VOICE Online

VOICE Online is available as a free-of-charge resource for non-commercial research purposes. VOICE 1.0 Online was published in May 2009 and is now being used by registered users all around the globe. A revised version was released on 5 May 2011. As of January 2013, registered users will be accessing VOICE 2.0 Online, a further updated version of the corpus that includes minor revisions in some of the corpus texts.

The Vienna-Oxford International Corpus of English (VOICE) was created by Barbara Seidlhofer (project director) and Angelika Breiteneder, Theresa Klimpfinger, Stefan Majewski, Marie-Luise Pitzl (project researchers) at the University of Vienna in a time-, labour- and cost-intensive process. Revisions and corrections were made by Ruth Osimk. We are making VOICE available to be used for non-commercial research purposes. It is in this spirit that access to VOICE Online is provided free of charge to all those who are interested in using the corpus for such purposes.

VOICE Online breaks new ground in that it is the first corpus of English as lingua franca (ELF) to become publicly available. We have taken great care in the compilation of our (just over) 1-million-words corpus to meet the qualitative and technical standards of state-of-the-art corpus linguistics in data collection, transcription and encoding.

VOICE Online is released with a considerable amount of corpus documentation (see Corpus information and Corpus statistics). Similarly, the corpus itself contains a substantial amount of meta-information on speech events and speakers in the corpus header as well as in individual text headers. We strongly encourage all users of VOICE to take note of this documentation and the meta-information when working with the corpus. In addition, as of November 2010, 23 recordings of transcribed speech events can also be listened to. We expect researchers to handle the data provided in a responsible way and in accordance with generally accepted ethical and scientific principles at all times.

We would like to encourage you to let us know when you publish or present work based on VOICE Online. Please send us a message at
