Speech Processing and Machine Learning

 

Professor Hermann Ney, Chair of Computer Science 6 at RWTH Aachen

 

The Lecture

No innovation has changed human life more than the development of language and the invention of writing. Spoken and written language form the most important foundation for both human communication and the transfer and storage of knowledge and information, particularly in the globally networked and multilingual digital world of today.

Speech and its processing are considered typical human abilities. The development of automatic systems for speech processing is viewed as a core task in so-called artificial intelligence with the rise of the computer. Typical tasks of speech processing include the recognition and comprehension of spoken language and translation between different languages. The most successful concepts in automatic speech processing until now assume that the computer learns using sample data and works with plausibility evaluations instead of prescribed categorical rules. This occurs with processes from statistical decision theory and machine learning, which also includes artificial neural networks.

Using historical developments, the lecture presented different approaches to automatic speech processing and the current state of science
