微軟又一強大力作：語音識別，不喜歡打字的有福氣了

Microsoft Speech SDK 5.1（原程序帶的是英文引擎，另有中日文語言包，支持中文和日文輸入，現在好像還不支持別的語言吧）。

軟件簡介： Speech SDK 5.1 for Windows Speech SDK 5.1 for Windows applications The Microsoft Speech SDK 5.1 adds Automation support to the features of the previous version of the Speech SDK. You can now use the Win32 Speech API (SAPI) to develop speech applications with Microsoft Visual Basic and other development systems that use Automation. The SDK also includes freely distributable text-to-speech engines (in U.S. English and Simplified Chinese) and speech recognition engines (in U.S. English, Simplified Chinese, and Japanese). Speech SDK 5.1 replaces version 5.0, and Speech API (SAPI) version 5.1 is binary compatible with SAPI 5.0. If you are developing speech-enabled desktop applications for Windows, make sure to download this most recent version of the Speech SDK. 系配置和要求： Operating System Support and Requirements Supported Operating Systems Microsoft Windows XP Professional or Home Edition; all language versions. Microsoft Windows 2000 all versions; all language versions. Microsoft Windows Millennium Edition; all language versions. Microsoft Windows 98 all versions; all language versions. Microsoft Windows NT 4.0 Workstation or Server, Service Pack 6a, English, Japanese, or Simplified Chinese versions. Windows 95 or earlier is not supported. Software Requirements Microsoft Internet Explorer 5.0 or later version. Users of Windows NT 4.0 require Microsoft Internet Explorer 5.5 or later. Download the latest version of Microsoft Internet Explorer. Microsoft Visual C++ 6.0, Service Pack 3 or later version is needed to run the SAPI 5 SDK samples. In general, any 32-bit C compiler will work for writing SAPI applications. Visual Basic 6.0 is needed to write applications incorporating SAPI automation, or for compiling the Visual Basic sample code. Since SAPI supports COM automation, other languages and compilers may be used with SAPI automation provided it supports OLE automation. Microsoft Visual Studio .NET is needed to compile the C# examples. The Platform SDK is generally not needed although some samples and functionality may require it. See the specific samples for confirmation. If required, the Platform SDK may be downloaded from the Microsoft Platform SDK site. Hardware Requirements A Pentium II or Pentium II-equivalent or later processor at 233 MHz; 128 megabytes (MB) of RAM is recommended. A microphone or some other sound input device to receive the sound is required for speech recognition (SR). In general, the microphone should be a high quality device with built-in noise filters. The speech recognition rate is directly related to the quality of the input. The recognition rate will be significantly lower or perhaps even unacceptable with a poor microphone. Not all sound cards or sound devices are supported by SAPI 5, even if the operating system supports them otherwise.
