- OpenSpeech Recognizer 3.0 provides speech recognition in 44 languages and dialects and additional languages can be developed on a custom basis to meet the needs of specific applications.
- OpenSpeech Recognizer 3.0 offers full multilingual capabilities that allow any combination of languages to be mixed within a single utterance. This feature is valuable in bilingual markets where callers often switch between languages in a single response. For example, in Canada it might be used to seamlessly recognize responses combining English and French.
- Patented LEARN capabilities continually and automatically adapt the recognizer to each specific deployment. LEARN quickly adjusts acoustic models to local dialects, regional accents and telephony channel characteristics. The net result is measurably improved recognition accuracy without any additional effort, even if caller demographics shift over time.
OpenSpeech Recognizer 3.0 creates a unique best-of-breed design, drawing on carefully selected algorithms, development techniques, and components employed in the SpeechPearl® and OpenSpeech Recognizer product lines. This approach delivers a single, feature-rich speech recognition product to service the global speech recognition market, lowering development, sales and support costs for telephony platform developers. Enhanced features of OpenSpeech Recognizer 3.0 include the following: - Core technology improvements have reduced recognition error rates by an average of 25% on a variety of tasks compared to OpenSpeech Recognizer 2.0. Fewer recognition errors lead to greater caller satisfaction, higher call completion rates and a faster return on investment.
- OpenSpeech Recognizer 3.0 incorporates techniques such as Finite State Transducers (FST) to reduce memory and CPU consumption without compromising recognition accuracy, increasing channel density and so lowering overall system cost. Savings of 90% can be realized for large grammars.
- OpenSpeech Recognizer 3.0 features new algorithms for more accurate confidence scoring, reducing the need to prompt for confirmation of inconclusive recognition results. This reduces individual call times to expand call handling capacity while raising caller satisfaction.
- OpenSpeech Recognizer 3.0 is available in all-in-one and client-server architectures sharing a common API that is backwards compatible with OpenSpeech Recognizer 2.0. In addition, support for MRCP is available from the newly updated SpeechWorks MediaServer 3.0, which also includes Speechify® text-to-speech, providing customers with more deployment options.
