How accurate in terms of percentage of words recognized are current speech recognition programs?
95 percent
The current generation of continuous speech recognition systems claims to offer high accuracy (greater than 95 percent) speech recognition at natural speech rates (150 words per minute) on low-cost (under $2000) platforms.
What is the fastest speech of words per minute that speech recognition systems can recognize speech *?
John Moschitta, Jr., had held the Guinness World Records as the World’s Fastest Talker, with the ability to speak 586 words per minute. His record was broken in 1990 by Steve Woodmore who spoke 637 words per minute and then by Sean Shannon, who spoke 655 words per minute on August 30, 1995.
Is speech recognition faster than typing?
Speech recognition software can easily transcribe over 150 words per minute (WPM), while the average doctor types around 30 WPM. Stanford researchers studying typing versus dictation found that speech recognition was nearly three times faster while also producing fewer errors.
What is the importance of speech recognition?
Speech recognition enables hands-free control of various devices and equipment (a particular boon to many disabled persons), provides input to automatic translation, and creates print-ready dictation. Among the earliest applications for speech recognition were automated telephone systems and medical dictation software.
How to manage speech recognition grammars in speech recognition?
To manage speech recognition grammars, use the LoadGrammar, LoadGrammarAsync, UnloadGrammar, and UnloadAllGrammars methods, and the Grammars property. To configure the input to the recognizer, use the SetInputToAudioStream, SetInputToDefaultAudioDevice, SetInputToNull, SetInputToWaveFile, or SetInputToWaveStream method.
What is speech recognitionprovide?
Provides the means to access and manage an in-process speech recognition engine. The following example shows part of a console application that demonstrates basic speech recognition. Because this example uses the Multiple mode of the RecognizeAsync method, it performs recognition until you close the console window or stop debugging.
How do I perform speech recognition with unexpected input?
To perform speech recognition, use the Recognize or RecognizeAsync method. To modify how recognition handles silence or unexpected input, use the BabbleTimeout, InitialSilenceTimeout, EndSilenceTimeout, and EndSilenceTimeoutAmbiguous properties.
What is the speechrecognitionengine class for?
This class is for running speech recognition engines in-process, and provides control over various aspects of speech recognition, as follows: To create an in-process speech recognizer, use one of the SpeechRecognitionEngine constructors.
