Intelligent Microphone for eCall

NTT’s eCall unit meets all the Type 1 Double Talk performance requirements by EU and Russia:
  • Reduces the echo (the sound feedback loop) by about 30dB, making it easier to continue the conversation.
    Beamforming allows the reduction of even non-linear echo arising from speaker distortion
  • Automatically corrects the individual variables such as sensitivity and assembly of mic elements, ensuring the optimal echo removal for each device
  • Removes the echo from the beginning allowing double talk from the start (the initial setting can be done in advance based on the mic and speaker locations)

eCall is a European initiative intended to bring rapid assistance to motorists involved in a collision anywhere in the European Union (EU).
The regulation requires all new cars sold in the EU to be equipped with eCall technology from April 2018.
In the event of a serious accident, eCall automatically dials 112 - Europe's single emergency number.
