讯飞C/C++语音合成基础篇

首先到讯飞上注册一个帐号(感觉讯飞官网和阿里云官网的差不多)

随后创建一个新应用(Windows平台下)

最后我们要的是Appid如下图所示

下面是讯飞SDK(含说明文档)下载地址：

因为此程序涉及WAV语音知识，未了解WAV的朋友请百度补充，或者在下面这个链接初略的学习下

下面先来认识下几个API(从文档提取出来)

1.int MSPAPI MSPLogin (const char *usr, const char *pwd, const char *params) //初始化msc，用户登录。

usr[in] 此参数保留，传入NULL即可。
pwd[in] 此参数保留，传入NULL即可。

官方例子

const char* usr = NULL; const char* pwd = NULL; const char* lgi_param = "appid = ********"; int ret = MSPLogin(usr, pwd, lgi_param); if( MSP_SUCCESS != ret ) {printf( "MSPLogin failed, error code is: %d", ret ); }

2.const char *MSPAPI QTTSSessionBegin (const char *params, int *errorCode) //开始一次语音合成，分配语音合成资源。

(信息有点多,参数具体见文档qtts.h 文件参考)

下面是官方例子

const char * ssb_param = "voice_name = xiaoyan, aue = speex-wb;7, sample_rate = 16000, speed = 50, volume = 50, pitch = 50, rdn = 2"; int ret = -1; const char * sessionID = QTTSSessionBegin( ssb_param, &ret ); if( MSP_SUCCESS != ret ) {printf( “QTTSSessionBegin failed, error code is: %d”, ret ); }

3.const void *MSPAPI QTTSAudioGet (const char *sessionID, unsigned int *audioLen, int *synthStatus, int *errorCode) //获取合成音频
(信息有点多,参数具体见文档qtts.h 文件参考)

例子

FILE* fp = fopen("tts.pcm", "wb"); while (1) {const void * data = QTTSAudioGet(sessionID, &audio_len, &synth_status, &ret);if (NULL != data){fwrite(data, audio_len, 1, fp);}if (MSP_TTS_FLAG_DATA_END == synth_status || MSP_SUCCESS != ret){break;} } fclose(fp);

4.int MSPAPI QTTSSessionEnd (const char *sessionID, const char *hints) //结束本次语音合成。

int ret = QTTSSessionEnd ( sessionID, “normal end” ); if( MSP_SUCCESS != ret ) {printf( “QTTSSessionEnd failed, error code is: %d”, ret ); }


下面是完整项目的代码:

几个个文件1.stdafx.h。2.targetver.h。3.QTTSDemo.cpp。4.stdafx.cpp。

除了QTTSDemo.cpp外，其他文件都是vs2013创建控制台程序自带的，在此只给出QTTSDemo.cpp代码

但注意在stdafx.h中加入#define _CRT_SECURE_NO_WARNINGS
