歌声合成服务可广泛应用于音视频创意制作、影音娱乐、音乐教育、虚拟偶像等领域。例如，在音乐创作或短视频创意编辑时，歌声合成服务可以助力用户自由创作合成歌曲，使创作更加丰富多彩。在虚拟偶像领域，通过歌声合成，可以让虚拟人拥有特定音色歌唱能力，使其形象更生动。在音乐游戏或者歌唱教育中，歌声合成可以迅速生成标准参考声音，提高音频制作效率节省人力成本。
歌声合成效果
听到了歌声合成媲美真人的歌唱效果，是否迫不及待想上手使用了呢，以下是歌声合成的具体集成方法。快来亲自集成试试吧！
1.开发准备
1.1注册成为开发者
在开发应用前需要在华为开发者联盟网站上注册成为开发者并完成实名认证，具体方法请参见帐号注册认证。
1.2创建项目及应用
参见创建项目，然后在项目下创建应用完成应用的创建，特殊配置如下：
选择平台：选择“Web”。
1.3打开相关服务
使用Audio Editor Kit服务需要您在AppGallery Connect上打开Audio Editor Kit服务开关，具体操作步骤请参见打开服务开关。
2.歌声合成功能集成
2.1同步接口（流式）
2.1.1获取access_token鉴权信息
使用开发者联盟界面获得的客户端ID以及对应密钥，发送HTTPS POST请求，获取查询access_token。获取方式请参见客户端模式（Client Credentials）。
2.1.2根据access_token调用同步接口（流式）
通过以上步骤获取的access_token信息，发送HTTPS POST调用同步接口（流式）。
示例代码（Java）如下所示：
其中requestUrl = "https://audioeditor-api-drcn.cloud.huawei.com/v1/audioeditor/gateway/ai/ttsing/sync"。
/**
* 调用同步接口（流式）
* @param accessToken 根据clientId和密钥获取的token
* @throws Exception IO异常
*/
private static void syncTask(String accessToken) throws Exception {
// 设置请求header
PostMethod postMethod = new PostMethod(requestUrl);
postMethod.setRequestHeader("Content-Type","application/json;charset=utf-8");
postMethod.setRequestHeader("X-Request-ID","9af1aeda-531b-407a-80b4-65b40ef77bd6");
postMethod.setRequestHeader("X-Package-Name","com.huawei.demo");
postMethod.setRequestHeader("X-Country-Code","cn");
postMethod.setRequestHeader("HMS-APPLICATION-ID","123456");
postMethod.setRequestHeader("certFingerprint","xxxxx");
postMethod.setRequestHeader("Authorization","Bearer " + accessToken);
// 设置请求body
Map<String, Object> bodyMap = new HashMap<>();
Map<String, Object> dataMap = new HashMap<>();
Map<String, Object> configMap = new HashMap<>();
// filePath是MusicXML文件路径（含文件名、后缀）
String lyricFilePath = "filePath";
dataMap.put("lyric", FileUtils.readFileToString(new File(lyricFilePath), "UTF-8"));
dataMap.put("language", "chinese");
configMap.put("type", 1);
configMap.put("outputEncoderFormat", 0);
bodyMap.put("data", dataMap);
bodyMap.put("config", configMap);
RequestEntity requestEntity = new StringRequestEntity(JSONObject.toJSONString(bodyMap),"application/json" ,"UTF-8");
postMethod.setRequestEntity(requestEntity);
HttpClient httpClient = new HttpClient();
int ret = httpClient.executeMethod(postMethod);
if (ret == 200) {
Header responseHeader = postMethod.getResponseHeader("content-type");
if ("application/octet-stream".equals(responseHeader.getValue())) {
InputStream rpsContent = postMethod.getResponseBodyAsStream();
// filePath是要保存文件的路径（含文件名、后缀）
String filePath = "filePath";
FileUtils.copyInputStreamToFile(rpsContent, new File(filePath));
} else {
String errorString = postMethod.getResponseBodyAsString();
System.out.println(errorString);
}
} else {
System.out.println("callApi failed: ret =" + ret + " rsp=" + postMethod.getResponseBodyAsString());
}
}
2.2异步接口
2.2.1创建异步任务
通过access_token信息，发送HTTPS POST创建歌声合成异步任务。
/**
* 调用创建异步任务接口
* @param accessToken 根据clientId和密钥获取的token
* @throws Exception IO异常

// 设置请求header
PostMethod postMethod = new PostMethod(requestUrl);
postMethod.setRequestHeader("Content-Type","application/json;charset=utf-8");
postMethod.setRequestHeader("X-Request-ID","9af1aeda-531b-407a-80b4-65b40ef77bd6");
postMethod.setRequestHeader("X-Package-Name","com.huawei.demo");
postMethod.setRequestHeader("X-Country-Code","cn");
postMethod.setRequestHeader("HMS-APPLICATION-ID","123456");
postMethod.setRequestHeader("certFingerprint","xxxxx");
postMethod.setRequestHeader("Authorization","Bearer " + accessToken);
// 设置请求body
Map<String, Object> bodyMap = new HashMap<>();
Map<String, Object> dataMap = new HashMap<>();
