Nobody can know everything about spoken language processing. Whatever aspect of the field we work in, we have to get help from experts in other fields. For example, for my work on the phonetic structures of dying languages, I rely on the talents of linguists, anthropologists, sound recording engineers, physiologists, psychologists and signal processing engineers to support my own phonetic knowledge. We are fortunate in that by coming to a congress such as this we can all profit and get a little help from our friends.
