用python语言基于阿里达摩院的声音克隆API，写一个克隆真人声音的python程序

```python
import requests
import base64
import json
import os

# 设置API参数
api_key = "你的阿里达摩院API密钥"
secret_key = "你的阿里达摩院API密钥"
session_token = "你的阿里达摩院API会话令牌"
voice_id = "真人声音的ID"
text = "需要克隆的文本"

# 获取访问令牌
def get_access_token(api_key, secret_key):
url = "https://open.alipay.com/oauth2/system/token"
params = {
"grant_type": "client_credentials",
"client_id": api_key,
"client_secret": secret_key
}
response = requests.get(url, params=params)
data = json.loads(response.text)
return data["access_token"]

# 调用声音克隆API
def clone_voice(access_token, session_token, voice_id, text):
url = f"https://tsn.aliyuncs.com/acs/v1/tts/clone?voice_id={voice_id}&text={base64.b64encode(text.encode('utf-8')).decode('utf-8')}"
headers = {
"Authorization": f"Bearer {session_token}",
"Content-Type": "application/json"
}
response = requests.post(url, headers=headers, data={"access_token": access_token})
return response.content

# 保存克隆后的音频文件
def save_audio(data, file_name):
with open(file_name, "wb") as f:
f.write(data)

if __name__ == "__main__":
access_token = get_access_token(api_key, secret_key)
session_token = get_access_token(api_key, secret_key)
cloned_data = clone_voice(access_token, session_token, voice_id, text)
save_audio(cloned_data, "cloned_voice.mp3")
```
