Alvenir's mission is to help companies leverage the promises of AI to drive efficiency, customer satisfaction and decision-making while simultaneously keeping the human touch.


Alvenir traces its roots back to the Technical University of Denmark (DTU) from which the company is a spin-out. While at DTU the founding team spent the better part of three years researching ways to improve natural language processing capabilities in data scarce settings. 


Funded by Innovation Fund Denmark the work at DTU led to several contributions including scientific publications, public talks and most importantly the first open-sourcing of an automatic speech recognition model for Danish.


Alvenir spun out from DTU in December 2021 and has since then continued to play an important role in the open-source community, staying true to its initial commitment, while continuing to expand its proprietary services and offerings.


Today Alvenir operates in the financial industry, with its primary business focused on creating and operating specialized AI models to augment and enhance financial advisors in their interactions with customers.

The startup Alvenir has built a scalable platform for speech recognition based on research from DTU. A platform that already speaks better Danish than Google and Amazon. The goal is a big business, yet the language models behind it are made available to others for free through open source.

#36 Alvenir - Specialiseret dansk NLP

I denne episode kommer Martin Carsten Nielsen fra den danske start-up Alvenir i studiet. Alvenir er sprunget ud af et speciale på DTU, hvor de to studerende efter et års tid, slog sig sammen med den vejledende professor, og i dag angriber Fin-tech markedet, med specialiseret NLP. I stedet for at udvikle store generelle danske modeller, tilpasser de nemlig de eksisterende og udvikler dem, til Fin-tech. Vi taler også om Alvenir som platform og demokratisering af data.

How data-centric machine-learning can enable new business cases Alvenir

This lunch talk focused on real-life applications of speech and voice recognition in the financial sector. Focused on how to capture value with a variety of workflow applications and dived a little deeper into the hidden caveats of off-the-shelf speech-and-voice solutions before ending with a discussion on how specialization of the underlying machine-learning models can help overcome some of the most common issues.

Godaw’ do: Nu skal danske dialekter samles i en digital bank

Projektet skal sikre, at stemmestyret teknologi kan forstå de mange danske dialekter. Indsamlingen af dialekter kommer rundt i hele landet, og bliver skudt i gang i dag i Nordjylland. På sigt skal de mange timers tale blandt andet hjælpe medarbejdere på alarmcentralen med at forudse hjertestop.
