Remember that a voice input software was popular for a period of two or two years ago, most of them are based on IBM voice entry software, but because the processing speed of the computer has not reached a high level The level does not form a climate. Now with the continuous improvement of the computer frequency, even Windows XP has built-in voice recording software. How is it used? Let us have a look together. Speech recognition is the ability of an operating system to convert spoken language into written text. Internal drivers (called SR engines) recognize these languages and are able to convert them to text. Windows XP speech recognition systems require speakers or other sound input devices to receive sound. Typically, the speaker should be a high quality device with an integrated noise filter. The speech recognition rate is directly related to the input quality. The recognition rate of inferior loudspeakers is very low, and some can't even be received. The Microsoft Speech Recognition Training Wizard (Voice Training Wizard) guides you through the required steps and recommends the best place to place the loudspeaker (tested by you for the best results). Using the Microsoft Speech Recognition Engine We can dictate text in any Microsoft Office XP program, Internet Explorer 5.0, and Outlook Express 5.0. Other software may eventually support the Microsoft Speech Recognition Engine, where you cannot dictate text in WordPad. Just as voice engines have specific languages, they may have specific regional requirements. For example, the "Microsoft English ASR Version 5 Engine" is for use by the United States, the United Kingdom, and Australia, and because of the different pronunciations, other people who do not speak American English are struggling. To use speech recognition, you need a high-quality close-range microphone and a sound card or USB port. You can use the Microphone Wizard to configure the location of your microphone. It is very important to train your speech recognition engine to be familiar with your voice. When you read the training text aloud, the engine finds a pattern that suits your speech to help it explain what you are saying. Training can create a voice profile for each speaker. Install the speech recognition system 1. Determine if the speech recognition engine is installed. 1. Click Start, point to Settings, click Control Panel, click Sound, Speech, and Audio Devices, and then click Voice. 2. If the Speech Recognition tab in Voice Attributes is available, the speech recognition engine is installed. Otherwise, the handwriting recognition engine is not yet installed. Second, install speech recognition from Microsoft Word 2002 1. Open Microsoft Word. 2. On the Tools menu, click Voice. Speech recognition is available in all Office programs and other programs that can activate speech recognition (for example, Microsoft Internet Explorer). Same as before: The speech recognition engine has the specified language. The first three available Microsoft speech engines are Simplified Chinese, US English, and Japanese. Speech Recognition Techniques After the Windows XP system is installed and working properly, it should be trained to adapt to the environment and speech style. On the Speech Recognition tab, click Training Profiles and use the Voice Training Wizard to train your system to recognize background noise (for example, fan sounds, noise from air conditioning equipment, or other office sounds) . It adapts to your speaking style, including stress, pronunciation and even idioms. Speech recognition is not an operation that is completely free of human intervention. If you use sound, mouse or keyboard in combination, you will get the best results. Moreover, a smooth and consistent voice quality will bring the best results. When talking to others, you can understand it through content and the environment, even by whispering, shouting or speaking speed. However, when speech recognition is broadcast in a more predictable manner, the best understanding of the words can be obtained. Too low or too soft a speech can make it difficult for a computer to recognize what you are saying; don't pause between words. Computers are more likely to recognize words than individual words. For example, a computer can have difficulty understanding such multiple words, such as "(pause) is" (pause) another (pause) sentence." Start talking in a quiet environment, so the computer will hear you Sounds, not other background sounds, should also use quality speakers. Please store the speaker in the same location, try not to move it during debugging. Train your computer to recognize your voice by reading the training text prepared in the Voice Training Wizard aloud. Other training will enhance the accuracy of speech recognition. When dictating, don't consider why you don't see words on the screen immediately. Continuous speech until all expression is completed. The computer will display the recognized text on the screen after the sound processing is completed. The pronunciation should be clear, but not separated by the syllable of each word. For example, the sound "e-nun-ci-ate" for each syllable is made, which makes it difficult for the computer to understand what you are saying.
