Research

Main research interests: Artificial Intelligence (AI), multilingual and multimodal human-machine interaction technologies, Time Delay Neural Network (TDNN)

Alexander Waibel is a Computer Scientist, well known for his work on Artificial Intelligence (AI), multilingual and multimodal human-machine interaction technologies. His scientific work was driven by the early conviction that intelligent systems must learn, and that complex language technologies must rely on machine learning and interaction.

This lead to early learning systems applied to speech and language. Waibel’s pioneering work on the Time-Delay Neural Network (TDNN, 1987) showed for the first time that neural networks could be learned shift- invariantly. It demonstrated that deep learning of patterns is possible, even when their exact position is not known. This most important property of TDNN’s was first shown in speech recognition and later applied to image classification under the general name “convolutional neural networks”. Extensions are now important building block element in most modern AI systems today.

Building on these and other machine learning advances, Waibel and his team proposed intelligent communication systems that make human communication easier. These included work on speech dictation, dialog systems, machine translation, synthesis, multi-modal interfaces, computer vision, and speech-to-speech translation: Waibel and his team proposed the first speech translation systems in Europe and the US (JANUS, 1991), the first visual road-sign translator (2001), the first translating goggles (2004), the first automatic simultaneous interpretation system of lectures (2005), and the first speech translation mass-market product on a phone (Jibbigo, 2009).

Waibel’s research is also concerned with understanding multiple communication signals in their joint communicative intent. This is central to making human interfaces more natural and effective. The resulting innovations included: computer lipreading (1993), cross-modal error-repair (1994-1998), emotion recognition from speech (1996), focus of attention tracking (1998) and meeting transcription, tracking and browsing (1998). Waibel holds many patents for work in these areas.

His work is also characterized by a passion for fundamental science and transitioning it to public use: Waibel founded and co-founded more than 10 start-up companies, provided technology support for humanitarian crises and healthcare missions, and developed and deployed the first simultaneous interpreting service for University lectures (KIT). He is now also working with the European Parliament on advanced language support.
