• Spoken language ambiguitites

    Dec. 28, 2017, by Bianca Vieru

    Extrapolating from the linguistic ambiguity in the above image, adding some noises, and an assortement of regional and non-native accents, it is easy to imagine the difficulties faced by the automatic recognition systems and all downstream processing technologies that rely on them.

    Speech recognition belongs to the family of technologies that help machines to communicate in meaningful ways with humans and their environment ( According to ComScore, 50% of all searches will be voice searches by 2020   ( It is a basic key component for several trending ...

  • Are you mad at me?

    Dec. 3, 2017, by Oriol Martínez

    To accurately infer the affective state of a subject is a very challenging task even for humans. How many times have you asked to a friend: are you mad at me? and the answer has been different from what you expected.In the KRISTINA project we are teaching an automatic system to performthat task. Isthat possible?

    Machine learning (ML) is a hot topic within Artificial Intelligence (AI) that tries to teach machines using samples instead of explicitly programming them. For instance, if we want to teach a machine to infer if a person is happy or not from its face ...

  • Voice or Noise

    Nov. 6, 2017, by Dominik Schiller

    An important part of many classification systems that are working with a continuous input signal is the fragmentation of this signal into segments that are meaningful to solve the respective task. For any voice related task like speech recognition or emotion analysis from an audio signal for example we would like to identify the segments where the user is actually speaking. In order to do so we need a system that automatically can differentiate a human voice from any other noise that might be present in the signal. Distinguishing between a voice and sounds that originate from other sources is ...

  • KRISTINA goes to the Opera

    July 29, 2017, by Mireia Farrús

    The time of the castrati in the opera, those classical male singing voices equivalent to that of a soprano, mezzo-soprano, or contralto by means of castration is far away. No one could imagine such a technique being carried out nowadays. Luckily enough, it was made illegal in the 19th century, coinciding with the end of the Baroque period and the incorporation of women in the opera.

    At this point, you might be wondering what the relationship between Baroque and KRISTINA is. So well, technologies have evolved so greatly, that we are now able to convert a male voice into a ...

    In Germany, the life expectancy of the people is rising continuously over the years. Because of that the German Federal ...

  • Embrace the Unknown

    July 3, 2017, by Louisa Pragst

    Humans spent years of their life learning the meaning of words and how to respond to them. Even after we learned the basics, we never stop expanding our knowledge, with new, more sophisticated words and sentence structures or even by learning another language. We achieve this by permanently consuming and producing language over an extended period of time. Considering most dialogue systems do not spend years of practising with human conversation partners before they are deployed, how can they obtain the ability to hold a conversation?

    Traditionally, a dialogue system uses a predefined model that specifies everything the user and ...

  • Being KRISTINA: The Question Answering soul that drives the AI mind

    May 29, 2017, by lpmayos

    With the introduction of the first smartphone around ten years ago many people have come to grabs with a new kind of technology that surprised them, as they never thought that their lives would benefit from it as much as they did. The next surprise in this technological journey came five years later, when virtual assistants, a “fairytale” whose origins date back to the 60’s, were introduced in smartphones. It was not just an evolution, it was a breakthrough! Even more so when one considers that these assistants operate from a portable gadget that sits in the palm of ...

  • A better health assistance for migrants: family doctors will help us to evaluate the KRISTINA prototype

    May 12, 2017, by Chiara Baudracco

    Family medicine needs to be supported. Now, more than ever, communication technologies will help family doctors to improve their work especially when necessary to overcome linguistic barriers in order to ensure an effective and accurate assistance. The European Funded Project KRISTINA will develop and present a virtual assistant in the field of healthcare that will enable getting over language barriers when dealing with users and, therefore, its priority application will be to attend migrants who are struggling to overcome linguistic barriers. With the first prototype, KRISTINA becomes a conversation partner and during the last semFYC National Congress it has been ...

  • Standards in Kristina’s Avatar; Meeting between ARIA-VALUSPA and KRISTINA

    March 22, 2017, by lpmayos

    Last month, a workshop between the members of KRISTINA and ARIA-VALUSPA, another H2020 project on interactive virtual agents, was held in Dagstuhl (a computer science centre in the south-west of Germany). During this workshop several meetings to discuss different disciplines that creating interactive virtual agents involves took place.

    From a post of the ARIA-VALUSPA project (by Merijn Bruijnes):
    “The ARIA VALUSPA project (Artificial Retrieval of Information Assistants – Virtual Agents with Linguistic Understanding, Social skills, and Personalised Aspects) aims to create Artificial Retrieval of Information Assistants (ARIAs) that are capable of holding multi-modal social interactions in challenging and unexpected situations. The ...
