怎么用C语音说话，读汉字，读英文都行。

我想写一个C语言小程序（就是黑框框的那种），我想让它把我的句子读出来,比如早上好之类的。

google里面搜索microsoft tts或者text to speach

这里有一个VB程序的，

 set objTTS = CreateObject("sapi.spvoice")
objTTS.speak("你好呀。")

用记事本保存，然后把记事本文本文件后缀名改为vbs

用C调用Google 语音的API即可

VS下根据官方示例简单改变做的小例子

#define _ATL_APARTMENT_THREADED
//#include <afx.h>
//extern CComModule _Module;
#include <stdio.h>
#include <atlbase.h>
#include <atlcom.h>
#include <sapi.h>

int main(int argc, char* argv[])
{
    ISpVoice * pVoice = NULL;

    if (FAILED(::CoInitialize(NULL)))
        return FALSE;

    HRESULT hr = CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpVoice, (void **)&pVoice);
    if (SUCCEEDED(hr))
    {
        FILE* file;
        file = fopen("C:\\Users\\zhouchong\\Desktop\\txt\\auotomedian.txt", "r");
        if (file == NULL)
        {
            return 0;
        }
        else
        {
            char buff[1024];
            USES_CONVERSION;
            while (fgets(buff, 1024, file) != NULL)
            {
            //  hr = pVoice->Speak(L"Hello world", 0, NULL);
                wchar_t* test12 = A2W(buff);
                hr = pVoice->Speak(test12, 0, NULL);

            }
            pVoice->Release();
            pVoice = NULL;
        }
        ::CoUninitialize();
    }

    return TRUE;
}

推荐讯飞的平台做这个，可以做翻译。如果需要从图像抓取还需要OCR

楼上的就可行，或者你找百度的文字转语音接口服务也可以实现

从头写肯定不现实，可以在网上找现成的库，你来调用，也可以找一些免费的服务

如果想说文字的话，可能需要调用语音API，但是比较麻烦，就像楼上说的用VBS可能更适合你。ps:如果想用C语言编写一首歌的话不妨尝试Beep函数
虽然艺术性不强，但还是蛮有趣的，贴一段生日歌代码
