1. 1. Disfluency in Swedish human–human and human–machine travel booking dialogues

   Författare :Robert Eklund; Lars Ahrenberg; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Speech; Speech disorders; Speech intelligibility; Speech perception; Computer linguistics; phonetic; Man-computer-interaction; Computational linguistics; Datorlingvistik;

   Sammanfattning : This thesis studies disfluency in spontaneous Swedish speech, i.e., the occurrence of hesitation phenomena like eh, öh, truncated words, repetitions and repairs, mispronunciations, truncated words and so on. LÄS MER

3. 2. Found speech and humans in the loop : Ways to gain insight into large quantities of speech

   Författare :Per Fallgren; Jens Edlund; Fred Cummins; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Found data; found speech; human-in-the-loop; sound browsing; dimensionality reduction; visualization; crowdsourcing; Tal- och musikkommunikation; Speech and Music Communication;

   Sammanfattning : Found data - data used for something other than the purpose for which it was originally collected - holds great value in many regards. It typically reflects high ecological validity, a strong cultural worth, and there are significant quantities at hand. However, it is noisy, hard to search through, and its contents are often largely unknown. LÄS MER

4. 3. Mining Speech Sounds : Machine Learning Methods for Automatic Speech Recognition and Analysis

   Författare :Giampiero Salvi; Björn Granström; Torbjørn Svendsen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; speech; machine learning; data mining; signal processing; Computer science; Datavetenskap;

   Sammanfattning : This thesis collects studies on machine learning methods applied to speech technology and speech research problems. The six research papers included in this thesis are organised in three main areas. The first group of studies were carried out within the European project Synface. LÄS MER

5. 4. 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

7. 5. Automatic speaker verification on site and by telephone: methods, applications and assessment

   Författare :Håkan Melin; Björn Granström; Mats Blomberg; Josef Bigün; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; speaker recognition; speaker verification; speech technology; biometrics; access control; speech corpus; variance estimation; Information and language technology; Informations- och språkteknologi;

   Sammanfattning : Speaker verification is the biometric task of authenticating a claimed identity by means of analyzing a spoken sample of the claimant's voice. The present thesis deals with various topics related to automatic speaker verification (ASV) in the context of its commercial applications, characterized by co-operative users, user-friendly interfaces, and requirements for small amounts of enrollment and test data.
