voice INTER connect and PHYTEC have jointly developed a voice control system for embedded systems. For this, the vicCONTROL industrial voice control of voice INTER connect was integrated on the phyBOARD-Mira. This industrial solution requires no Internet connection after implementation and is thus suitable for data protection-sensitive projects. Conventional operating methods can be extended by voice control easily and inexpensively. Hands-free input systems, intuitive controls, and vandal-proof user interfaces can be implemented.
Embedded Voice Control with vicCONTROL industrial and phyBOARD-Mira
The custom application for voice control is created using the web-based development environment vicSDC. The created speech dialogues and operating sequences are loaded onto the embedded system and processed locally by vicCONTROL industrial. In terms of performance, vicCONTROL industrial is in no way inferior to cloud-based speech recognizers such as Amazon's Alexa or Google Home and is furthermore available in 30 national languages.
- SDK for embedded ARMv7 compatible platforms
- Convenient API for using voice input and output via MQTT
- Web browser based dialog designer "vicSDC" with examples for developing custom voice control
- Industry proven quality in 30 national languages
- Wake-up Word feature
- Semantic evaluation of recognized speech commands
Dialog design and transfer
Speech recognition and processing
- Runtime: minimal 6 MByte
- Language model: max. 6 MByte per language
- Application-specific language resources:
approx. 10 kByte simple command control with 10 words
approx. 500 kByte comprehensive command control with 1000 words
- Main memory: minimal 10 MByte (depending on the application)
- Computational requirements: approx. 400 MIPS for real-time processing
With the voice control kits using i.MX 6 processor, vicCONTROL industrial is ready-to-use out of the box. These kits allow a direct integration into an application development and demonstrates the performance of the system based on the demos.
Two kit variants are available: the Voice Control Kit 1 with voice recognition adapter and two microphones for echo- and noise suppression, and the Voice Control Kit 2 with additional adaptive Beamforming. This allows for the acoustic detection of the person speaking and the greatest possible suppression of ambient noise. Thus it is also suitable for use in loud environments. The microphone array with seven microphones can also be positioned remotely (connection via RS485 or Ethernet).

The phyBOARD Mira is cost-optimized, suitable for series and industrial use. This Board is well-stocked and can be used directly in your project - including the voice control of voice INTER connect. Of course, we can also adapt the single board computer to your specifications or develop completely individual electronics, including a BSP, for you. Upon request, we can also take over commissioning, EMC and environmental tests as well as stability tests of the software, etc.
