ttsGetAudLibInfoList
　　得到指定语言的所有发音人信息列表。



语法：
　　int ttsGetAudLibInfoList (
　　　int nLanguage,
　　　SPEAKERINFO* pSpeakerInfo
　　);



参数
nLanguage 语言种类，0：普通话，1：粤语 2：英语
pSpeakerInfo 指向全体发音人信息结构体的指针,SPEAKERINFO结构体参见注释



返回值：
　　成功返回0，失败返回其它。



注释：
　　 typedef struct
　{
　　 int m_nSpeakerNum;
　　 char m_szSpeakerDesc[MAX_SPEAKER_NUM][MAX_SPEAKER_DESC_NUM];
　　 char m_szSpeakerName[MAX_SPEAKER_NUM][MAX_SPEAKER_PATH_NUM];
　}SPEAKERINFO;
　　自上至下依次是发音人数量,发音人的描述,以及发音人的路径.

尤其是这个SPEAKERINFO如何改写成vb的自定义数据类型，请懂C语言的大神看看，帮帮忙

tpye SPEAKERINFO
    SpeakerNum as long '不用前缀了吧！
    SpeakerDesc(1 to MAX_SPEAKER_NUM,1 to MAX_SPEAKER_DESC_NUM) as byte
    SpeakerName(1 to MAX_SPEAKER_NUM,1 to MAX_SPEAKER_PATH_NUM) as byte
end type
自己调试转字符看看对不对吧。话说咱怀疑它会出错。

我感觉这个定义用 STRING 更好。

tpye SPEAKERINFO
    SpeakerNum as long
    SpeakerDesc(1 to MAX_SPEAKER_DESC_NUM） as string *  MAX_SPEAKER_NUM
    SpeakerName(1 to MAX_SPEAKER_PATH_NUM as string * MAX_SPEAKER_NUM
end type

感谢上面二位大神，二位的代码运行后都要求 to 后面为常数。改成这样可以通过：

Type SPEAKERINFO
    SpeakerNum As Long
    SpeakerDesc(1 To 10) As String * MAX_SPEAKER_NUM
    SpeakerName(1 To 10) As String * MAX_SPEAKER_NUM
End Type

但又出现错误49,DLL调用约定错误，我已经凌乱了

这是慧声语音的SkyVoice.dll，无法引入vb，所以想动态调用。
上面的内容是慧声语音提供的一个.h头文件中的，我想根据这个头文件改写成vb声明。

这是慧声语音SDK下载地址：
http://www.
这个语音引擎非常好，二个语音库加起来才30M左右，却几乎可以达到讯飞语音的流畅效果。
我想用它的SDK作二次开发，但是卡在了dll函数声明这块，不知哪位C语言达人可以试一下。

最近因为工作需要，我要合成一批中文语音文件，我比较了多种语音，最后选中了慧声语音。由于慧声语音工作室开发的朗声语音操作不方便而且不能输出声音文件，所以我写了一个辅助工具，顺利完成了任务，而且效果非常好。
这是我用易语言写的一个朗声语音辅助工具，很好用的：
http://www.



如果能引用它的SDK ,就可以随心所欲地实现自己的想法了。可惜我的C语言只够写个hello world.

回四楼：

#define MAX_SPEAKER_NUM        10
#define MAX_SPEAKER_DESC    256
#define MAX_SPEAKER_PATH    256

根据你的 头文件。
这三个 符号 需要定义为 常量。定义到模块里。
public const MAX_SPEAKER_NUM =10
public const MAX_SPEAKER_DESC =256
public const MAX_SPEAKER_PATH =256
