Introduction
Welcome to the NLP-5x and the world of low-cost, high-performance speech recognition! The resources in the
NLP-5x Demo/Emulation Toolkit
will allow you to produce innovative and powerful products that feature a high
level of system integration using low-cost leading-edge speech technologies. This manual discusses the use of
these resources for evaluation and development purposes. It assumes the reader is an experienced software
developer who understands C language programming and embedded systems development methods, but who
may not be specifically familiar with Sensory’s ICs.
This Toolkit supports the NLP-5x only. It cannot be used to develop products for the RSC-164, 264, 364,
4128 or SVC families of chips.
Included in the NLP-5x Demo/Emulation Toolkit
NLP-5x Demo/Emulation board (60-0258), featuring a NLP-5x running in emulation mode and all of the
components necessary to evaluate Sensory’s speech technologies.
USB Cable
(2) Speakers
Wall-Mount Power Supply (120V) 9VDC
NLP-5x Toolkits Installer (Download from ftp://ftp4.sensoryinc.com/software/nlp5x/nlp5xtoolkit.zip)
Complete Documentation including NLP-5x Demo/Emulation Manual (80-0314-x)
(this manual) — For use as a Quick Start Guide
FluentChip™ 5 for NLP-5x Technology (FC5) Library, with speech recognition technologies
including T2SI™ speaker-independent (SI), speaker-dependent (SD), speaker-verification (SV),
plus speech and music synthesis, MP3 decoding, and a variety of other technologies
“QuickSynthesis™ 5” (QS5), which allows speech to be compressed for low data-rate synthesis
“SensoryLoader5” (SL5), which is used to download programs to the NLP-5x
Programming/Verification Board
This toolkit works in conjunction with:
ZView Tools for NLP-5x, which includes the ZViewIDE and the ZView C compiler.
Quick T2SI™ Toolkit for NLP-5x (sold separately), which can be used to create speaker-independent
recognition sets by simply typing the vocabulary into a PC based GUI and downloading it to the NLP-5x
Demo/Emulation board.
The NLP-5x provides the following technology features important for low-cost consumer products:
Wide operating voltage range (2.0 to 3.6V)
Power-down sleep mode to conserve power
Pulse Width Modulator (PWM) to directly drive an 8-ohm speaker
Stereo D/A converters (DACs)
Integrated microphone amplifiers requiring only a few additional passive components
Ability to interface to optional external parallel and serial memories
Developing a product that effectively integrates Sensory’s speech technologies requires hardware platform
development, software development, product integration, and human-interaction testing. For the best speech
recognition performance, each of these design areas should be error-free. Sensory helps to facilitate successful
implementation by providing free design consultations and product reviews. Refer to the Speech Recognition
Hardware Design Guide (80-0073-x) for more details.
