Due to the growing usages of mobile phone, the integration of hands-free system into vehicle systems for user convenience, and also to address driver safety concerns, has grown tremendously during recent years. Integration of hands-free voice communications into automotives have remained a challenging topic. The varying road noises, wind noises, engine and fan noise all poses difficulties to maintaining in-vehicle voice call quality, the coupled acoustic echo also creates difficulties for full-duplex communications.
Fortemedia’s Small Array Microphone (SAM™) based voice processing ASICs have a long history of deployment in automotive built-in and hand-free devices. SAM™ technology contains innovative signal processing techniques to suppress the non-stationary interferences such as road and wind noises, and also< to reduce the stationary engine and fan noises. SAM also eliminates any echoes coupled from the loudspeaker into the microphones to allow natural full-duplex echo-free conversations.

In recent years, Fortemedia has invested in test equipment and facilities for meeting the VDA-HFT industrial standard. These VDA-HFT test equipment facilities not only ensure that Fortemedia characterizes, optimizes, and tests its hands-free products to meet the highest voice quality standard in automotive applications, the equipment are also available to help Fortemedia customers on various aspects of integration support and testing.
