Acoustic Technologies Now Shipping ATS5500 Speakerphone Software.Business Editors/High-Tech Writers MESA, Ariz.--(BUSINESS WIRE)--April 21, 2004 SoundClear(R) Software for Mobile Handsets Provides Enhanced Speakerphone Performance for Mobile Conferencing, 3G Video Calling, and Hands-Free Operation Acoustic Technologies, a leading developer of high quality communication solutions for voice telephony, today announced the immediate availability of its next generation SoundClear(R) ATS5500 software for cellular speakerphones. Based on the success of the first generation SoundClear product for mobile handsets, this enhanced software improves voice clarity, full-duplex operation and speaker volume. The ATS5500 SoundClear cellphone (CELLular telePHONE) The first ubiquitous wireless telephone. Originally analog, all new cellular systems are digital, which has enabled the cellphone to turn into a smartphone that has access to the Internet. software utilizes the DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive already embedded in the cellular handset to provide crisp, clear speakerphone operation for mobile conferencing, 3G video calling and hands-free operation. As PDA (Personal Digital Assistant) A handheld computer for managing contacts, appointments and tasks. It typically includes a name and address database, calendar, to-do list and note taker, which are the functions in a personal information manager (see PIM). and Internet 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 products that solve the problem of poor speakerphone sound quality in mobile handsets caused by echoes and harsh noise environments. SoundClear software enables natural conversation and simultaneous access to voice, data and video. SoundClear optimizes speech intelligibility Noun 1. speech intelligibility - the intelligibility of speech (usually measured in the presence of noise or distortion) intelligibility - the quality of language that is comprehensible in cellular applications with full-duplex control that adaptively monitors, detects and processes incoming voice, echo and noise signal power levels. "SoundClear ATS5500 software is a highly integrated voice processing The computerized handling of voice, which includes voice store and forward, voice response, voice recognition and text to speech technologies. system, designed to deliver full-duplex speakerphone performance for cellular phones merging voice, data and video. SoundClear enables natural-flowing speakerphone operation that will help proliferate mobile conferencing into the business environment and will create greater demand for 3G services being offered by operators," said Sam Thomasson, Acoustic Technologies 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. . The SoundClear ATS5500 software is much more than just an acoustic echo canceller See echo cancellation. . The system integrates acoustic echo cancellation The elimination of an echo in a two-way voice transmission. Echo is created in the telephone company's central office switch when two-wire lines from the customer are converted to four-wire lines for backbone trunks. , noise cancellation (1) The elimination of unwanted signals in an electronic circuit. See noise and dynamic noise reduction. (2) The elimination of unwanted noise in the environment using noise cancelling headphones. , sound enhancement and full-duplex control that work together to provide the SoundClear advantage. Dramatic improvements in sound quality are achieved through a combination of patented techniques. Optimized for full-duplex operation and improved sound quality in harsh noise environments where handsets are commonly used, key features of the SoundClear software include more than 42dB total echo rejection, no distortion or speech clipping, and dynamic adaptation to changing conditions such as noise, speech levels and delay. The ATS5500 software provides fast convergence to changing conditions, even in the presence of background noise. SoundClear software is configurable for various audio performance demands and system constraints. The ATS5500 is available for Texas Instrument's C54x and C55x families. The solution is optimized for high voice clarity with efficient use of MIPS (Million Instructions Per Second) The execution speed of a computer. For example, .5 MIPS is 500,000 instructions per second; 100 MIPS is a hundred million instructions per second. and memory. The software is written as fixed-point DSP code and is portable to other commercial or proprietary DSP architectures.
