Microsoft Windows Highly Intelligent Speech Recognizer: Whisper

Since January 1993, we have been working to refine and extend

Sphinx-II technologies in order to develop practical speech

recognition at Microsoft. The result of that work has been the

Whisper (Windows Highly Intelligent Speech Recognizer).

Whisper represents significantly improved recognition efficiency,

usability, and accuracy, when compared with the Sphinx-II

system. In addition Whisper offers speech input capabilities for

Microsoft Windows and can be scaled to meet different PC

platform configurations. It provides features such as continuous

speech recognition, speaker-independence, on-line adaptation,

noise robustness, dynamic vocabularies and grammars. For typical

Windows Command-and-Control applications (less than 1,000

words), Whisper provides a software only solution on PCs

equipped with a 486DX, 4MB of memory, and a standard sound

card and a desk-top microphone.
