Metadata descriptions and other interoperability standards : Deliverable D4.1
- 2011
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- An important aim of META-NORD is to upgrade and harmonize national language resources and tools in order to make them interoperable, within languages and across languages, with respect to their data formats and as far as possible also as regards their content. Since resources and to some extent tools will remain in one location – one of a number of META-NORD centers – the preferred way of accessing and utilizing resources and tools will be through metadata and APIs, allowing the assembly of on-the-fly tool-chains made up of standardized component language technology tools, processing distributed – and in many cases interlinked – language resources in standardized formats.

Neural processing of voices - familiarity
- 2013

Konferensbidrag (refereegranskat)abstract
- Brain responses to familiar and unfamiliar voices were investigated with ERPs (Event Related Potentials). Presentation of a stream of one syllable utterances from a female voice established a standard expectation, and similar samples from four other male voices where inserted as unexpected deviants in a typical mismatch paradigm. The participants were 12 students from the basic course in linguistics. Two of the deviant voices were familiar voices of their teachers. The two other deviant voices were matched (same age, sex and dialect) but unfamiliar to the participants. A typical MMN (Mismatch Negativity) was elicited, i.e. a more negative response to the deviants compared to the standards. In contrast to verbal reports, where only one participant identified any of the deviant voices, the MMN response differed on group level between familiar and unfamiliar voices. MMN to familiar voices was larger. Using teachers' voices ensured naturalistic long term exposure, but did not allow for random assignment to conditions of familiarity making the design quasi-experimental. Thus acoustic analysis of voice characteristics as well as follow up studies with randomized exposure to voices are needed to rule out possible confounds and establish a causal effect of voice familiarity.

Effects of initial sounds on the perception of Chinese disyllable tones by Swedish students of Chinese
- 2014

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- ABSTRACT This paper extends previous research on the effects of initial sounds on perception of Chinese disyllable tones. A perception test was performed on Swedish adult students of Chinese using disyllable words (most previous studies have been made using solely monosyllable words). The main results indicate that voiced initial sounds e.g. [l] have a strong connection to the tone confusion pattern Tone 2 perceived as Tone 3. On the contrary, a voiceless aspirated initial sound e.g. [th] is mostly connected to misidentifications between Tone 3 to Tone 2. Unvoiced unaspirated initial sounds affect tone perception heavily, especially when they occur in the second syllable of a disyllabic word.

PERCEPTUAL MISTAKES OF CHINESE TONES IN 2-SYLLABLE WORDS BY SWEDISH LISTENERS
- 2010
-
Ingår i: Proceedings of the Fourth European Conference on Tone and Intonation (TIE4).
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Earlier studies on the perception of Chinese tones have almost exclusively used 1-syllable words for the listening tests (Kiriloff, 1969; Chuang, 1971; Klatt, 1973; Gandour, 1978). In these earlier studies the misperception between tone 2 and tone 3 has been shown to be the most common. However, no studies that we have found have looked at the perception of 2- syllable words besides Chuang (1971), who only used nonsense words. By tradition the teaching of Chinese as a foreign language has been concentrated on training of perception and production of tones since adult students have been shown to show particular difficulties in perceiving their difference. Experienced teachers have through tests established that this assumption is not valid when it comes to the so-called static tone. When it comes to communicating in Chinese and to be able to use the separate tones it is not enough to know the difference in 1-syllable words especially since most modern words in standard Chinese contains 2 or more. Guo (1993) has shown that the more syllables a word contains the higher ratio of misperceived tones. So far, no investigations for Swedish students have been performed. A possible hypothesis could be that Swedish listeners would perform better due to the Swedish grave and acute accents. By asking experienced teachers in Sweden, we knew that this should not be the case however. The general impressions from teachers are also that Swedish students have the largest proportion misperceptions between tone 2 and 3. To test this we conducted a listening test on 27 native speakers of Swedish (9 bilingual Chinese speakers with native ability in Swedish) on 25 Chinese 2-syllable lexical words with 15 different tone combinations. One male and one female native speaker of Chinese pronounced the words in isolation. The words were taken from a random number of 2-syllable glossary. Each speaker repeated the words once with 1 seconds pause in between the repetition and then 2 seconds pause before the new word. The audio was presented in high quality headphones in the student language lab at the University of Gothenburg. The participants were all second semester students of Chinese and the listening test was also an exam, which made the participants wanting to perform as well as possible. If they wanted they could repeat the sequence as many times as they until satisfied with their answer. The results show that produced tone 1 and tone 2 are confused more than 3 and 4 (tone 4 more than 3, see figure 1). However, the distribution of misperceptions seems to be rather equally distributed if we exclude the static tone (below called 0) in contradiction to earlier studies claiming misperception mostly between tone 2 and 3. However, we also notice that certain types of syllables containing different vowels are misperceived differently. The next step is to figure out if certain syllable nucleuses are more misperceived than others and in certain positions. These conclusions can in the future lead to new approaches when it comes to teaching students production and perception of tones.

operAVoX - On PErson RApid VOice eXaminer : High-Quality Voice Analysis Made Easy with OperaVOX™ - the “On PErson RApid VOice eXaminer”
- 2012

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- At present, objective analysis of voice quality using acoustic parameters is only possible within a voice laboratory using specialist hardware and software. We have developed an easy-to-use portable voice analysis and feedback application running on the Apple iPhone, iPad, or iPod Touch. OperaVOX™ combines the signal processing power, easy connectivity, user-friendly interface, high-quality microphones and portability of these handheld devices with novel acoustic voice analysis algorithms to provide a powerful voice quality measurement tool that you can carry in your pocket. OperaVOX™ is designed for anyone who is interested in measuring the quality of their voice, such as a patient recovering following a stroke, a professional voice user such as singers or an aspiring actor. Built into OperaVOX™ are the validated Voice Handicap Index questionnaires and the ability for the user to record their voice for acoustic and perceptual analysis both on board the device and externally in the voice laboratory. Furthermore, the user can instruct OperaVOX™ to automatically and confidentially send these data via email to their speech therapist, voice coach or researcher team. OperaVOX™ makes it easy for everyone to accurately measure changes in the quality of their voice every hour, day, or week and without having to travel to the hospital. Two versions of OperaVOX™ will soon be available on the Apple App Store, one for the general public and another for professionals such as speech and language therapists. We have also worked with world-leading University research teams both in the UK and North America to develop bespoke versions of OperaVOX™ specifically tailored for their research and clinical requirements.
