InterSpeech 2015 was the 16th Conference in the annual series of Interspeech events. Speech is the most important biosignal humans can produce and perceive. Still, not all characteristics of speech are fully understood. INTERSPEECH 2015 was therefore organized around the topic Speech beyond Speech: Towards a Better Understanding of the Most Important Biosignal. The event was staged in the recently built Maritim International Congress Center (ICD) in Dresden, the capital of Saxony.
