voice INTER connect

What voice INTER connect does

voice INTER connect GmbH is a privately held German engineering company founded in 2001 in Dresden with a secondary office in Stuttgart. It develops embedded voice control, intercom, and audio signal processing products for European and global customers in commercial vehicles, industrial automation, emergency and security communication, railway, healthcare, and smart home segments. The company employs more than 30 engineers and specialists focused on signal processing, beamforming, acoustic echo cancellation, and noise reduction.

The technical portfolio is centered on four families. vicCONTROL industrial delivers offline, embedded natural language voice control that runs on ARM and x86 platforms with MQTT connectivity and a web-based dialog design tool. The vicCOM family covers intercom modules for door and building communication, including cellular and GSM-R variants, plus the new vicCOM CAR for emergency and commercial vehicles with automotive E1 and IP66 certification and the proprietary audioRTBUS digital bus. vicPURE supplies software libraries for hands-free speech enhancement plus MEMS microphone arrays, and vicMEDIA provides a VoIP framework for emergency call systems in elevators, public telephones, and hospitals. Supporting intellectual property includes the patented audioRTBUS and A2B microphone designs co-developed with Infineon.

Revenue is generated through three streams: hardware product sales (intercom modules, dev kits, microphone arrays, evaluation kits, plus an online shop), software licensing (vicCONTROL, vicPURE, vicMEDIA libraries), and custom engineering services covering speech dialog development, signal processing algorithm work, embedded software, hardware design, and acoustic measurements. Distribution is direct and enterprise-focused, supplemented by channel partners such as basysKom (OPC-UA integration) and Spectra (joint industrial PC product), with brand presence at embedded world, AGRITECHNICA, INTERSCHUTZ, DAGA, and SPS IPC Drives. No external funding, M&A activity, or revenue figures are disclosed, and ownership appears concentrated with managing director Dr.-Ing. Diane Hirschfeld.
