6-21 (2017-10-27) Postdoc in ASR and Language Modeling, Aalto University, Finland

Postdoctoral researcher in Speech Recognition and Language Modeling


The speech recognition group (led by Prof. Mikko Kurimo) at Aalto University, Finland, focuses on machine learning in automatic speech recognition (ASR) and language modeling. The group developed a state-of-the-art fixed vocabulary ASR system already in 1970's and an unlimited vocabulary neural phonetic typewriter in 1980's led by Academician Teuvo Kohonen. Since 2000 led by Prof. Mikko Kurimo, the group has developed state-of-the-art unlimited vocabulary ASR systems using sub-word language models for several languages. The most recent achievement is winning the 3rd Multi-Genre Broadcast ASR challenge in 2017, where the top research groups in the field were challenged to build a recognizer for an under-resourced language using machine learning methods.

The speech recognition group consists of a couple of senior researchers, post-docs and six PhD students that bring together expertise from many relevant areas such as acoustic modeling, lexical modeling, language modeling, decoding, machine learning, machine translation, user interfaces, and toolkits such as Kaldi, AaltoASR, TheanoLM, VariKN, and Morfessor. We operate in a well-connected academic environment using excellent GPU and CPU computing facilities and have a functional office space at Aalto University Otaniemi campus that is only 10 minutes away from downtown Helsinki via the new subway line.

We are now looking for a 1-3 year postdoc to start asap on any of our research themes:

  • DNN-based continuous speech recognition (a central theme in many projects)

  • unlimited vocabulary language modelling based on letters and unsupervised morphemes

  • speech recognition for indexing and captioning of broadcast videos in multilingual domain (3-year European project starting in January)

  • speech recognition for games and second language pronunciation training

The position requires a relevant doctoral degree in CS or EE, skills for doing excellent research in an (English-speaking) group, and outstanding research experience in at least one of the research themes mentioned above. More specifically, programming skills and good command of Kaldi and DNNs (either Theano or TensorFlow toolkits) will be useful. The candidate is expected to perform high-quality research and participate in the supervision of the PhD students. The application, CV, list of publications, references and requests for further information should be sent by email to Prof. Mikko Kurimo (mikko.kurimo at

Aalto University is a new university created in 2010 from the merger of the Helsinki University of Technology, Helsinki School of Economics and the University of Art and Design Helsinki. The University?s cornerstones are its strengths in education and research, with 20,000 basic degree and graduate students. In addition to a decent salary, the contract includes occupational health benefits, and Finland has a comprehensive social security system. The Helsinki Metropolitan area forms a world-class information technology hub, attracting leading scientists and researchers in various fields of ICT and related disciplines. Moreover, as the birthplace of Linux, and the home base of Nokia/Alcatel-Lucent/Bell Labs, F-Secure, Rovio, Supercell, Slush (the biggest annual startup event in Europe) and numerous other technologies and innovations, Helsinki is fast becoming one of the leading technology startup hubs in Europe.
