Voice Control

Offline solution in 30 languages

Today, voice operation is indispensable in many areas of daily life. The clear advantages of input and output via voice for accelerated, intuitive and touch-free device operation apply just as much in professional areas of application. HY-LINE offers individual solutions for your professional and industrial application.

While the output of signals and tones is supplemented by synthetic speech, voice control takes its place in input.
Thus, devices can be operated comfortably without hands, without looking at the device and the machine becomes a voice assistant.
Voice operation is used especially in places where hands are not free to operate the device, are dirty, or must be sterile and not touch anything.

Offline voice operation does not require a connection to the Internet during operation. As a result, data remains private and secure, and input can be made in real time. Data does not need to be loaded on an external server, nor does broadband permanent access to the Internet need 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 output of arbitrary texts
  • 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 speech dialog creation without programming
  • Machine Interface: comfortable machine interface via standardized protocols (MQTT, JSON, (S)RTP)

Technical requirements

Voice Control runs on ARMv7 and higher and x86 platforms on Linux, Windows, Android and iOS. Voice control can run on the system processor as well. 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 MB




  • Design your individual speech dialog using the provided WebSDK (Web-based Software Development Kit).
  • Deploy the so created speech application on your embedded system. We are happy to advise you on suitable solutions
  • Connect the speech application to your device application via standardized protocols (MQTT, JSON, (S)RTP)
