A national volunteer effort to give AI a real, human voice
There are few things that say more about who we are than the way we speak. Our dialect reveals where we come from, the words we choose show who we are, and the rhythm of the language tells how we feel.
In encounters with artificial intelligence, all of this disappears. The voice becomes flat. The words lose their tone. AI may understand what you say – but not how you say it.
Therefore, we are launching Threll Voice Lab – an initiative to build the world's best voice AI for the Norwegian language.
A Norwegian language project – with a focus on Scandinavia
The Norwegian language is beautiful – but a nightmare for artificial intelligence. We have two official forms, hundreds of dialects, and significant variations in intonation, speed, and vocabulary. For an AI trained on English, Norwegian sounds like ten different languages at once.
Therefore, we start here – in Norway. We will train artificial intelligence to understand us as we actually speak. Once we master the Norwegian language, the technology will form the basis for expanding to the entire Scandinavian language area.
Our vision is to give artificial intelligence the ability to understand – and speak – Norwegian. Our beginning is to master all the dialects that make Norway unique.
From keyboard to voice
Artificial intelligence has learned to read and write. Now it must learn to speak and listen.
The transition from text-based AI to voice AI is enormous. A voice must interpret meaning through breathing, pauses, background noise, and emotions – not just letters. At Threll Voice Lab, we research and develop the technology that makes this possible:
- Speech recognition (ASR) – that understands what is being said, even when the line is noisy.
- Natural language understanding (NLU) – that interprets what you actually mean.
- Dialog management and model optimization – that makes the conversation natural, human, and intelligent.
- Text-to-speech (TTS) – that gives AI a voice that feels authentic, warm, and close.
Together, this makes up the technological core of Threll.ai's voice agents – Thrells.
