speech-recognition

I have need to write an application which uses a speech recognition engine -- either the built in vista one, or a third party one -- that can display a word or phrase, and recognise when the user reads it (or an approximation of it). I also need to be able to switch quickly between languages, without changing the language of the operating system. The users will be using the system for very short periods. The application needs to work without the requirement of first training the recognition engine to the users' voices. It would also be fantastic if this could work on Windows XP or lesser

I'm trying to recognize speech with Windows 7 but it always recognizes a speech as a command or just says "What was that?". How I can get all speeches? CODE: SpeechRecognizer _speechRecognizer; public Window1() { InitializeComponent(); // set up the recognizer _speechRecognizer = new SpeechRecognizer(); _speechRecognizer.Enabled = false; _speechRecognizer.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(_speechRecognizer_SpeechRecognized); } Perhaps you want to use the .net System.Speech namespace instead of SAPI? There is a very good article that was published a few years ago
