacions de so fent servir models, mescles a partir de descriptors d’harmonia i timbre perceptuals, i preservació de la continuïtat del context de mostreig i dels paràmetres de transformació. Fent servir proves d’escolta, l’algorisme híbrid proposat va ser comparat amb algorismes clàssics i contemporanis: l’algorisme híbrid va donar resultats positius a una varietat de mesures de qualitat.

3. Muševič, Sašo. Non-stationary sinusoidal analysis.

Degree: Departament de Tecnologies de la Informació i les Comunicacions, 2013, Universitat Pompeu Fabra

Many types of everyday signals fall into the non-stationary sinusoids category. A large family of such signals represent audio, including acoustic/electronic, pitched/transient instrument sounds, human speech/singing voice, and a mixture of all: music. Analysis of such signals has been in the focus of the research community for decades. The main reason for such intense focus is the wide applicability of the research achievements to medical, financial and optical applications, as well as radar/sonar signal processing and system analysis. Accurate estimation of sinusoidal parameters is one of the most common digital signal processing tasks and thus represents an indispensable building block of a wide variety of applications. Classic time-frequency transformations are appropriate only for signals with slowly varying amplitude and frequency content - an assumption often violated in practice. In such cases, reduced readability and the presence of artefacts represent a significant problem.
