What ITSlanguage does

ITSLanguage, a product brand of the Netherlands-based d-centralize B.V., is a speech-technology company that builds AI-powered software for speech therapy and language education. Founded in 2012 and headquartered in Eindhoven, the company employs between 1 and 10 people and focuses narrowly on Dutch-language speech recognition, transcription, and phonological analysis. Its product suite comprises KAT (Klank Analyse Tool) for automated phonological analysis of children's speech, Loudly (a therapist-facing testing and assessment platform with ParnasSys integration), ITSTranscription (real-time transcription with editable proposals), the Sound Trainer game-like practice environment co-developed with Royal Auris, TUTO (claimed as the world's first real-time Dutch child-speech pronunciation analyzer with a teacher dashboard), and a developer-facing REST/WebSocket API offering speech-to-text, speaker diarization, alignment, and speech-analysis primitives. The underlying stack combines speech-to-text, speaker diarization, and audio-text alignment with a custom phonological-process detector that, according to the company, reduces manual analysis time from roughly 50 minutes to 15 minutes per case.

The business model is a hybrid SaaS and enterprise-licensing model built around the Dutch speech-therapy and education verticals. KAT is offered freemium to students and educators and via paid licenses to practitioners, with a 4-month free trial extended in mid-2025. Loudly, ITSTranscription, and Sound Trainer are distributed as SaaS web applications, while the API is positioned for developer and enterprise integration with quote-based pricing. Royal Auris Group is the flagship enterprise account, with a multi-year KAT license extended from five to seven years in September 2024. Go-to-market is sales-led and partnership-driven, leveraging the NVLF (Dutch Logopedists Association) for community distribution, universities of applied sciences for curriculum integration, and academic collaborations with the University of Amsterdam and Utrecht University through the NWO-funded ELSA Lab AI for Health Equity consortium (€2.3M, September 2025–September 2029). All revenue activity disclosed in the source material is concentrated in the Netherlands, with no stated international commercial expansion.
