似乎不支持转发 TTS api 的接口？Invalid URL (POST /audio/speech)

[Jackiexiao]

from pathlib import Path
from openai import OpenAI


# replace https://api.openai.com to access from china
base_url = "https://xxx.cc/proxy"
api_key = "sk-xxx"

client = OpenAI(
    api_key=api_key,
    base_url=base_url,
)

speech_file_path = Path(__file__).parent / "speech.mp3"
response = client.audio.speech.create(
    model="tts-1",
    voice="alloy",
    input="Today is a wonderful day to build something people love!",
)

response.stream_to_file(speech_file_path)
print(f"Done! See {speech_file_path}")

报错
