【转】SAPI 包含sphelper.h编译错误解决方案

在使用Microsoft Speech SDK 5.1开发语音识别程序时，包含了头文件“sphelper.h”和库文件“sapi.lib”。编译时出错：

1>c:\program files\microsoft speech sdk 5.1\include\sphelper.h(769) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

1>c:\program files\microsoft speech sdk 5.1\include\sphelper.h(1419) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
1>c:\program files\microsoft speech sdk 5.1\include\sphelper.h(2373) : error C2065: 'psz' : undeclared identifier

1>c:\program files\microsoft speech sdk 5.1\include\sphelper.h(2559) : error C2440: 'initializing' : cannot convert from 'CSpDynamicString' to 'SPPHONEID *'
1>        No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
1>c:\program files\microsoft speech sdk 5.1\include\sphelper.h(2633) : error C2664: 'wcslen' : cannot convert parameter 1 from 'SPPHONEID *' to 'const wchar_t *'
1>        Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

 

搜索了一圈，根据大家的经验汇总，应该是Speech代码编写时间太早，语法不严密。而VS2005对于语法检查非常严格，导致编译无法通过。修改头文件中的以下行即可正常编译：

Ln 769

    const ulLenVendorPreferred = wcslen(pszVendorPreferred);
    const unsigned long ulLenVendorPreferred = wcslen(pszVendorPreferred);

 

Ln 1418

    static CoMemCopyWFEX(const WAVEFORMATEX * pSrc, WAVEFORMATEX ** ppCoMemWFEX)

    static HRESULT CoMemCopyWFEX(const WAVEFORMATEX * pSrc, WAVEFORMATEX ** ppCoMemWFEX)

Ln 2372

    for (const WCHAR * psz = (const WCHAR *)lParam; *psz; psz++) {}

    const WCHAR * psz; for (psz = (const WCHAR *)lParam; *psz; psz++) {}

Ln 2559

    SPPHONEID* pphoneId = dsPhoneId;

    SPPHONEID* pphoneId = (SPPHONEID*)((WCHAR *)dsPhoneId);

Ln 2633
    pphoneId += wcslen(pphoneId) + 1;
    pphoneId += wcslen((const wchar_t *)pphoneId) + 1;

好了，编译通过，下面可以正式编写程序逻辑了。
