HMS Core音频编辑服务（Audio Editor Kit）6.6.0版本上线，新增歌声合成能力。通过歌词和曲调，联合不同的曲风让机器也能生成真实度极高的歌声。反对字级别输出歌词进行音素转换，生成对应歌词的歌声，可灵便调整音高、滑音、呼吸音、颤音等细节参数，让歌声更实在。
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、虚构偶像等畛域。例如，在音乐创作或短视频创意编辑时，歌声合成服务能够助力用户自在创作合成歌曲，使创作更加丰富多彩。在虚构偶像畛域，通过歌声合成，能够让虚拟人领有特定音色歌唱能力，使其形象更活泼。在音乐游戏或者歌唱教育中，歌声合成能够迅速生成规范参考声音，进步音频制作效率节俭人力老本。

抉择平台：抉择“Web”。
1.3关上相干服务
应用Audio Editor Kit服务须要您在AppGallery Connect上关上Audio Editor Kit服务开关，具体操作步骤请参见关上服务开关。
2.歌声合成性能集成
2.1同步接口（流式）
2.1.1获取access_token鉴权信息
应用开发者联盟界面取得的客户端ID以及对应密钥，发送HTTPS POST申请，获取查问access_token。获取形式请参见客户端模式（Client Credentials）。
2.1.2依据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 依据clientId和密钥获取的token * @throws Exception IO异样 */ private static void syncTask(String accessToken) throws Exception { // 设置申请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); // 设置申请body Map<String, Object> bodyMap = new HashMap<>(); Map<String, Object> dataMap = new HashMap<>(); Map<String, Object> configMap = new HashMap<>(); // filePath是MusicXML文件门路（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是要保留文件的门路（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创立异步工作
通过access_token信息，发送HTTPS POST创立歌声合成异步工作。
/** * 调用创立异步工作接口 * @param accessToken 依据clientId和密钥获取的token * @throws Exception IO异样 */ private static void creatAsyncTask(String accessToken) throws Exception { // 设置申请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); // 设置申请body Map<String, Object> bodyMap = new HashMap<>(); Map<String, Object> dataMap = new HashMap<>(); Map<String, Object> configMap = new HashMap<>(); // filePath是MusicXML文件门路（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); String rpsContent = postMethod.getResponseBodyAsString(); if (ret == 200) { System.out.println(rpsContent); } else { System.out.println("callApi failed: ret =" + ret + " rsp=" + rpsContent); } }2.2.2查问异步工作状态
通过access_token信息，发送HTTPS POST查问歌声合成异步工作状态。
/** * 调用查问异步工作状态接口 * @param accessToken 依据clientId和密钥获取的token * @throws Exception IO异样 */ private static void queryAsyncTaskInfo(String accessToken) throws Exception { // 设置申请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); // 设置申请body Map<String, Object> bodyMap = new HashMap<>(); // taskId对应的值是创立异步工作时返回的工作ID（taskId） bodyMap.put("taskId", "taskId"); RequestEntity requestEntity = new StringRequestEntity(JSONObject.toJSONString(bodyMap),"application/json" ,"UTF-8"); postMethod.setRequestEntity(requestEntity); HttpClient httpClient = new HttpClient(); int ret = httpClient.executeMethod(postMethod); String rpsContent = postMethod.getResponseBodyAsString(); if (ret == 200) { System.out.println(rpsContent); } else { System.out.println("callApi failed: ret =" + ret + " rsp=" + rpsContent); } }2.2.3勾销异步工作
通过access_token信息，发送HTTPS POST勾销异步工作。
/** * 调用勾销异步工作接口 * @param accessToken 依据clientId和密钥获取的token * @throws Exception IO异样 */ private static void cancelAsuncTask(String accessToken) throws Exception { // 设置申请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); // 设置申请body Map<String, Object> bodyMap = new HashMap<>(); // taskId对应的值是创立异步工作时返回的工作ID（taskId） bodyMap.put("taskId", "taskId"); RequestEntity requestEntity = new StringRequestEntity(JSONObject.toJSONString(bodyMap),"application/json" ,"UTF-8"); postMethod.setRequestEntity(requestEntity); HttpClient httpClient = new HttpClient(); int ret = httpClient.executeMethod(postMethod); String rpsContent = postMethod.getResponseBodyAsString(); if (ret == 200) { System.out.println(rpsContent); } else { System.out.println("callApi failed: ret =" + ret + " rsp=" + rpsContent); } }除了歌声合成能力，音频编辑服务还提供音频根底编辑、AI配音伴奏提取、空间渲染、变声降噪等丰盛的音频解决能力，为寰球开发者提供性能优异、简略易用、开放性强的接口，帮忙开发者轻松高效构建利用音频编辑能力。
