1. 1. Mapping Individual Voice Quality over the Voice Range : The Measurement Paradigm of the Voice Range Profile

   Författare :Peter Pabon; Sten Ternström; Maria Södersten; Ingo Titze; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Voice Range Profile VRP ; Phonetogram; Voice Field; Voice quality; Singing voice; Voice synthesis; Clinical voice assessment; Sound level measurement; Maximum Entropy; Tal- och musikkommunikation; Speech and Music Communication;

   Sammanfattning : The acoustic signal of voiced sounds has two primary attributes: fundamental frequency and sound level. It has also very many secondary attributes, or ‘voice qualities’, that can be derived from the acoustic signal, in particular from its periodicity and its spectrum. LÄS MER

3. 2. Towards conversational speech synthesis : Experiments with data quality, prosody modification, and non-verbal signals

   Författare :Bajibabu Bollepalli; Joakim Gustafsson; Jonas Beskow; Matthew Aylett; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Speech synthesis; MPEG compression; Voice Conversion; Artificial Neural Net- works; Laughter synthesis; HTS; Computer Science; Datalogi;

   Sammanfattning : The aim of a text-to-speech synthesis (TTS) system is to generate a human-like speech waveform from a given input text. Current TTS sys- tems have already reached a high degree of intelligibility, and they can be readily used to read aloud a given text. For many applications, e.g. LÄS MER

4. 3. The Voice Source in Speech Communication - Production and Perception Experiments Involving Inverse Filtering and Synthesis

   Författare :Christer Gobl; KTH; []
   Nyckelord :Voice source dynamics; glottal source parameters; source-filter interaction; voice quality; phonation; perception; affect; emotion; mood; attitude; paralinguistic; inverse filtering; knowledge-based; formant synthesis; LF model; fundamental frequency;

   Sammanfattning : This thesis explores, through a number of production andperception studies, the nature of the voice source signal andhow it varies in spoken communication. Research is alsopresented that deals with the techniques and methodologies foranalysing and synthesising the voice source. LÄS MER

5. 4. Perception, Analysis and Synthesis of Speaker Age

   Författare :Susanne Schötz; Fonetik; []
   Nyckelord :HUMANIORA; HUMANITIES; phonology; perceptual cues; speaker age; automatic speaker recognition; acoustic analysis; acoustic correlates; data-driven; Phonetics; formant synthesis; Fonetik; fonologi; Technological sciences; Teknik;

   Sammanfattning : Speaker age is an important paralinguistic feature in speech which has to be considered in the study of phonetic variation. Knowledge about this feature may be used to improve speech technology applications, e.g. automatic speech recognition and speech synthesis. LÄS MER

7. 5. Recognition and Evaluation by Video Synthesis Methods and Symmetry Features

   Författare :Dereje Teferi Lemma; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Biometrics; eye detection; video synthesis; liveness detection; camera calibration; damascening; Generalized Structure Tensor; symmetry codes;

   Sammanfattning : Biometrics is being increasingly utilized for person authentication. It requires little or no efforts from the user as compared to traditional non-biometric systems where the user has to memorize PIN codes and passwords or carry pass cards and keys that can be easily forgotten or lost.
