GIPS Acoustic Echo Cancellation -- AEC -- for IP Phones Eradicates Echo Problems in Hands-Free Mode.SAN FRANCISCO San Francisco (săn frănsĭs`kō), city (1990 pop. 723,959), coextensive with San Francisco co., W Calif., on the tip of a peninsula between the Pacific Ocean and San Francisco Bay, which are connected by the strait known as the Golden -- Version 1.1 Provides Advanced Features Including Real-World Tuning Mode and Improved Double Talk Detector Global IP Sound (GIPS GIPS - /gips/ or /jips/ [Analogy with MIPS] Giga-Instructions per Second (or possibly "Gillions of Instructions per Second"; see gillion). In 1991, this was used of only a handful of highly parallel machines and one sequential processor built with Josephson devices. ), leading provider of embedded voice-processing solutions, announced that it has enhanced its GIPS Acoustic Echo Cancellation (AEC AEC US Atomic Energy Commission Noun 1. AEC - a former executive agency (from 1946 to 1974) that was responsible for research into atomic energy and its peacetime uses in the United States Atomic Energy Commission ) for IP Phones. The module, which is part of the GIPS SoundWare(TM) suite of software modules for telephony over packet networks, allows vendors to minimize the inherent effects of echo associated with telephony handsets. Version 1.1 has been modified to enhance the sound quality of IP phones by canceling the acoustic feedback that often occurs when phones are used during hands free mode. "Echo cancellation is a critical component in creating the best possible experience for users of Voice over Packet (VoP) and Voice over IP (VoIP)," said Gary P. Hermansen, President and CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. of Global IP Sound. "Because GIPS AEC is designed to handle wideband speech, it enables manufacturers to fulfill the 'better than PTSN' promise of IP telephony. Global IP Sound will continue to create and enhance technologies that improve quality of service and drive the adoption of these powerful and useful technologies." GIPS AEC for IP Phones is optimized to eliminate echo caused by acoustic feedback that can occur between any combination of microphones and speakers in handsets, headsets and speakerphones. This highly efficient, full-duplex speech processing software package cancels acoustic feedback without audible echo or clipping. The module effectively detects and processes double talk, differentiating it from background noise, and cancels the echo. Version 1.1 of AEC more effectively handles double talk, which occurs when people talk simultaneously or interrupt each other. In addition, the new version offers flexibility to quickly and easily adjust tuning to a specific manufactures hardware and preferences, with the highest voice quality results. GIPS AEC for IP Phones ensures the highest quality with an adaptive filter, non-linear processor (NLP (Natural Language Processing) The capability of understanding human language. If the language is spoken, voice recognition plays an important role in converting the sounds to individual words. Then, natural language processing figures out what the words mean. ), comfort noise generator and a control system. The module can handle both 8 kHz and 16 kHz sampled signals, to allow for seamless interoperation with different speech codecs. The module enables speaker and conference phones, including IP phones, video IP phones and traditional circuit switched speaker phones. GIPS AEC can be readily implemented on either digital signal processors (DSPs) or general purpose processors. AEC conforms to International Telecommunications Union See ITU.

Global IP Sound now offers a broad range of echo cancellation software, which includes GIPS Acoustic Echo Cancellation for soft clients; GIPS AEC for IP Phones; GIPS AEC for softphone applications not using headphones Head-mounted speakers. Headphones have a strap that rests on top of the head, positioning a pair of speakers over both ears. For listening to music or monitoring live performances and audio tracks, both left and right channels are required. ; GIPS NEC (NEC Corporation, Tokyo, www.nec.com, www.necus.com) An electronics conglomerate known in the U.S. for its monitors. In Japan, it had the lion's share of the PC market until the late 1990s (see PC 98). NEC was founded in Tokyo in 1899 as Nippon Electric Company, Ltd. for IADs; and GIPS NEC for media gateways.
