About the Jensson Corpus

The Jensson Corpus is 3.8 hours in length with 5,612 utterances (44.1khz 16 bit) from 20 speakers (13M/7F).

The read text contains words that were chosen with the aim of keeping the text as short as possible even though it contains most of the bi-phonetical utterances that exist in Icelandic. The text is in the form of questions. All the speakers read the same text, about 11 minutes of read text.

CLARIN ERIC

CLARIN ERIC is an ESFRI initiative, one of EU's ERICs – CLARIN stands for “Common Language Resources and Technology Infrastructure” and ERIC stands for “European Research Infrastructure Consortium”. CLARIN ERIC operates according to statutes that have been approved by the European Commission.

The main goal of CLARIN ERIC is that all digital language resources and tools from all over Europe and beyond are accessible through a single sign-on online environment to support researchers in the humanities and social sciences, and for use within language technology.

CLARIN-IS

Iceland joined CLARIN ERIC on February 1st, 2020, after having been an observer since November 2018. The Ministry of Education, Science and Culture assigned The Árni Magnússon Institute for Icelandic Studies the role of leading partner in the Icelandic National Consortium and appointed Professor Emeritus Eiríkur Rögnvaldsson as National Coordinator. Starkaður Barkarson replaced Eiríkur Rögnvaldsson in October 2021. Most of the relevant institutions participate in the CLARIN-IS National Consortium.

During the first years, The Árni Magnússon Institute ran a Metadata Providing Centre (CLARIN C-Centre) but was upgraded in 2023 to a Service Providing Centre (CLARIN B-Centre) which provides both service and access to resources and knowledge.
