Bio Sketch was founded in 2005 as an agency for forensic phonetics and has been working continuously and full time since then.

In 2003 I became Full Member of the International Association for Forensic Phonetics and Acoustics (IAFPA)

Voice Comparison has defined a concept for an automatic speaker recognition system originally customized to my needs for voice comparison work in Germany. With the British company Oxford Wave Research a system was co-developed and programmed which has become known as VOCALISE. Today, Vocalise is under the care of Oxford Wave Research and is among the systems that are internationally known in the field of forensic speech science. It is developed further in PARTNERSHIPS with universities and police units. Vocalise is used if the recording characteristics are suitable for automatic analyses and it is used in combination with the classical auditory and acoustic components of a forensic report.

Before beginning my career as an expert witness I earned a Master´s degree which qualified me to work as a speech-language pathologist (speech and voice disorders in adults) in a supervisory position as well as a lecturer at a university of applied sciences.

I earned the qualification to teach German as a Second Language. In the language teaching activities that I have conducted over several years I have gained experience in second language acquisition patterns and processes based on the various foreign languages that are spoken in Germany today.

During my student years I acquired experience in working with acoustic phonetics internationally e.g. in the United States and England. Here I also learned most of the auditory skills necessary for analyses and transcriptions of the sounds of the world´s languages.

A second graduate (post-graduate) program in Phonetics led to the completion of my doctoral thesis on vocal stress parameters in language and voice among police officers. I was supported by the German Bundeskriminalamt, the Hessian Police University of Applied Sciences as well as the German GSG9 Special (SWAT) Unit.

I was able to publish in peer reviewed journals and hold seminars on forensics. International relations and research grants enabled me to work, live, and do research in several countries.
