Cyberon DSpotter is a local voice trigger and command recognition solution with robust noise reduction that consumes very low resources and provides high-accuracy performance. It runs on RA MCU Family and supports multiple languages as well as many connectivity function and security capable depending on the selected MCU.


  • Local voice recognition algorithm, no network connectivity needed
  • Phoneme-based modeling
    • Quick command customization: don’t have to collect speech data in advance
    • Optimization by model adaptation just with small amount speech data
  • Global language support: 44+ languages worldwide
  • Small footprint (Flash : 200KB + 28B*Xc, RAM: 50KB+116*Xc) and cost effective (single DMIC + RA6E1 or RA4E1)
  • DSMT Tool: wake-word and commands customization, performance tuning, testing, no-prior neural network knowledge needed.
  • Separation of recognition engine and command model, switching commands dynamically
  • Low power and high efficiency RA MCU with strong security function



  • IoT devices
  • Home appliances
  • Wearable/Hearable devices
