Libre Wireless Technologies, an embedded voice enabled audio and multiprotocol IoT solution provider, is using DSP Group’s SmartVoice technology for its fully integrated LS5BV LibreSync voice and media streaming module.
The LS5BV module includes DSP Group’s HDClear SoC with sophisticated algorithms for detecting and processing far field voice, including advanced noise reduction, echo cancellation, music barge-in and audio processing features. It is designed to support from 1 to 3 mics, giving customers flexibility for various applications that can be optimized for cost, front facing 180 or circular 360 degree applications.
The LS5BV offers a clean interface to off-module mics allowing the product designer flexibility on mic placement and product integration while providing a simple low-cost interface in a fully integrated mic-to-cloud voice solution.
DSP Group’s HDClear SoC is an audio/voice SoC for IoT devices as smart speakers which enables far-field device activation and operation via voice commands while maintaining low-power consumption and high performance using pre-process algorithms such as noise reduction, beam-forming and Acoustic Echo Canceling (AEC) for barge-in mode using 1 to 3 mics.
“We are thrilled to work with Libre Wireless Technologies on their new LibreSync module. It is an incredibly sophisticated yet fully integrated hardware and software solution that delivers the ultimate in IoT voice technology, audio streaming and multi-room and unique concurrent operation of voice/ASR and multiple playback sources,” said Yosi Brosh, CVP SmartVoice Sales & Marketing at DSP Group.
The LibreSync module will help ensure that Libre customers are out in front of the fast-moving world of connected voice assistant products with this new size, power and cost optimized turn-key product, Brosh added.
“The high integration and high efficiency and low-power operation of voice processing algorithms attracted us to DSP Group’s HDClear SoC,” said Hooman Kashef, CEO of Libre Wireless Technologies. “DSP Group brings decades of experience in voice processing to Libre, and their technology is helping us to deliver maximum flexibility in size, cost, features and low power to our customers.”
