如何将Watson text to speech的输出路由/管道到本地扬声器vs终端

import requests
import os

# Step 2: 使用Watson text to speech API将文本转换为语音
text = "Hello, how are you?"
url = "https://api.example.com/text-to-speech?text=" + text

# Step 3: 获取音频文件的URL
response = requests.get(url)
audio_url = response.json()["audio_url"]

# Step 4: 下载音频文件到本地
audio_file = "output.wav"
response = requests.get(audio_url)
with open(audio_file, "wb") as file:
    file.write(response.content)

# Step 5: 使用本地音频播放器软件播放音频文件
if os.name == "nt":  # Windows系统
    os.startfile(audio_file)
else:  # 其他系统（如Linux）
    os.system("xdg-open " + audio_file)
