Alibaba Cloud Model Studio:Qwen-TTS non-real-time speech synthesis API reference

Python

The SpeechSynthesizer interface in the DashScope Python SDK is now unified under MultiModalConversation. To switch to the new interface, simply replace the name — all other parameters are fully compatible.

# DashScope SDK version 1.24.5 or later required

import dashscope
# Singapore region
dashscope.base_http_api_url = 'https://dashscope-intl.aliyuncs.com/api/v1'

It's truly beautiful and very forgiving on the figure. No matter what body type you have, it will look great. I recommend everyone to place an order."
