ISD UNVEILS "VOICEDSP" DIGITAL VOICE PROCESSORS FOR PHONES.
ISD (Information Storage Devices, Inc.) (Nasdaq:ISDI), 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). It can also be used in a wide variety of
stand-alone and integrated DTAD (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 voice mail systems."
ISD-T360 Family The ISD-T360 is a family of versatile speech processors
that includes interfaces to multiple codecs and provides support for
single and dual codecs as well as PCM and other speech interfaces. 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 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 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 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 (DSP) modules and 16-bit and 32-bit general-purpose RISC core
architectures. 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 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) mechanism.
