21ic News CSR has announced that it provides extensive platform support for the newly approved HFP 1.6 Bluetooth specification; the HFP 1.6 Bluetooth specification covers broadband voice - commonly referred to as HD voice or HD voice. CSR's BC6145 is the first mass-market mono headset solution to support this new hands-free specification, enabling OEMs to immediately produce high-quality HD voice products.

CSR has designed HD voice support for a variety of handset products, headsets and automotive applications, and plans to support this new specification on a variety of platforms.
A number of mobile network operators are now launching high-definition voice services to provide users with clearer sound quality. At the network level, HD voice provides a wider voice spectrum than ever before. As the speech spectrum increases from 300Hz–3.4kHz to 50Hz–7kHz, even in noisy environments, consumers will be able to understand speech content more easily. Other foreseeable advantages include more accurate voice control for peripheral accessories, better text-to-speech conversion, and higher audio quality, giving the caller a sense of distance.
Therefore, the application of the Bluetooth HFP 1.6 specification on cellular devices and Bluetooth accessories will enable the network HD voice service to be extended via Bluetooth. This is to eliminate the limitation of the 8 kHz sampling rate and the resulting high and low speech frequency loss. Conversely, users can enjoy 16 kHz resolution, the call will be more natural, and voice dialing and many other features will be improved.
Anthony Murray, vice president of audio and consumer business at CSR, said: "Today marks two major advances: the long-awaited Bluetooth Technology Alliance is the first to release a new HFP 1.6 specification that supports broadband voice, and the CSR audio platform that complies with the HFP 1.6 specification. Bulk supply - they will work together to promote HD voice in mainstream devices."
Murray continues: "As more and more mobile network operators begin to offer high-definition voice technology, users can use hands-free calling with the BC6145 Bluetooth headset and car kit, and will continue to discover the unique value of HD voice. â€
CSR's BC6145 is targeted at single-microphone mono headsets, speakers, car kits and other mass-market wireless audio accessories. In addition to high-definition voice, the BC6145 will support a full range of compelling, user-oriented features, including A2DP music streaming capabilities, advanced understanding enhancements, and longer talk time. The BC6145 also supports two-way noise suppression and ultra-low power wind noise suppression (WNR), which are expected to greatly enhance the user experience.
In addition to the fastest-to-reach BC6145, CSR has several other platforms that support HD voice at all times, including the CSR8000 connectivity platform and BlueCore5-Multimedia for headsets and other applications. CSR's in-vehicle and PND business units are also developing automotive-grade solutions for high-definition voice on a wide range of mobile communications devices today, including mobile phones, factory-origined automotive applications, and aftermarket vehicles.
