LAT service to be discontinued in November 2020


For technical reasons, the LAT service ( will be discontinued in the Language Bank of Finland as of November 30, 2020.

The LAT platform itself is no longer developed in its present form by MPI, and the media browser component Annex (part of LAT) is based on deprecated Adobe Flash technology that will stop working at the end of this year.

What will happen to the corpora that used to be available in LAT?

A replacement service for LAT has not yet been selected by the Language Bank of Finland. However, all the speech and sign language corpora that were previously available in LAT will be made available by alternative means.

All of the LAT corpora can be offered as downloadable packages that can be used and studied directly on the user’s local computer. In the download service, the corpora can be accessed under the same conditions as via LAT. For some corpora, more advanced solutions might already be available.

Which corpora are affected by LAT shutting down?

The LAT instances of the following corpora will be affected:

  • aku-egg: Speech and EGG (Electroglottography) Simultaneous Recordings
  • cfinsl-conv: Corpus of Finnish Sign Language: conversations
  • cfinsl-elicit: Corpus of Finnish Sign Language: elicited narratives

  • elfa-lat: The Helsinki LAT Version of the ELFA Corpus

In order to see where each corpus will be located in the future, please refer to the corresponding metadata page where this information will be updated. The relevant metadata links are provided on the list above.

I came to this page via a PID, how do I know where the file is?

LAT assigned 25000 PIDs to individual files. We have no automatic mapping of these PIDs but we can help you find the file if you need it. We aimed to structure downloadable packages similar to the dataset structure on LAT. To locate a file look into the URL field of this page where you find a ”?path=...” parameter. Example: ?path=demo/TRASH/2017-01/526/v7556__.C_4.4_Viittomakielisten_kielelliset_oikeudet.imdi

This should help you locate your file, please contact us if you have any questions.


August-September 2020:

  • The (numerous) persistent identifiers assigned by LAT to individual files will be redirected to stopover/tombstone pages. There will be one tombstone page per dataset.
  • The LAT corpora that are not yet offered in Download will be moved there and their persistent identifiers will be updated to point to their new home.
  • Assuming that too many errors are not detected, this process should be complete by October.

September-October 2020:

  • Decisions are to be taken as to what kind of streaming services the Language Bank can implement for audio and video materials in the year 2021.

30th November 2020:

  • The support for the server where LAT is located will be discontinued and the service will be shut down.
  • All the corpora that were previously offered via LAT will continue to be offered at least for download.

Year 2021 (and later):

  • Given that there are sufficient resources, more functionalities for browsing, searching, and analyzing speech and sign language corpora can be added.

Further details on the schedule of the aforementioned process will be updated on this page. In case you need additional information at this point, please contact FIN-CLARIN directly.
