How To Use Speech Recognition in Windows XP

On This PageSUMMARYThis article describes how to use speech recognition in Windows XP. If you installed speech recognition with Microsoft Office XP, or if you purchased a new computer that has Office XP installed, you can use speech recognition in all Office programs as well as other programs for which it is enabled, such as Microsoft Internet Explorer.Speech recognition enables the operating system to convert spoken words to written text. An internal driver, called an speech recognition engine, recognizes words and converts them to text. The speech recognition engine may be installed with the operating system or at a later time with other software. During the installation process, speech-enabled packages such as word processors and web browsers, may install their own engines or they may use existing engines. Additional engines are also available through third-party manufacturers. These engines often use a certain jargon or vocabulary; for example, they may use a vocabulary that specializes in medical or legal terminology. They can also use different voices allowing for regional accents such as British English, or use a different language altogether such as German, French, or Russian. You need a microphone or some other sound input device to receive the sound. In general, the microphone should be a high quality device with noise filters built in. The speech recognition rate is directly related to the quality of the input. The recognition rate is significantly lower or may be unacceptable if you use a poor microphone. The Microsoft Speech Recognition Training Wizard (Voice Training Wizard) guides you through the process, recommends the best position to place the microphone, and allows you to test it for optimal results. After you have installed the system and it is working, you must train the engine for your environment and speaking style. To do so, click the Speech Recognition tab, click Train Profile, and then follow the instructions in the Voice Training Wizard to train the system to recognize background noises such as a fan, air conditioning, or other office sounds. The engine adapts to your speaking style including accents, pronunciations and even idiomatic phrases.

How to Use the Microsoft Speech Recognition EnginesThe Microsoft speech recognition engine enables you to insert text into a document using specific programs. You can dictate text in any Office XP program, in Internet Explorer, and in Microsoft Outlook Express (versions 5.0 or later). Other software programs may eventually support the Microsoft speech recognition engine. You cannot dictate text in Microsoft Notepad at this time.NOTE: Speech recognition engines are language-specific. The first three Microsoft speech engines that are available are Simplified Chinese, U.S. English, and Japanese. Engines for other languages will become available. In addition to being language-specific, some speech engines may be region-specific. For example, the Microsoft English ASR Version 5 engine is intended for speakers of U.S. English. British, Australian, other non-U.S. English speakers may have difficulty using this engine because of variations in accent.

How to Train the Speech Recognition EngineWhen you train the speech recognition engine, the speech recognizer uses the Voice Training Wizard to adapt to the sound of your voice, word pronunciation, accent, speaking manner, and even new or idiomatic words. If you train for as little as ten minutes, you can improve speech recognition capabilities. The system also adapts to your speech on an ongoing basis and recognition increases over time.To train the speech recognition engine, follow these steps:
How to Use the Speech Recognition EngineNOTE: The steps in this procedure may vary depending on the program in which you are using speech recognition.
Speech Recognition TipsSpeech recognition is not designed for completely hands-free operation; you achieve the best results if you use a combination of your voice and the mouse or keyboard. In addition, use a consistent quality of speech to achieve the best results. When you speak to others, people usually understand from the context and environment even if you whisper, shout, or talk quickly or slowly. However, speech recognition understands words better when you speak in a predictable manner.
