Realtime transcription Problem - gpt-live-transcribe - no final events received

Hello Dear team

We are following the documentation here:

we tried the models:

  • gpt-live-transcribe (new one, the one we want to use)
  • gpt-realtime-whisper

In both cases we have problems.

We expect to receive both deltas and final events:

ws.on("message", (data) => {
  const event = JSON.parse(data);

  if (event.type === "conversation.item.input_audio_transcription.delta") {
    process.stdout.write(event.delta);
  }

  if (event.type === "conversation.item.input_audio_transcription.completed") {
    console.log("\nFinal transcript:", event.transcript);
  }
});

However, we are not receiving final events:

We realized that the session can be configured only with turn_detection turned off.

{
  "type": "session.update",
  "session": {
    "type": "transcription",
    "audio": {
      "input": {
        "format": {
          "type": "audio/pcm",
          "rate": 24000
        },
        "transcription": {
          "model": "gpt-live-transcribe"
        },
        "turn_detection": null
      }
    }
  }
}

If we do this, we receive only deltas but not final events

After this we follow the documentation to enable turn detection as reported here:

specifically this disclaimer

To let the server detect and commit turn boundaries, configure voice activity detection instead.

{
  "type": "session.update",
  "session": {
    "type": "transcription",
    "audio": {
      "input": {
        "format": { "type": "audio/pcm", "rate": 24000 },
        "transcription": { "model": "gpt-live-transcribe" },
        "turn_detection": {
          "type": "server_vad",
          "threshold": 0.8,
          "prefix_padding_ms": 500,
          "silence_duration_ms": 700
        }
      }
    }
  }
}

But then we get this error:

{
  "message": "Turn detection is not supported for this transcription model.",
  "type": "invalid_request_error",
  "code": "invalid_value",
  "param": "session.audio.input.turn_detection"
}

Can you please guide us and tell us what we are doing wrong?

Thanks so much guys

God bless
