科大讯飞语音识别功能还是很强大的，之前一直在做移动端的语音识别功能，一直没弄过Windows平台的，在网上找了很多别人写的功能，然后自己整理了一下。 其实就是把讯飞的window平台的C/C++接口转换成C#能调用的接口，利用DllImport将封装在C/C++里的部分用到的函数转换为C#可以直接调用的函数 首先创建一个MscDLL类，将C/C++的接口转换为C#，然后把C语言头文件msp_errors.h中的错误以及各种状态封装到该类中。下面是代码。文章源自大腿Plus-https://www.shijunzh.com/archives/1229

QISRAudioWrite（）；
功能：写入本次识别的音频
参数1：之前已经得到的sessionID
参数2：音频数据缓冲区起始地址
参数3：音频数据长度,单位字节。
参数4：用来告知MSC音频发送是否完成
MSP_AUDIO_SAMPLE_FIRST = 1 第一块音频
MSP_AUDIO_SAMPLE_CONTINUE = 2 还有后继音频
MSP_AUDIO_SAMPLE_LAST = 4 最后一块音频
参数5：端点检测（End-point detected）器所处的状态
MSP_EP_LOOKING_FOR_SPEECH = 0 还没有检测到音频的前端点。
MSP_EP_IN_SPEECH = 1 已经检测到了音频前端点，正在进行正常的音频处理。
MSP_EP_AFTER_SPEECH = 3 检测到音频的后端点，后继的音频会被MSC忽略。
MSP_EP_TIMEOUT = 4 超时。
MSP_EP_ERROR = 5 出现错误。
MSP_EP_MAX_SPEECH = 6 音频过大。
参数6：识别器返回的状态，提醒用户及时开始\停止获取识别结果
MSP_REC_STATUS_SUCCESS = 0 识别成功，此时用户可以调用QISRGetResult来获取（部分）结果。
MSP_REC_STATUS_NO_MATCH = 1 识别结束，没有识别结果。
MSP_REC_STATUS_INCOMPLETE = 2 正在识别中。
MSP_REC_STATUS_COMPLETE = 5 识别结束。
返回值：函数调用成功则其值为MSP_SUCCESS，否则返回错误代码。
本接口需不断调用，直到音频全部写入为止。上传音频时，需更新audioStatus的值。具体来说:
当写入首块音频时,将audioStatus置为MSP_AUDIO_SAMPLE_FIRST
当写入最后一块音频时,将audioStatus置为MSP_AUDIO_SAMPLE_LAST
其余情况下,将audioStatus置为MSP_AUDIO_SAMPLE_CONTINUE
同时，需定时检查两个变量：epStatus和rsltStatus。具体来说:
当epStatus显示已检测到后端点时，MSC已不再接收音频，应及时停止音频写入
当rsltStatus显示有识别结果返回时，即可从MSC缓存中获取结果

最后将SDK包中的三个文件夹导入到新建的工程中。每个应用对应一个appid，每个应用的sdk都要和appid对应上。我这个只是测试用的，想要用到实际项目中要在讯飞上创建应用下载sdk。下载链接: https://pan.baidu.com/s/1Bf8L7uuuUXPwG9QyBZZGjQ 提取码: cj9m文章源自大腿Plus-https://www.shijunzh.com/archives/1229
