Opening for a PhD position

Update: the position is filled.

The Laboratory of Phonetics and Speech Technology seeks qualified candidates for one PhD student position in the field of automatic speech recognition. The preemptive title of the thesis is Adaptive Deep Neural Networks for Speech Recognition and Keyword Search.

We offer a fulltime post for a period of two to a maximum of four years. Salary will depend on education and experience.

Topic description

Speech recognition models are known to be fragile against mismatches in training and testing conditions. The mismatches can be caused by the environment and channel or the physical and social characteristics of the speaker. Although DNNs improve speech recognition performance in both clean and noisy conditions, processing data that is to some extent distinct from training data is still a major research problem. This thesis investigates adapting DNN models for speech recognition to conditions different from the training data, using little or no additional human-transcribed speech data. We will seek methods that can be applied in an online fashion, without requiring long-running steps to retrain the existing models. The focus is on developing DNN models that are adaptive to the input signal, i.e., that adapt to the varying and changing speech conditions automatically. The methods developed during the thesis will be applied for speech recognition and keyword search. The experiments concentrate on speech data that has been previously been difficult to process, such as interviews made with a far standing microphone, recordings from historical multimedia archives.
