The REST endpoint is a drop-in replacement for the OpenAI Audio API: 
from openai import OpenAI

client = OpenAI(
    api_key="YOUR_TELNYX_API_KEY",
    base_url="https://api.telnyx.com/v2"
)

response = client.audio.speech.create(
    model="tts-1-hd",
    voice="astra",
    input="Hello from Telnyx."
)

response.stream_to_file("output.mp3")
