My research focuses around three topics: bias in speech perception, Chinese linguistics, and the interaction between frequency effects and grammar (with a current focus on language acquisition). The languages I currently investigate are mainly French, German and Chinese languages, but I investigate other languages as well (like Dutch, Japanese). I co-operate on a long term basis with Prof. Liang Jie (Tongji University) and Prof. Jeroen van de Weijer (Shanghai International Studies University).

Paving the Way for a More Reliable Linguistics
Speech transcriptions, the decoding of sounds in letters or other visual symbols, are important means for investigating pronunciation. For instance, sounds of a particular dialect can only be statistically analysed if they have been transcribed. Transcriptions are also used in foreign language education, speech therapy, and language counselling (like in asylum requests). Transcriptions are currently often made by speech processing software, but have to be corrected manually: it cannot fully replace human codings. Some sounds cannot be analysed by speech processing software at all. But are human codings reliable? The answer is probably no. Recently, it turned out that linguistically subjects are easily biased towards an overall accent they perceive in a speaker, such that coders exposed to a certain accent may expect and therefore actually hear prototypical characteristics of this accent—even if these are not present in the phonetic signal. Even professional coders turned out to be subject to coder bias. The scope of this deviation in formal transcription tasks is still unknown, neither has a standard procedure been developed in order to arrive at better results. Since human codings should be as accurate and as reliable as possible, this research aims at the development of a “gold standard” for linguistic transcriptions.
Bane Vejen for en Mere Pålidelig Lingvistik (Dansk)Projektbeskrivelse: Transskriptioner af tale er vigtige redskaber i udtaleforskningen. For eksempel kan lydene i en bestemt dialekt kun analyseres statistisk, hvis de er blevet transskriberede. Transskriptioner bruges også indenfor fremmedsprogsundervisning, taleterapi og sprogrådgivning (som for eksempel i asylansøgninger). Transskriptioner laves i dag ofte med digitale talebehandlingsprogrammer, men de skal rettes manuelt, da software ikke fuldt ud kan erstatte menneskelige kodninger. Nogle lyde kan slet ikke analyseres ved hjælp af digitale talebehandlingsprogrammer. Men er menneskelige kodninger pålidelige? Svaret er sandsynligvis nej. Nyere undersøgelser har vist, at de fonetiske træk, som man hører, let påvirkes af en talendes accent. Det betyder, at den lyttendes forventninger påvirker de prototypiske særpræg, som han eller hun hører ved en accent, selv når disse særpræg ikke er til stede i det fonetiske signal. Selv professionelle transskribenter har vist sig at ligge under for egne forventninger. Mængden af afvigelser i formelle transskriptionsopgaver er stadig ukendt, og der er endnu ikke udviklet en standardprocedure for at opnå mere konsistente resultater. Formålet med denne forskning er at bidrage til udviklingen af standardiserede transskriptionskonventioner, der kan fungere som retningslinjer i sprogvidenskaben. Da menneskelige kodninger bør være så præcise og pålidelige som muligt, sigter denne forskning mod at udvikle en gylden standard for sproglige transskriptioner.
Together with Liang Jie and Wang Lei (Tongji University), I investigate the Luoyang dialect, a Mandarin dialect of the city and surroundings of Luoyang. Luoyang is regarded as the craddle of Chinese culture and pholiosophy--the great sage Lao Tze was born here. The dialect of Luoyang has been previously described in Chinese and we are now reinvestigating the data and make the knowledge about this (presumably archaic) dialect available in English. We concentrate on the sounds of Luoyang, the tone system, and syllable contraction.
Further, we are investigating interaction of tone and intonation in Chinese dialects.
Frequency effects and grammar
My PhD focused on the interaction between frequency effects and phonological grammar. For my PhD, I investigated variation and change in German, Indonesian, and Japanese. This work is continued, now involving language acquisition in different languages as well (with Jeroen van de Weijer). In search for the optimal representation of the relation between the lexicon and the grammar, I work within the generative framework of phonology as well as usage-based phonology.
My earlier research was mainly concentrated on different aspects of Dutch and German: (Loanword) phonology, phonological microvariation and sociolinguistics. I investigated umlaut in Dutch dialects, the pronunciation of the BÄREN vowel in Standard German, reduction in Dutch, loanwords in Dutch and Dutch loanwords in Indonesian. More publications about these topics are underway.
