Hands-free kits and in-vehicle hands-free systems have been around for many years. The technology for these systems isn't standing still, though; changes introduced by automotive OEMs, the network, as well as increasing customer expectations are driving many new innovations.

For example, wideband technology being introduced in Europe allows for greater call fidelity, but also, unfortunately, transfers more road noise. Sophisticated algorithms can remove noise from wind or defroster vents, allowing freedom in microphone placement without requiring complete system tuning for each vehicle.

An affliction prevalent in the automotive industry is the "Audio Is Easy" syndromealso known as AIE syndrome. Symptoms include the illusion that all hands-free speech communications in an automobile requires a microphone and loudspeaker connected to a network access device.

Delivering high-quality hands-free speech communications in an automobile is unfortunately not simple. It requires a thorough understanding of how to measure performance and of common causes of performance issues, and the application of the best available solutions to solve these performance problems.
