As the mobile industry becomes increasingly competitive, device manufacturers are looking to enhance audio/voice performance while meeting market requirements for low-power and low-cost solutions. Leveraging patented audio/voice processing technology in its HDMobile product line and advanced system-on-a-chip (SoC) capabilities, DSP Group® offers a range of innovative products that comprise a solution to ensure consistent voice clarity for mobile devices anytime, anywhere.
The mobile phone has greatly evolved since its introduction when it was primarily used for voice communications. Today it is a companion device, providing on-the-go features such as communications, entertainment and computing. Multi-functional smartphones offer advanced voice features such as Automatic Speech Recognition (ASR) for performing texting, dialing and other tasks.
The user experience in voice communications has suffered from background noise. Background noise affects voice clarity (voice quality and intelligibility) and caller-location privacy that can be discerned by background noise. Background noise impacts the ability to be clearly heard by the other side as well as the ability to activate ASR features, especially when a smartphone is used in handheld speakerphone mode.
Mobile Network Operators (MNOs) and device makers require a solution that reduces background noise to improve customer satisfaction and loyalty. They also require a solution that maximizes ASR accuracy in all surroundings, even when the device is used in handheld speakerphone mode. Such a solution, however, cannot compromise mobile users' "traditional" requirements – a small, thin device with a long-lasting battery at a low cost.
DSP Group has developed the HDMobile product line to meet these demands. Featuring the HDClear™ DBM chip series with small footprints, a software platform and patented audio/voice processing technologies HDClear dramatically enhances voice communications. Even in noisy surroundings and when a handset is used in handheld speakerphone mode, HDClear delivers unparalleled voice clarity. This enables HDClear to maximize the accuracy of popular automatic speech recognition (ASR) applications. HDMobile products are ideal for devices such as smartphones, tablets, notebooks, Bluetooth and DECT wireless headsets.
