CSR has released an initiative, which will support the accelerated uptake of Bluetooth based handsfree kits, thus spreading safer and more convenient use of mobile phones by drivers around the world.

The CSR RoadRunner Plug-n-Talk is the first in a series of ready engineered and fully-interoperable automotive solutions from CSR that provides OEMs and ODMs with a pre-tested and customisable package from which to create a low-cost Bluetooth handsfree kit. The package also forms a robust foundation on which more integrated and advanced handsfree functionality can be designed into car models.

Recent industry estimates suggest that the market for Bluetooth-enabled vehicles is set to grow annually at a rate of more than 25 percent from 2005 to 2010. According to CSR, this growth is being driven by global consumer adoption of Bluetooth technology and a desire to be able to use their mobile handsets to make productive use of time in the car, without compromising on safety or personal comfort. The Roadrunner reference design will allow OEMs and ODMs to capitalise on this growth and meet the demands of their customers for low-cost Bluetooth handsfree systems in the car.

The RoadRunner Plug-n-Talk system features a full hardware reference design, Bluetooth stack, profile suite, handsfree application software and CSR’s proprietary Clear Voice Capture (CVC) software. The addition of CVC to the design improves voice quality by combining advanced echo and noise suppression algorithms, which allow the speaker’s voice to be more clearly extracted and transmitted to the caller at the other end of the line. In addition, it includes a demonstration of text-to-speech software from NowSpeak, which has been developed specifically for CSR’s BlueCore-Multimedia technology.

More complex and superior handsfree functionality can be designed-in with features such as caller ID confirmation and voice prompts during handsfree operation. Furthermore, by using the configuration tool supplied, designers can change the Flash parameters and modify elements like the MMI, call handling, PIO assignment to buttons and ring tones. The RoadRunner Plug-n-Talk system allows designers to customise the look, feel and operation of the system without having to change any code or disrupt the pre-established Bluetooth device interoperability.
