Java SDK - 千问AI平台

通过 DashScope Java SDK 的 VoiceEnrollmentService 类调用 Qwen-Audio-TTS/CosyVoice 声音复刻。该 SDK 仅覆盖声音复刻功能，CosyVoice 声音设计以及所有 Qwen 声音复刻/设计请使用 HTTP API。 用户指南：声音复刻。

前提条件

Service URL

创建服务前设置 base URL：

import com.alibaba.dashscope.utils.Constants;

Constants.baseHttpApiUrl = "https://dashscope.aliyuncs.com/api/v1";

VoiceEnrollmentService 类

包路径：com.alibaba.dashscope.audio.ttsv2.enrollment.VoiceEnrollmentService 管理 Qwen-Audio-TTS/CosyVoice 克隆音色的完整生命周期（创建、列表、查询、更新、删除）。

构造方法

public VoiceEnrollmentService(String apiKey)

参数	类型	说明
apiKey	String	DashScope API Key。

createVoice()

从音频创建克隆音色。

public Voice createVoice(String targetModel, String prefix, String url,
                         VoiceEnrollmentParam customParam)
    throws NoApiKeyException, InputRequiredException

参数	类型	必选	说明
targetModel	String	是	克隆音色绑定的语音合成模型。后续合成调用的 model 必须与此一致。
prefix	String	是	音色名称前缀，仅限字母和数字，最长 10 个字符。
url	String	是	用于克隆的音频文件 URL，必须可公开访问。
customParam	VoiceEnrollmentParam	否	自定义参数，可通过 `parameter()` 方法指定 `language_hints`、`max_prompt_audio_length` 等。详见 VoiceEnrollmentParam。

返回值：Voice 对象，调用 getVoiceId() 获取音色 ID。

显示示例

import com.alibaba.dashscope.audio.ttsv2.enrollment.VoiceEnrollmentService;
import com.alibaba.dashscope.audio.ttsv2.enrollment.Voice;
import com.alibaba.dashscope.utils.Constants;

Constants.baseHttpApiUrl = "https://dashscope.aliyuncs.com/api/v1";

VoiceEnrollmentService service = new VoiceEnrollmentService(apiKey);

Voice voice = service.createVoice(
  "qwen-audio-3.0-tts-flash",
  "myvoice",
  "https://your-audio-url.wav",
  null
);

System.out.println("Created voice: " + voice.getVoiceId());

listVoice()

列出克隆音色，支持前缀过滤和分页。

public Voice[] listVoice(String prefix, int pageIndex, int pageSize)
    throws NoApiKeyException, InputRequiredException

参数	类型	必选	说明
prefix	String	否	按名称前缀过滤。
pageIndex	int	否	页码，从 0 开始。
pageSize	int	否	每页条数。

返回值：Voice[] 音色对象数组。

  System.out.println("Voice: " + v.getVoiceId());
}

queryVoice()

查询指定克隆音色的详细信息。

public Voice queryVoice(String voiceId)
    throws NoApiKeyException, InputRequiredException

VoiceEnrollmentParam 类

包路径：com.alibaba.dashscope.audio.ttsv2.enrollment.VoiceEnrollmentParam 使用 Builder 模式构造 createVoice() 和 updateVoice() 的可选参数。

Builder 方法	类型	说明
model(String)	String	声音复刻模型，固定为 `voice-enrollment`。
parameter(String, Object)	Object	设置自定义参数，如 `parameter("language_hints", Arrays.asList("zh"))`、`parameter("max_prompt_audio_length", 10.0f)`、`parameter("enable_preprocess", false)`、`parameter("enable_volume_normalization", "false")`。

enable_preprocess

参数	类型	必选	说明
enable_preprocess	boolean	否	是否启用音频预处理（降噪、增强、音量归一化）。有噪音的音频建议开启，干净音频建议关闭。默认：`false`。

enable_volume_normalization

参数	类型	必选	说明
enable_volume_normalization	String	否	是否对用于声音复刻的样本音频进行音量归一化。取值为 `"true"` 或 `"false"`。开启后，使用所创建音色合成的音频，其音量可能与关闭该参数时创建的音色不同。默认：`"false"`。
