Voice Control

Offline solution in 30 languages

Voice control for professional applications

Intuitive, secure and independent of network coverage

Voice control has become indispensable in many areas of everyday life. The clear advantages of voice input and output for accelerated, intuitive and contactless device operation also apply to professional applications. HY-LINE offers individual solutions for your professional and industrial applications.

While the output of signals and sounds is supplemented by synthesized speech, voice control takes its place during input. This allows devices to be operated conveniently without hands and without having to look at the device, turning the machine into a voice assistant.

Voice control is used in particular where hands are not free to operate the device, are dirty or must be sterile and must not touch anything. Offline voice control does not require an internet connection during operation. This means that data remains private and secure and can be entered in real time. The data does not have to be loaded on an external server, nor does permanent broadband access to the Internet have to be provided.



Touchless: Intuitive touchless operation

  • Artificial intelligence: statistical and semantic models created using the latest machine learning technology
  • Offline: Works directly on the device without a network connection, with low memory and CPU requirements (no AI HW required)
  • License Based: Industry-proven quality in 30 national languages
  • Industry Grade: High reliability and availability, real-time capable
  • Text to speech: Offline speech synthesis for the output of any text
  • Privacy by Design: High data security through offline execution without internet connection at runtime
  • Do What I Mean: natural language communication through NLU (Natural Language Understanding)             
  • Wake-Word: voice activation with free choice of activation word
  • Zero Coding: simple web-based voice dialog creation without programming
  • Machine interface: convenient machine interface via standardized protocols (MQTT, JSON, (S)RTP)

Technical requirements

Voice control runs on ARMv7 and higher as well as x86 platforms under Linux, Windows, Android and iOS. The voice control can run on the system processor. Typical system requirements are

  • Main memory: from 16 MByte (depending on the application)
  • Computing requirements: from 400 MIPS for real-time processing
  • Base Runtime "Dialog Manager": 10 MB
  • Speech recognition, NLU and semantic models together per language: 10 MB
  • Text to speech synthesis per language: 100 to 200 MBsorted protocols (MQTT, JSON, (S)RTP) with your device application


  • Design your individual speech dialog with the help of the provided WebSDK (Web-based Software Development Kit)
  • Deploy the voice application created in this way on your embedded system. We will be happy to advise you on suitable solutions
  • Connect the voice application to your device application via standardized protocols (MQTT, JSON, (S)RTP)
