- The main goal of our current research is the development of the Swedish prosody model. In our analysis of discourse and dialogue intonation, we are exploiting model-based resynthesis. By comparing synthesized default and fine-tuned pitch contours for the dialogues under study, we are able to isolate relevant intonation patterns. This analysis of intonation is related to an independent modelling of topic structure consisting of lexical-semantic analysis and text segmentation. Some results from our model-based acoustic analysis are presented, and its implementation in text-to-speech-synthesis is discussed.

Text-to-intonation in spontaneous Swedish
- 1997

Konferensbidrag (refereegranskat)abstract
- This paper deals with a number of aspects of intonation in spontaneous dialogues in a language technology perspective. The key topics to be addressed are: I) the analysis of global intonation and its interaction with textual structure, II) the implementation of global and textual aspects of discourse intonation in an analysis-by-synthesis environment. We present models for the analyses of intonation and textual content in spontaneous conversations in Swedish. The models are implemented in a computational environment, making it possible to generate F0 contours, which can be imposed on a speech waveform using the PSOLA technique. The result is a text-to-intonation system, where textual and lexical analyses automatically generate hypothetical intonation contours, which can through resynthesis, and eventually be used in a text-to-speech system.

Vowel reduction and the perception of words
- 1998

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This study deals with listeners' ability to identify linguistic units from linguistically incomplete stimuli and relates this to the potentiality of vowel reduction in a word. Synthetic speech was used to produce stimuli that were similar to real words, but where the vowel in the pre-stress syllable was excluded. Listeners then performed a lexical decision test, where they had to decide whether a stimulus sounded like a word or not. The effects of the identity of the removed vowel and of features of the consonants adjacent to the removed vowel were then examined. For type of vowel, lower word rates where found for words with the vowels /a/ and /o/, whereas words with nasals after the reduced vowel tended to result in higher word rates.

Discourse markers and the segmentation of spontaneous speech - The case of Swedish men 'but/and/so'
- 1999
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Prosodic and lexical correlates of ‘clause-like’ and ‘paragraph-like’ boundaries associated with the Swedish discourse marker men ‘but/and/so’ are examined. Men-tokens in spontaneous monologues were labelled as to their boundary-status, first using text-only data. The ‘strong’ tokens (labelled identically by all labellers) were subsequently seen to be correlated with clear differences in the prosodic and lexical parameters examined. This tendency was not found for the corresponding ‘weak’ tokens which were subsequently relabelled using both text and speech nor for the data-base as a whole. A test using a neural network trained using strong tokens is seen to be able to correctly categorize 90% of the strong men-tokens as to their associated boundary-type. The results show that discourse markers along with their prosodic and lexical correlates constitute a constellation of important information for understanding how segmentation of speech is produced and understood

Prosodic Correlates of Information Structure in Swedish Human-Human Dialogues
- 1999

Ingår i: EUROSPEECH'99. ; 1, s. 29-32
-
Konferensbidrag (refereegranskat)abstract
- Investigation of travel agent (~System) Task-related utterances reveals intonational contours where focal accents occur on information given previously in the dialogue by the client (~User). The accentuation can be related to the interactive nature of dialogue where the information holder picks up on a Task-related topic introduced by the client and comments on it in an engaged manner.
