Dr. Johannes Twiefel

Hello,

I am Johannes, a passionate AI engineer and speech recognition expert. In 2007, I started with Java programming, switching over to Python in 2013, which from then on I used for my daily programming tasks.

From 2014 until 2021 I was a researcher at the University of Hamburg, finished my PhD (Dr. rer nat.) in the field of automatic speech recognition and natural language processing in 2020 publishing 22 scientific papers, all representing different topics and programming challenges.

I am an expert in the field of speech recognition, natural language processing, machine learning, deep learning and other neural networks, also traditional AI and robotics. From 2014 to 2018, I was giving courses at the University of Hamburg in Data Mining, Human-Robot Interaction, and Fundamentals of Knowledge Processing and supervised several Bachelor's and Master's theses. My research focussed on applied speech recognition, making it practical research that can be used in industry.

My daily tasks contained mainly developing and programming new AI algorithms, implementing automated experiments on benchmark datasets, evaluating, interpreting and visualizing the experiments' data and reporting the performance of the newly developed algorithms in scientific publications.

In 2020, I started with founding a startup (exXxa GmbH) in the area of applied speech recognition, receiving a funding of ~150.000€ from the Federal Ministry for Economic Affairs and Climate Action (Bundesministerium für Wirtschaft und Klimaschutz). exXxa achieves the best recognition accuracy for German speech recognition among all competitors. The experiments were performed on a public German benchmark dataset and can be reproduced by everyone.

I am happy to find new challenges here.

Looking forward to your projects!
