The company is located on the scientific cluster of the Saclay plateau in France. Vocapia develops multilingual transcription engines for conversational speech and for information documents such as radio, TV and podcasts.

Beyond the standalone software, Vocapia offers services such as a REST API web service, a GUI web service called Scribe3, customer assistance and support, model customization, and specific language model development. The REST API service is available 24/7/365 with failover servers and geographic redundancy. The company targets use cases including broadcast monitoring, debate and conference call transcription, telephone speech analytics, voice interfaces, and VHF/UHF communication analysis. It also highlights applications in plenary and meeting transcription and avionics. Vocapia positions itself as a provider of sovereign solutions and expertise for core speech-processing technologies. It has participated in collaborative research programs such as the Quaero program and European projects KRISTINA, DANTE, ALADAN and KOIOS. The company remains a private, independent R&D firm.
