Fundamental Frequency in the Viennese Dialect and Standard Austrian German under different conditions
Sylvia Moosmüller, Austrian Academy of Sciences, Acoustics Research Institute
The influence of various factors on the production of the fundamental frequency has been well addressed. The difference between languages and/or language varieties is also well documented.
The current research interest is inspired by the following reflections:
- Analysis of the fundamental frequency in Austrian varieties is still under researched. No mean f0 and f0 variability data exists for certain sections of the population.
- Situational factors affecting incriminated data and reference material of the suspects have been investigated and compared. However, on the psychological level, taking reference material from a suspect's voice differs from recording speech material from volunteers. Therefore, it can be expected that the mean fundamental frequency differs between these groups insofar as f0 tends to be higher under the first condition.
Method: Speech material for 8 male Viennese Dialect speakers and 8 male speakers of the Austrian Standard will be analysed. Of each group, 4 have been suspects in a forensic case, whilst the other 4 have been volunteers in a project on Austrian German. From each person, read text and spontaneous speech will be analysed. The fundamental frequency will be calculated by SIFT using the acoustic workstation STx developed at the Acoustics Research Institute of the Austrian Academy of Sciences. Mean and variability coefficients will be calculated and statistically compared.
