腾讯云---语音合成---一段文本合成语音
您好!对于腾讯云的语音合成服务,您可以使用其提供的 API 进行一段文本合成语音。具体步骤如下:
1. 登录腾讯云控制台,并创建一个语音合成应用。
2. 获取 API 密钥,包括 SecretId 和 SecretKey。
3. 在您的应用中,使用腾讯云提供的 API 进行调用。可以使用 HTTP POST 请求方式,将待合成的文本作为参数传递给 API,并将返回结果保存为音频文件。
以下是一个使用 Python 调用腾讯云语音合成 API 的示例代码:
```python
import requests
import hashlib
import time
import random
secret_id = 'YOUR_SECRET_ID'
secret_key = 'YOUR_SECRET_KEY'
app_id = 'YOUR_APP_ID'
text = '待合成的文本'
def get_signature(app_id, secret_id, secret_key, expired):
now = int(time.time())
rdm = random.randint(0, 999999999)
plain_text = 'a={}&b={}&k={}&e={}&t={}&r={}&u={}&f={}&s={}'.format(
app_id, 'tts', secret_id, expired, now, rdm, '', '0', '1')
m = hashlib.md5()
m.update(plain_text.encode())
signature = m.hexdigest()
return signature
def generate_tts(text):
url = 'https://tts.cloud.tencent.com/stream'
expired = int(time.time()) + 86400
signature = get_signature(app_id, secret_id, secret_key, expired)
payload = {
'a': app_id,
'b': 'tts',
'k': secret_id,
'e': str(expired),
't': str(int(time.time())),
'r': str(random.randint(0, 999999999)),
'u': '',
'f': '0',
's': '1',
'tex': text.encode('utf-8'),
'sign': signature
}
response = requests.post(url, data=payload)
if response.status_code == 200:
with open('output.mp3', 'wb') as f:
f.write(response.content)
print('语音合成成功!音频文件已保存为 output.mp3')
else:
print('语音合成失败!错误信息:{}'.format(response.text))
generate_tts(text)
```
请将示例代码中的 `YOUR_SECRET_ID`、`YOUR_SECRET_KEY`、`YOUR_APP_ID` 和 `待合成的文本` 替换为您自己的实际信息。执行该代码后,将会在当前目录下生成一个名为 `output.mp3` 的音频文件,即为合成后的语音。
希望能对您有所帮助!如有任何问题,请随时提问。
