First milestone in the Language Technology for Icelandic project

The LVL team celebrating the first milestone in the Language Technology for Icelandic project. Ólafur Helgi Jónsson, Sunneva Þorsteinsdóttir and Steinþór Steingrímsson are missing from the picture.

Last week we celebrated achieving the first milestone in the Language Technology for Icelandic project with a cake!

After a lot of hard work the past few months we achieved the first milestone in Automatic Speech Recognition (ASR), Text-to-Speech (TTS) and Machine Translation (MT).

In ASR, the focus has mostly been on data creating and gathering. 55,000 utterances have been collected (donated by adults) via the crowd-sourcing platform (based on Common Voice) with plans to reach 100.000 utterances for the next milestone. The process is being extended to include younger voices in collaboration with schools and authorities. Today we started working with Öldutúnsskóli in Hafnarfjörður. The goal is to reach 80.000 young voice utterances for the next mileston. Additionally, data has been gathered from RÚV (audio, video and subtitles) and CreditInfo (transcriptions). Along with data gathering, the team is also developing tools to post-process Icelandic ASR text for better readability.

In TTS, we successfully created a voice recording client (LOBE) and three reading scripts in order to collect high quality speech and corresponding text data. The reading scripts were created from Risamálheild and seek to maximize diphone coverage. So far 20 hours have been collected from two speakers, male and female. The aim is to finish collecting 20 hours from each speaker early this year. From the collected data two TTS prototypes have been created in Ossian, which extends the Merlin back-end. The current prototypes are quite naive but we have integrated a grapheme-to-phoneme model for the Icelandic language into the prototypes.

In MT, we successfully created a phrase-based statistical machine translation system using the open source tool Moses. Our collaborators at Miðeind created neural machine translation systems based on BiLSTMs and Transformers. The models were trained on the newly available English-Icelandic parallel corpus, ParIce. The systems were then evaluated w.r.t. training time, throughput and BLEU score. The code and 
systems are freely available but are still under development for milestone two. In milestone two we will continue to develop the systems further and adjust them to specific needs of the Icelandic language.

Donate your voice to bring Icelandic and technology together!

Hello everyone!

We are collecting audio clips to create a new, more robust Icelandic dataset. We plan to use them for automatic speech recognition and text-to-speech applications. This could lead to many applications that you can use in your everyday life, like an Icelandic voice assistant, screenreaders, and searchable audio and video content. The dataset will soon be available directly on the Samromur website for users and developers alike to download and use to creating exciting new technology. But to do this, we need your voices, Icelandic speakers.

You can get started by going to  and choosing Tala. You only need to donate 5 recordings per session, but more is always welcome. If you want to do more, you can also evaluate clips made by other users with Hlusta.



We are also organizing data gathering competitions within companies. So, please contact us if you and your company would be interested in holding a competition.

This is a joint effort with Deloitte and Almannaromur. If you want to learn more about this project, visit the Um Verkefnið tab on the Samromur site.

Can stress be measured?

For the past few years, Eydís has been looking into it. She did a cross analysis on different measurements of cognitive workload with respect to the Icelandic flight industry. Cognitive workload, for the purposes of this article is synonymous with stress. The research indicates there are clear differences in measurements when an individual is rested or stressed. While the research focused on individuals in the aviation industry, the results can be applied to all people.

So, the answer to “Can stressed be measured?” is yes, most definitively. To get a more in-depth explanation of the indicators of stress, please read Eydís’ PhD thesis here

For more on the topic, read it here in Icelandic:

This research has been done in collaboration with ISAVIA and Icelandair.

Eydís has successfully defended her PhD thesis!

Eydís and the LVL members at her celebration.


We are pleased to announce that Eydís has successfully defended her PhD thesis on “Cognitive workload classification with psychophysiological signals for monitoring in safety critical situations” on 18th of January. Over the past few years, Eydís has worked on a dissertation studying the effect an increased cognitive workload has on acoustic and cardiovascular signals. She collected data from over 100 participants in a simulated environment, which she analyzed quantitatively and qualitatively. The key contribution of her thesis is in using a signal processing approach and showing that an involuntary response of the cardiovascular system can very accurately reflect one’s mental effort during a task. The thesis is a result of her cooperation with Isavia, and their effort to improve management of people working in an air traffic control environment.

Congratulations Eydís!

SLT 2018 here we come!

This year we’re branching out and attending a smaller conference, IEEE SLT 2018!

We will be presenting the results from our paper, “An Icelandic Pronunciation Dictionary for TTS.” The work was done in collaboration with the linguist and Icelandic specialist, Eiríkur Rögnvaldsson from the University of Iceland.

The paper describes an Icelandic pronunciation dictionary for use in a text-to- speech system for Icelandic. Procedures were implemented to create a consistent training set for grapheme-to-phoneme (g2p) conversion modeling, needed for automatic extensions of the dictionary. The experiments show a clear benefit of using clean data for training, both in terms of PER and in terms of categories of errors made by the g2p algorithm. The results of the dictionary processing were also used to create an initial version of an open source database for Icelandic speech applications. The scripts used in the experiments are available via our Github repository:

Jón and Anna Björk’s poster presentation will be at SLT on Friday, Dec. 21 between 10:00 and 12:00 PM. Here’s a sneak peek.

We hope to see you there. If you see Anna or Jón please stop by and say hello.
