Glossary


Computational audio content analysis

This glossary collects key terms from the field of computational audio content analysis. The aim of this glossary is to provide Finnish translations for key terms in this field to stabilize the terminology. In order to make it usable also for others than finnish researchers, brief English definition is added for each term with links to Wikipedia and Wiktionary. Furthermore, some of the terms have been translated to German, Spanish and French through Wikipedia. The glossary does not try to be complete, as it is work in progress.

Data file used to create this glossary is published as repository:


If you see an error, or you want to contribute make pull request to repository or send me email.
