Speech technology

Over the next two years, we will travel throughout Denmark and record the dialects and accents of more than 2,000 Danes. This will result in a data set of almost 1500 hours of Danish voice data, which will be freely available to everyone. We do this to support Danish authorities and companies in developing even better Danish speech technology.

The coral project

Expansion of Speech Technology

Innovation Fund Denmark has granted 14 million Dkr for a project that aims to bring Danish speech technology up to international level. Over the next two years, we will develop a speech dataset called CoRal, which is an abbreviation for Danish Conversational and read-aloud speech dataset.

The data set will contain 1000-1500 hours of conversation and read speech from a broad and representative section of the population with regard to gender, age, Danish dialects and foreign accents. At the same time, we will develop language models that are able to recognize Danish speech and read Danish text aloud.

All data and models will be tested and published regularly, so that developers, companies and public institutions can benefit from them right from the start.

The benefits of speech technology

Speech technology can help understand and reproduce spoken language and to support:

  • Speech recognition tools for elderly people, citizens with visual impairment or special needs
  • Medical dictation or automatic documentation of conversations with citizens or customers
  • Voice and chatbots for IT support for resetting passwords, website navigation etc.
  • Better machine translation between Danish and other languages
  • Better voice navigation for example for GPS or in public transport
  • Decision support with relevant knowledge for the employees
