cURL

通过 cURL 进行声音复刻分为两步：先创建音色，再用该音色合成语音。

步骤一：创建音色

# 将 voice.mp3 替换为实际音频文件路径
# 以下为北京地域url，若使用新加坡地域的模型，需将url替换为：https://dashscope-intl.aliyuncs.com/api/v1/services/audio/tts/customization
# 新加坡和北京地域的API Key不同。获取API Key：https://help.aliyun.com/zh/model-studio/get-api-key

AUDIO_BASE64=$(base64 -i voice.mp3)

curl -X POST 'https://dashscope.aliyuncs.com/api/v1/services/audio/tts/customization' \
-H "Authorization: Bearer $DASHSCOPE_API_KEY" \
-H 'Content-Type: application/json' \
-d '{
    "model": "qwen-voice-enrollment",
    "input": {
        "action": "create",
        "target_model": "qwen3-tts-vc-2026-01-22",
        "preferred_name": "guanyu",
        "audio": {"data": "data:audio/mpeg;base64,'$AUDIO_BASE64'"}
    }
}'

步骤二：使用复刻音色合成语音

将上一步返回的voice值填入以下请求中。

# 将 YOUR_VOICE_ID 替换为上一步返回的 voice 值
# 以下为北京地域url，若使用新加坡地域的模型，需将url替换为：https://dashscope-intl.aliyuncs.com/api/v1/services/aigc/multimodal-generation/generation

curl -X POST 'https://dashscope.aliyuncs.com/api/v1/services/aigc/multimodal-generation/generation' \
-H "Authorization: Bearer $DASHSCOPE_API_KEY" \
-H 'Content-Type: application/json' \
-d '{
    "model": "qwen3-tts-vc-2026-01-22",
    "input": {
        "text": "今天天气怎么样？",
        "voice": "YOUR_VOICE_ID"
    }
}'
