ISDI International Social Development Institute ), San Jose, Calif., has introduced the first family in its VoiceDSP(TM) product line. The ISD-T360, the first pure digital engine developed by ISD, is a family of three single-chip digital voice processors providing clear sound quality, ease of integration, advanced telephony features, and voice processing for cordless and corded feature phones. The ISD-T360 is ideal for cordless phones requiring advanced answering machine functions or features like full duplex speaker phone and multi-country caller ID (types I, II, and ADSI (Active Directory Services Interface) A programming interface from Microsoft for accessing the Microsoft Active Directory (Windows 2000), the directory within Exchange and other directories via providers. ). It can also be used in a wide variety of stand-alone and integrated DTAD DTAD Digital Telephone Answering Device
DTAD Digital Terrain Analysis Data (digital telephone answering device) products as well as voice message systems. VoiceDSP products have all voice signal processing and peripheral functionality "on chip" for complete message handling, allowing for easy and seamless integration into existing designs. "The ISD-T360 is the first of a series of high performance DSPs based on our next level platform," said Avi Barel, vice president and general manager of ISD Israel. "Products developed with this new platform have unprecedented voice quality because they use one of the latest implementations of speech voice coding. In addition, our embedded DSPs will provide manufacturers the ease of integration of advanced telephony features needed to quickly get their products to market." Stefan Schauss, ISD's VoiceDSP product manager, said "The advanced telephony features of the ISD-T360 Series allows manufacturers the power and flexibility to develop high-end products ranging from stand-alone telephone answering machines to complete small office/home office See SOHO. voice mail systems." ISD-T360 Family The ISD-T360 is a family of versatile speech processors that includes interfaces to multiple codecs The following is a list of codecs. Audio codecs

This provides maximum flexibility and ease of integration in telephony applications such as cordless and feature phones. The ISD-T360 family of chips consists of three products: the ISD-T360SA, the ISD-T360SB, and the ISD-T360SC. -- T360SA -- targets high-end analog telephony products for Caller ID (type I and II) detection and decoding, full duplex speakerphone and high quality voice message management. -- T360SB -- targets high-end telephone products for digital networks with a need for full duplex speakerphone and high quality voice message management -- T360SC -- targets high-end telephone products and feature phones for customers who want to implement one DTAD solution across all their design platforms and contract manufacturers with changing target applications. It includes advanced features such as LCR See least cost routing. and ADSI for cost effective electronic commerce applications ISD-T360 Features -- Crystal clear sound quality -- Full Caller-ID support (on-hook, off-hook, ADSI) for multiple countries -- Full duplex speakerphone with echo and noise cancellation -- New improved voice/music algorithm -- Selectable master/slave codec (1) (enCOder/DECoder) A hardware circuit that performs analog-to-digital conversion (ADC) and digital-to-analog (DAC) conversion. When analog signals are entered into a computer, cellphone or other device via a microphone or video source such as VHS tape or analog TV, interface for maximum flexibility in chip-set integration -- A/DRAM and Flash support up to 64 Mbit -- Three and five volt support in the same chip Pricing and Availability The ISD-T360 product family is priced from $3.50 (US) - $5.00 (U.S.), depending on package and feature set, for quantities of 10,000 units. The product line is expected to be available in the first quarter, 1999. The Next VoiceDSP Platform -- The ISD-T460 The next ISD VoiceDSP family, the ISD-T460 will be expressly designed to be compatible with all software modules ranging from voice compression/decompression to the most advanced CID Cid or Cid Campeador (sĭd, Span. thēth kämpāäthōr`) [Span.,=lord conqueror], d. 1099, Spanish soldier and national hero, whose real name was Rodrigo (or Ruy) Díaz de Vivar. detection and decoding, and worldwide standards compliance currently developed on the ISD-T360 platform. The ISD-T460, will be a highly integrated and customizable voice processor on a chip. These devices, expected to be available in the second quarter of 1999, will integrate a DSP/RISC engine with a codec and microcontroller and will be user customizable. In addition, versions of the ISD-T460 family are also expected to feature speaker independent and dependent speech recognition and text-to-speech functions. VoiceDSP The VoiceDSP processor integrates the functions of one or more digital signal processing See DSP.
Digital Signal Processing - (DSP) Computer manipulation of analog signals (commonly sound or image) which have been converted to digital form (sampled). (DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below).

It contains system support functions such as interrupt control unit, codec interface, standard telephony interfaces, multiple memory support ranging from standard 16 Mbit A/DRAM to flash memories from various suppliers, WATCHDOG timer, a clock generator, telephony codecs, and an embedded microcontroller. The VoiceDSP firmware implements voice compression and decompression, tone detection and generation, message and data storage management, speech synthesis, and supports user-defined voice prompts in various languages. The VoiceDSP processor also applies echo and noise cancellation techniques to support high-quality DTMF (Dual-Tone MultiFrequency) The type of audio signals that are generated when you press the buttons on a touch-tone telephone. See also DMTF.
DTMF - Dual Tone Multi Frequency tone detection during message playback. VoiceDSP will also include speech recognition and text-to-speech functions. In addition, the VoiceDSP processor can synthesize messages in various languages via the International Vocabulary Support (IVS ivs - INRIA Videoconferencing System.
