SLT-Code: A new hackathon to promote language diversity in speech technology

Two-day hackathon will provide a hands-on approach to building speech-technology applications for underrepresented languages; registration deadline is Sept. 30.

Nowadays, speech technology permeates our everyday life. From smart-home devices to in-car navigation systems to chatting with friends on the other side of the planet, countless speech applications inform our worlds and enable us to do things that were unthinkable only a few years ago and that we now take for granted.

However, in thinking about how this technology has changed the lives of so many, it’s worth recalling the famous quote from science fiction writer William Gibson: “The future is already here — it’s just not very evenly distributed.”

This two-day speech technology hackathon will focus on language diversity, with the goal of developing a diverse community of speech technology practitioners and researchers.

While a native English speaker can enjoy a wide set of technologies with state-of-the-art performances, the same might not be true for a Balinese or a Gulf Arabic speaker. We want to help change that.

The Spoken Language Technology Workshop (SLT) is the biannual flagship event of the IEEE Speech and Language Processing Technical Committee. As such, SLT brings together researchers from both academia and industry to present their work and learn about state-of-the-art technologies in fields such as automatic speech recognition, text-to-speech, spoken dialogue systems, and speech-to-speech translation.

Next year’s event will be significant, as it will be the first time a speech technology conference takes place in the Middle East and in an Arabic-speaking nation. In celebration of these milestones, the theme of this year’s event is “Languages of the world”.

The Spoken Language Technology (SLT) workshop will be held in Doha, Qatar, in January 2023, the first time that a speech conference will occur in the Middle East.

Moreover, for the first time in the history of SLT, we are organizing SLT-Code, a two-day speech technology hackathon. Following the main workshop’s theme, the hackathon will focus on language diversity. Our goal: develop a diverse community of speech-technology practitioners and researchers, specifically targeting the inclusion of researchers from underrepresented regions and low-resource languages.

This year's areas of interest for the hackathon include (but are not limited to)

  • Low-resource languages, e.g., African, Indian, or Asian languages
  • Language identification
  • Automatic speech recognition
  • Machine translation
  • Text to speech 
  • Speech-to-speech translation

While participants will be free to use any technology of their preference, the organizers will support the following frameworks:

  • Lex/Alexa
  • Huggingface
  • Speechbrain
  • ESPNet
  • K2/Kaldi

We are looking forward to welcoming participants from different backgrounds and are eager to read about your speech technology ideas. To participate, please register by September 30, 2022.

Important dates

  • September 30, 2022: Call for applications and submission of idea proposals
  • October 12, 2022: Idea selection and invitation to participate
  • October 12 – November 1, 2022: Team-forming phase, mentor assignment
  • January 7 – 8, 2023: SLT-Code
