Connecting to the Realtime API

Same over here…
WebSocket error: Error: Unexpected server response: 403

Why is your profile hidden just makes me curious as to why you would go through such extremes

@elm is a leader and well-known in the forum, I wouldn’t call it an “extreme”

Also getting a 403 error when connecting to the realtime api. If anyone figures out how to do so or finds communication from OAI on this, highly appreciated.

Has anyone gotten access yet? Keep trying every hour and is still saying access is forbidden.


:smiling_face_with_tear:

I just got access. Next challenge is to find an updated cookbook in python…

Me too just received the access . it’s amazing

I just signed in. Access from Italy, in second level developer, while first level developer (free), no access

Anyone else having trouble enabling transcription? Using NodeJS and getting

Error: {
  type: 'error',
  event_id: 'event_AEopyKok7tGfvpiXEGeYD',
  error: {
    type: 'invalid_request_error',
    code: 'unknown_parameter',
    message: "Unknown parameter: 'session.input_audio_transcription.enabled'.",
    param: 'session.input_audio_transcription.enabled',
    event_id: null
  }
}

Figured it out, if you put

"input_audio_transcription": {
     "enabled": true,
     "model": "whisper-1"
    },

it will throw that error, but if you have just

 "input_audio_transcription": {
   "model": "whisper-1"
      },

it works perfectly.

Working fine with me in python

You saved my day. Genius.

Hi, I updated the session as follows:

“input_audio_transcription”: {
“model”: “whisper-1”
},

However, I still can’t see the audio input transcription:

{“type”:“conversation.item.created”,
…,
[{“type”:“input_audio”,“transcript”:null}]}}

Has anyone successfully managed to get the audio input transcription?

Still having trouble outputting the input audio transcription as well. This is my session_update:

		session_update = {
			"type": "session.update",
			"session": {
				"modalities": ["text", "audio"],
				"instructions": "Your knowledge cutoff is 2023-10. You are a helpful assistant.",
				"voice": "alloy",
				"input_audio_format": "pcm16",
				"output_audio_format": "pcm16",
				"input_audio_transcription": {
					"model": "whisper-1"
				},
				"turn_detection": {
					"type": "server_vad",
					"threshold": 0.5,
					"prefix_padding_ms": 300,
					"silence_duration_ms": 200
				},
				"tool_choice": "auto",
				"temperature": 0.8
			}
		}

And in my console I get this:

{
  "type": "conversation.item.created",
  "event_id": "event_AFPlDoeNVja9H8l6brPsH",
  "previous_item_id": null,
  "item": {
    "id": "item_AFPlD7AJtGEl68wX3cRRV",
    "object": "realtime.item",
    "type": "message",
    "status": "completed",
    "role": "user",
    "content": [
      {
        "type": "input_audio",
        "transcript": null
      }

Can someone please help?

Having the same problem with input_audio_transcription.enabled

Ah. I see the transcription arriving in the conversation.item.input_audio_transcription.completed event

This works for connecting and getting one response, still have alot to go, but this is a functioning one off console app (P.s> this is realtime text in audio out) and the websockets have a 15 min time limit on each socket

conversation-item-input-audio-transcription-completed, it will be in this event.

i don’t have this event conversation.item.input_audio_transcription.completed

Maybe i missed something in the config ?
