`is maximized
`technology
`the
`applications, it can support many different audio
`providers on multiple IVR platforms, and its
`supported availability across multiple UNIX and
`NT platforms allows users to take advantage of
`continuing hardware improvements. Nuance 6
`supports
`small and
`large applications with
`vocabularies from two to 15,000+ words, and
`easily
`accommodates
`variable
`capacity
`requirements. Because the RecClient provides a
`consistent
`interface
`to
`the application,
`the
`application does not have to be recompiled to
`support different audio providers (like telephones
`and microphones) on the same IVR platform.
`
`Unmatched recognition accuracyNuance’s approach to speech recognition achieves
`a very fine acoustic resolution, and therefore a
`higher degree of accuracy and a better ability to
`handle
`large-vocabulary
`applications.
` By
`partitioning the digitized speech signal into a
`sequence of short
`frames, and
`then using
`algorithms and statistical processes to analyze the
`data, the RecServer determines the words or
`phrases that were spoken. To optimize the
`accuracy of the RecServer, Nuance uses a unique
`combination of Hidden Markov Models, a
`statistical technique that integrates linguistic rules
`and training from recorded speech databases, and
`innovative Gaussian-mixture processing.
`
`Natural language understandingOnce the RecServer has recognized the speech, it
`uses a
`template-matching natural
`language
`approach to determine meaning. This means the
`RecServer takes the relevant pieces of recognized
`speech and matches them against a customized
`template of pre-specified information. This
`template
`approach
`is more
`robust
`and
`sophisticated
`than word spotting or “tag”
`approaches and easier and more efficient than an
`application-specific sentence parser.

`
`Nuance 6, the core client/server software in the
`Nuance
`Communications
`product
`suite,
`combines unparalleled accuracy and natural
`language
`understanding
`to
`extend
`the
`performance advantage of Nuance in speech
`recognition applications.
` Utilizing advanced
`linguistic and statistical models to interpret and
`understand natural human speech, Nuance 6
`enables
`sophisticated
`speech
`recognition
`applications that allow users to talk to computers
`as if they were speaking with human agents.
`Nuance 6’s open, scalable software architecture,
`comprised of the Nuance RecServer™, Nuance
`Resource Manager™
`and
`the Nuance
`RecClient™, makes efficient use of hardware
`resources
`to allow
`the
`implementation of
`affordable,
`flexible
`speech
`recognition
`applications
`that give users a competitive
`advantage in today’s rapidly changing business
`environment.

`allows

`distributed
`Powerful client/server software architectureNuance’s
`recognition to happen on a separate stand-alone
`machine or network of servers, expediting the
`recognition process and resulting in memory
`savings. This
`is achieved by simultaneously
`sharing recognition data objects that can be
`shared across multiple recognition searches. By
`dynamically allocating recognition resources with
`the Resource Manager, Nuance 6 capitalizes on
`the
`efficiency of processing of multiple
`recognition requests in parallel and provides
`automatic fail-over protection in the event of a
`hardware or
`software
`failure.
` Nuance’s
`client/server architecture also allows applications
`developers to decouple audio acquisition from
`recognition processing. The RecClient performs
`all audio and telephony functions required by
`speech applications, including echo cancellation
`and endpointing when DSP is unavailable, and
`manages the collection and transmission of
`speech to the multi-threaded RecServer. The
`RecServer itself handles speech recognition and
`understanding. This allows the application to
`focus on call-flow and dialog management,
`resulting ultimately in a more seamless interaction
`with the end user.
`
`Open and scalableSpeech recognition solutions built with Nuance 6
`provide tremendous flexibility and choice because
`Nuance software is open and fully scalable. While
