使用实时语音合成

前提条件

• 确保已按照配置CPP环境（Windows）配置完毕。
• 请参考SDK（websocket）获取最新版本SDK包。

初始化Client

初始化RttsClient，其参数包括AuthInfo

请求参数

请求类为RttsRequest，详见表 RttsRequest。

通过set方法可以设置具体参数，详见表 RttsRequest设置参数

示例代码

如下示例仅供参考，最新代码请前往SDK（websocket）章节获取并运行。

#include "IoUtil.h"
#include "RttsClient.h"
#include "RttsRequest.h"

void OnRttsConnect() {
	std::cout << "now rtts client Connect success" << std::endl;
}

void OnRttsStart(std::string text) {
	std::cout << "now rtts client receive start response: " << text << std::endl;
}

void OnRttsEnd(std::string text) {
	std::cout << "now rtts client  receive end response: " << text << std::endl;
}


void OnRttsClose() {
	std::cout << "now rtts client receive Close" << std::endl;
}

void OnRttsError(std::string text) {
	std::cout << "now  rtts client receive error: " << text << std::endl;
}


void OnRttsBinary(std::string binaryData) {
	// data content can be avaliable by data() method, data length can be avaliable by size() method
	// const char* data = binaryData.data();
	// int dataLength = binaryData.size();
	std::cout << "now rtts client receive binary data " << binaryData.size() << std::endl;
}

	// 1. config parameter
	// 1.1 init authInfo
        // 认证用的ak和sk硬编码到代码中或者明文存储都有很大的安全风险，建议在配置文件或者环境变量中密文存放，使用时解密，确保安全；
       // 本示例以ak和sk保存在环境变量中来实现身份验证为例，运行本示例前请先在本地环境中设置环境变量HUAWEICLOUD_SDK_AK和HUAWEICLOUD_SDK_SK
	std::string ak = GetEnv("HUAWEICLOUD_SDK_AK");
	std::string sk = GetEnv("HUAWEICLOUD_SDK_SK");
	std::string region = "";
	std::string projectId = "";

	// 1.2 config Connect parameter
	HttpConfig httpConfig;
	httpConfig.SetReadTimeout(20000);
	httpConfig.SetConnectTimeout(20000);

	websocketServicePtr->SetOnConnectFunc(OnRttsConnect);       // Connect success callback
	websocketServicePtr->SetOnStartFunc(OnRttsStart);				// receive start response callback

	websocketServicePtr->SetOnErrorFunc(OnRttsError);           // receive error callback
	websocketServicePtr->SetOnBinaryFunc(OnRttsBinary);     // receive binary callback

	// 1.3 option, use RttsListener, which can save file; You can edit RttsListener.h to finish your own business
	//WebsocketService::ptr websocketServicePtr = websocketpp::lib::make_shared<WebsocketService>();
	//RttsListener rttsListener;
	//rttsListener.SetSaved(true);
	//rttsListener.SetFilePath("d:/test5.pcm");
        //websocketServicePtr->SetRttsListener(rttsListener);


	// 1.4 config request parameter
	std::string text = AnsiToUtf8("华为致力于把数字世界带入每个人每个家庭每个组织，构建万物互联的智能世界。");
	RttsRequest request(text);
	request.SetAudioFormat("pcm");
	request.SetVolume(50);
	request.SetSpeed(0);
	request.SetPitch(0);
	request.SetSampleRate("8000");
	request.SetAudioProperty("chinese_xiaoyan_common");


	// 2. init client
	RttsClient* rttsClient = new RttsClient(authInfo, websocketServicePtr, httpConfig);

	// 3. send request
	rttsClient->Synthesis(request);
	// wait for save file, if setSaved false in rttsListener or don't use rttsListener, it can be removed.
	std::this_thread::sleep_for(std::chrono::milliseconds(2000));
	delete rttsClient;
