VS2005下调用MS Speech API 5.1, 在添加“sphelper.h”头文件出现的问题，及解决方法

在利用微软的SAPI开发语音合成程序，当添加头文件#include "sphelper.h"时出现了类似下面的error和warning：

一开始，始终觉得是自己程序的问题，可找了半天还是没有找到原因，在网上搜索了一下，发现有不少网友曾遇到此类问题，可始终没有找到很好的解决办法。有位网友提出在vc6下下做个dll，然后放到vs2005下去调用，此方法不失为一个好方法。可还是不甘心，觉得太麻烦！继续搜索，终于在MS的论坛上发现一篇帖子是针对这个问题的，其中有位名叫Pete Baron 的网友提出了解决办法，个人觉得此方法比较方便实用，在此提供，以方便其他好友参考：

I'm not sure if these steps 'fix' the errors, but they permit the code to compile (honestly, I couldn't be bothered to try and decode the awful code in that file so I just used best-guess to what was intended in each case).  I didn't test speech-to-text, but the text-to-speech will definitely work correctly.

1) line 2560
    SPPHONEID* pphoneId = (SPPHONEID*)((WCHAR *)dsPhoneId);

2) line 2634
    pphoneId += wcslen((const wchar_t *)pphoneId) + 1;

3) line 2372 and 2373
        const WCHAR *psz;
        for (psz = (const WCHAR *)lParam; *psz; psz++) {}

4) add to the top of the file to prevent all the other errors...
#pragma warning( disable : 4430 )

I also added another line to prevent a stream of 'deprecated function' warnings
#pragma warning( disable : 4996 )
