Hello! I am trying to make a script that creates a voice session for realtime inference using only Python and the OpenAI Realtime API. I do not want to pay for any SDK's such as LiveKit or Agora, I only wanna pay for the Realtime API.
#Real-time voice inference only using Python and OpenAI Realtime API

Hi @crimson anvil. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
Sure, you can use the OpenAI Realtime API to create a voice session for real-time inference. However, please note that the Realtime API is currently in beta and does not offer client-side authentication. Therefore, applications should be built to route audio from the client to an application server to the Realtime API, using the application server to securely authenticate with OpenAI.
Here is a basic example of how you can use the Realtime API with Python:
from openai import OpenAI
client = OpenAI()
response = client.audio.speech.create(
model="tts-1",
voice="alloy",
input="Hello world! This is a streaming test.",
)
response.stream_to_file("output.mp3")
This example uses the speech.create method to generate spoken audio from input text. The stream_to_file method is used to stream the audio to a file in real-time.
Please note that real-time audio is heavily affected by network conditions, and reliably delivering real-time audio to a server (e.g., from a mobile client to a backend) at scale is a challenge when network conditions are unpredictable. If you are building client-side or telephony applications where you do not have control over the reliability of the network, for production use cases OpenAI recommends that you evaluate a purpose-built third-party solution.
For more information, you can refer to the OpenAI Realtime API documentation (https://platform.openai.com/docs/guides/realtime/integration).
Please note that the OpenAI Realtime API is a paid service, and usage costs will apply according to OpenAI's pricing structure.
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

Will this have same speed results as testing the Realtime API within OpenAI's playground? I need the audio streamed like the Realtime API usually does

Let me check the knowledge base for you again. One moment! :books:
The speed of the results can depend on various factors, including the network conditions and the efficiency of your implementation. The OpenAI Realtime API is designed to support low-latency, multi-modal conversational experiences, which includes real-time audio streaming. However, achieving the same speed as testing within OpenAI's playground might require careful management of the audio data and efficient handling of the API responses.
In the Python code example provided earlier, the stream_to_file method is used to stream the audio to a file in real-time. This should provide similar performance to the OpenAI playground, but actual results can vary based on the factors mentioned above.
If you're looking to stream audio directly to a client, you might need to implement additional logic to handle the streaming. This could involve setting up a WebSocket connection or similar technology to push the audio data to the client as it's received from the API.
Please note that the OpenAI Realtime API is currently in beta, and it does not offer client-side authentication. Therefore, applications should be built to route audio from the client to an application server to the Realtime API, using the application server to securely authenticate with OpenAI.
