The Nuance Mobile Speech Platform utilizes a thin client-server model that includes the following components: Nuance Mobile Speech Platform Server, Nuance Mobile Speech Platform Client, and Nuance Mobile Speech Platform SDK.

• Nuance Mobile Speech Platform Server
  A highly scalable multimodal application server designed to meet the needs of large commercial deployments, and operate in existing and next-generation wireless network infrastructures (e.g. GPRS, CDMA 1xRTT, EDGE and W-CDMA). Utilizing Nuance's innovative state and modality management architecture to seamlessly integrate voice and data infrastructures at the application server level, the server allows both channels to be used simultaneously.
• Nuance Mobile Speech Platform Client
  A small-footprint software plug-in that manages multimodal interactions between devices and the X|mode Server; can be easily downloaded into the handset by the end user or pre-installed by the device manufacturer. Supported environments include Symbian 6.1/7.0, Nokia Series 60, UIQ, Microsoft Pocket PC and Smartphone, J2ME, BREW, and Windows CE/NT/2000/XP.
• Nuance Mobile Speech Platform SDK
  An XML-based authoring suite that simplifies multimodal application development and maximizes time-to-market of multimodal offerings.

User Benefits

• Significantly more user-friendly and intuitive interface (more useful, responsive and appealing to users), compared to data-only or speech-only interfaces.
• Simpler retrieval and visualization of information (voice in > visual out).
• Less frustration when speech recognition does not work perfectly (visual feedback and n-best, on-screen disambiguation).
• Improved access to existing speech-activated applications and services (e.g. directory assistance, navigation guides).

Service Provider Benefits

• Increase Revenues
  Increase ARPU through novel multimodal-enabled service offerings, more natural and appealing to users than existing data-only or speech-only services (e.g. multimodal directory services, navigation and location-based guides, messaging), leveraging new 2.5G billing models to offer enhanced services to subscribers, at incremental monthly fees (or 'per use' fees).
• Reduce Costs
  Reduce operational costs of call center-based services (e.g. 411 / directory assistance, customer care) by automating subscriber interactions. Multimodality enables full automation, and eliminates the need for operator fallback by offering the user more appealing and easy-to-use interfaces.
• Increase Customer Satisfaction
  Give subscribers applications that they actually want to use through superior multimodal interface usability and efficiency, adding significant value to subscribers' day-to-day activities.
• Increase Competitive Edge
  Multimodal offerings create unique branding and multimedia opportunities that allow service providers to differentiate its services and overall offering from competitors.
