HDClear™ – Voice Enhancement For Mobile – DBM Family

DSP Group’s DBM family of SoCs - DBMD2 (D2A3X) and DBMD4 (DSP D4A1A) - offers the ultimate noise-cancellation experience to users of mobile phones, wearable
devices, tablets, DECT wireless and wired headsets, and fixed-line corded or cordless phones.
The DBM chipsets are available in small footprints and embed DSP Group’s advanced HDClear™ technology. DBM
chipsets dramatically suppress background noise for far-end users, enhance privacy for near-end speakers, and
maximize performance of Automatic Speech Recognition (ASR) engines.

The DBMD2 chip is DSP Group’s most advanced solution for voice communications. It supports a rich set of voice processing features to significantly enhance voice call quality, intelligibility and speech recognition accuracy, including:

• Noise suppression for the far-end listener
• Noise reduction and speech conditioning for the near-end listener
• Acoustic Echo Cancellation (AEC)
• Flexispeech – variable speech playback for the hearing impaired
• Flexible Listening Experience (FLE) – automatic adjustment of incoming
  voice when the near-end listener is in a noisy environment
• Ultra-low power voice activation and voice command

DSP Group’s DBMD4 (Part number D4A1A) is an innovative audio/voice processor for smartphones, wearable and IoT devices, DBMD4 (Part number D4A1A) enables device activation and operation via voice commands while maintaining extremely low power consumption and high performance using pre-process algorithms such as noise reduction, beam-forming and Acoustic Echo Canceling (AEC).

  • High-performance, ultra-low power audio/voice DSP platform
  • Programmable DSP core
    • Autonomous operation while application processor is either in sleep mode or performing other tasks
  • Rich set interfaces
  • Small footprint
  • Comprehensive software frameworks for fast time-to-market
