Use Case:

Voice Recognition for Portable Conference Speakerphones



Conference speakerphone with clear 360° voice capture for up to 12 people without the need to use any extension microphones. Built-in versatile connectivity to laptops/PCs/mobile phones/tablets via USB and Bluetooth. Powered by USB and built-in rechargeable lithium ion battery for portable and travel uses.


  • Noises in the background
    • HVAC system, chatter outside the meeting space, background music/TV
  • Echo heard at the far-end
    • Voice coming through the speakerphone’s speaker gets picked up by the microphones and being transmitted back to the far-end
  • Half Duplex
    • Only one person can speak at a time, the other person’s speech gets cut out
  • Distance
    • Typical distances for meetings could be 1 to 9 meters
  • Bad sound quality
    • Muffled, reverberative (“inside a tunnel”) speech
    • Other end of the call cannot easily understand the talker
  • Development
    • Aggressive schedule
    • Avoid a complete board spin
