Embedded ViaVoiceA single, fully integrated architecture The modular Embedded ViaVoice architecture provides fully integrated, automatic speechrecognition, speech synthesis through text-to-speech (TTS) and other technology enginessupporting the full-feature requirements of an application with minimal processor utilization and

memory requirements. A single architecture with consistent application interfaces enablesEmbedded ViaVoice to support solutions from low-resource Personal Navigation Devices to high-performance in-vehicle solutions to Java technology. This single-architecture implementation is aparticular advantage to applications that need to span a broad range of platform capacities, as wellas solutions where significant growth in capacity is a requirement.A broad language base Embedded ViaVoice is available in a broad set of languages to provide speech-recognition andspeech-synthesis capabilities through the support of a worldwide network of IBM speech researchand development laboratories. High-quality embedded concatenative TTS (eCTTS) capabilitiesprovide more-human-sounding speech synthesis to support more-advanced applications. To learnmore about IBM's continuing development of other language models for ASR and voices for TTS, aswell as its continuous improvement of existing languages, contact your IBM representative.High recognition accuracy The Embedded ViaVoice recognition engine is based on small units of speech, called phonemes.This phoneme-based model uses finite state grammars to support highly accurate and noise-robust,continuous speech recognition. Through a comprehensive and vigorous research and developmenteffort, IBM has significantly reduced the word-error rate of Embedded ViaVoice over the past severalyears.Large vocabulary recognition The maximum vocabulary supported by Embedded ViaVoice has grown by a factor of 25 over thepast four years. Embedded ViaVoice supports the recognition of lists of a virtually limitless number of words, bounded only by the platform's processing and memory resources.Services and workshops Porting and integration services include porting to a new operating system, recompiling for differentprocessor architecture or modifying the embedded audio layer to use a new driver or codec.

Alternatively, with a device adaptation kit, IBM supplies the tools that enable you to perform and testthe audio adaptations yourself.IBM can provide on-site classes to application developers about the Embedded ViaVoice SoftwareDeveloper Kit (SDK). Customized development workshops are also available to provide skillstransfer and instruction on application development, evaluation methodology and tools, so you candesign and tune your own system to suit your organization's business needs.Support for multiple programming models Many small-footprint, embedded applications use Embedded ViaVoice through its C/C++ languageapplication interface.IBM expertise in voice IBM's sustained research and development investment in speech recognition and synthesis for morethan 30 years has resulted in multiple advances, including Embedded ViaVoice. IBM EmbeddedViaVoice software enables you to gain competitive advantage in today's fast-moving marketplace -and offers a clear path to future growth through a single, fully integrated architecture.Functionality
