On final rises and fall-rises in German and Swedish

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This study explores the intonational signalling of a ‘request address’ in German and Swedish. Data from 16 speakers (9 Germans, 7 Swedes) were elicited under controlled conditions, and intonation contours produced on the test phrase “Wallander?” were classified according to their phrase-final pattern. Both ‘rises’ and ‘fall-rises’ were produced frequently by both Germans and Swedes, which is in line with Ohala’s frequency code, but challenging for the Lund model of Swedish intonation.

- Our recent work within the research projectSIMULEKT (Simulating Intonational Varieties of Swedish) involves a pilot perceptiontest, used for detecting tendencies in humanclustering of Swedish dialects. 30 Swedishlisteners were asked to identify the geographical origin of 72 Swedish native speakers by clicking on a map of Sweden. Resultsindicate for example that listeners from thesouth of Sweden are generally better at recognizing some major Swedish dialects thanlisteners from the central part of Sweden.

Speech technology in the European project MonAMI
- 2008

Ingår i: Proceedings of FONETIK 2008. - Gothenburg, Sweden : University of Gothenburg. - 9789197719605 ; , s. 33-36

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper describes the role of speech and speech technology in the European project MonAMI, which aims at “mainstreaming ac-cessibility in consumer goods and services, us-ing advanced technologies to ensure equal ac-cess, independent living and participation for all”. It presents the Reminder, a prototype em-bodied conversational agent (ECA) which helps users to plan activities and to remember what to do. The prototype merges speech technology with other, existing technologies: Google Cal-endar and a digital pen and paper. The solution allows users to continue using a paper calendar in the manner they are used to, whilst the ECA provides notifications on what has been written in the calendar. Users may also ask questions such as “When was I supposed to meet Sara?” or “What’s on my schedule today?”

Knowledge-Rich Model Transformations for SpeakerKnowledge-Rich Model Transformations for Speaker Normalization in Speech Recognition

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- In this work we extend the test utterance adaptationtechnique used in vocal tract length normalizationto a larger number of speaker characteristicfeatures. We perform partially jointestimation of four features: the VTLN warpingfactor, the corner position of the piece-wise linearwarping function, spectral tilt in voicedsegments, and model variance scaling. In experimentson the Swedish PF-Star children database,joint estimation of warping factor andvariance scaling lowers the recognition errorrate compared to warping factor alone.

Presenting in English or Swedish: Differences in speaking rate
- 2008
-
Ingår i: Proceedings of Fonetik 2008. - Gothenburg: Gothenburg University Department of Linguistics. - 9789197719605 ; , s. 21-24
-
Konferensbidrag (refereegranskat)abstract
- This paper attempts to quantify differences in speaking rates in first and second languages, in the context of the growth of English as a lingua franca, where more L2 speakers than ever be-fore are using English to perform tasks in their working environments. One such task is the oral presentation. The subjects in this study were fourteen fluent English second language speakers who held the same oral presentation twice, once in English and once in their native Swedish. The temporal variables of phrase length (mean length of runs in syllables) and speaking rate in syllables per second were cal-culated for each language. Speaking rate was found to be 23% slower when using the second language, and phrase length was found to be 24% shorter.

(Re)use of place features in voiced stop systems: : Role of phonetic constraints
- 2008
-
Ingår i: Proceedings FONETIK 2008. - University of Gothenburg. - 9789197719605
-
Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Computational experiments focused on place of articulation in voiced stops were designed togenerate ‘optimal’ inventories of CV syllables from a larger set of ‘possible CV:s’ in the presenceof independently and numerically defined articulatory, perceptual and developmentalconstraints. Across vowel contexts the most salient places were retroflex, palatal and uvular.This was evident from acoustic measurements and perceptual data. Simulation results usingthe criterion of perceptual contrast alone failed to produce systems with the typologically widelyattested set [b] [d] [g], whereas using articulatory cost as the sole criterion produced inventoriesin which bilabial, dental/alveolar and velar onsets formed the core. Neither perceptualcontrast, nor articulatory cost, (nor the two combined), produced a consistent re-use ofplace features (‘phonemic coding’). Only systems constrained by ‘target learning’ exhibiteda strong recombination of place features.

On the Non-uniqueness of Acoustic-to-Articulatory Mapping
- 2008

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper studies the hypothesis that the acoustic-to-articulatory mapping is non unique, statistically. The distributions of the acoustic and articulatory spaces are obtained by minimizing the BIC while fitting the data into a GMM using the EM algorithm. The kurtosisis used to measure the non-Gaussianity of the distributions and the Bhattacharya distance is used to find the difference between distributions of the acoustic vectors producing non unique articulator configurations. It is found that stop consonants and alveolar fricatives are generally not only non-linear but also non unique,while dental fricatives are found to be highly non-linear but fairly unique.

Improving speaker skill in a resynthesis experiment
- 2008
-
Ingår i: Proceedings Fonetik 2008, The XXIst Swedish Phonetics Conference, Juni 2008. - Dept of Linguistics, University of Gothenburg. - 9789197719605 ; , s. 69-72

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- A synthesis experiment was conducted based on data from ratings of speaker skill and acoustic measurements in samples of political speech. Features assumed to be important for “being a good speaker” were manipulated in the sample of the lowest rated speaker. Increased F0 dynamics gave the greatest positive effects, but elimination of disfluencies and hesitation pauses, and increased speech rate also played a role for the impression of improved speaker skill.

Konferensbidrag (refereegranskat)abstract
- The present perceptual investigation pursues the question wether the evaluation of a child's voice as hoarse, breathy or hyperfunctional can be correlated to the degree of non-periodical sections in the signal based on the lack of regular oscillations of the vocal folds. The results show that this is not the case: children with clearly hoarse voices produce a stable and measurable fundamental frequency. In addition, children who show a tendency toward unstable fundamental frequency are not evaluated as hoarse, neither breathy nor hyperfunctional.
