1. 1. 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

3. 2. The /k/s, the /t/s, and the inbetweens : Novel approaches to examining the perceptual consequences of misarticulated speech

   Författare :Sofia Strömbergsson; David House; Åsa Wengelin; Benjamin Munson; KTH; []
   Nyckelord :HUMANIORA; HUMANITIES; speech perception; speech disorders; speech synthesis; speech analysis; Tal- och musikkommunikation; Speech and Music Communication;

   Sammanfattning : This thesis comprises investigations of the perceptual consequences of children’s misarticulated speech – as perceived by clinicians, by everyday listeners, and by the children themselves. By inviting methods from other areas to the study of speech disorders, this work demonstrates some successful cases of cross-fertilization. LÄS MER

4. 3. 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

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. Evaluation of nasal speech : a study of assessments by speech-language pathologists, untrained listeners and nasometry

   Författare :Karin Brunnegård; Jan van Doorn; Anette Lohmander; Fiona Gibbon; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hypernasality; auditory perceptual evaluation; reliability; nasometer; nasalance; Logopedics and phoniatrics; Logopedi och foniatrik;

   Sammanfattning : Excessive nasal resonance in speech (hypernasality) is a disorder which may have negative communicative and social consequences for the speaker. Excessive nasal resonance is often associated with cleft lip and palate, velopharyngeal impairment, dysarthria or hearing impairment. LÄS MER
