Enhanced Speakerphone Performance in 3G Phones

17th August ,2004

US : Acoustic Technologies, a leading developer of high quality communication solutions for voice telephony, today announced the expansion of its software solution through a new licensing agreement that integrates SoundClear ATS5500 software into select Motorola 3G mobile phones.

The SoundClear software improves voice clarity, full-duplex operation, and speaker volume, enabling natural flowing communication for video conferencing and hands-free speakerphone operation.

As data functions merge into the cellular handset, integrated speakerphones are essential for simultaneously talking on the phone and accessing data or viewing video. Mobile users and network operators are demanding speakerphone solutions with improved sound quality that also mask echoes and harsh noise environments. SoundClear software enables natural conversation and simultaneous access to voice, data, and video for improved speakerphone performance.

“As the 3G cellular marketplace continues to grow, voice quality remains a critical factor for success,” said Sam Thomasson, Acoustic Technologies CEO. “SoundClear software raises the bar for video conferencing and hands-free operation performance in today’s 3G-enabled devices by providing flexible speakerphone capabilities that enhance the overall mobile user experience. Our solution enables natural-flowing speakerphone operation that will help propel mobile conferencing in the business environment and create greater demand for 3G services worldwide. Acoustic Technologies is proud to work with Motorola to provide the highest quality voice technology for their 3G mobile phones.”

With full-duplex control, SoundClear optimizes speech intelligibility in cellular applications and adaptively monitors, detects, and processes incoming voice, echo, and noise signal power levels. This eliminates the misunderstanding that comes from syllable or word clipping. By providing a combination of echo cancellation, bi-directional noise reduction, and sound enhancement along with sophisticated monitoring and control algorithms, SoundClear software maximizes listener experience while minimizing distortion. In addition, the software also adapts quickly to changing environments and enables natural communication flow - similar to a face-to-face conversation – which is especially helpful for video and speaker modes on mobile devices.

SoundClear software is initially expected to be available on Motorola’s A1000 and E1000 3G mobile phones. The SoundClear software supports both single and multi-speaker implementations and is compliant with 3GPP, G.167, and G.168 standards.
