I’m using the transcription endpoint at /v1/audio/transcriptions. I’ve noticed that when I use the gpt-4o-transcribe or gpt-4o-mini-transcribe models with this endpoint, the transcript that I receive back is truncated - usually sometime between 10-11 minutes into my 12-minute recording. However, whe…

Another q, have you tried .ogg in the new gpt-4o-transcribe? whisper had no problem and its how I’m gettign around the 25MB limit (by compressing the audio as much as possible) I get an error in the new model when I try upload .ogg

Same problem here. Uploading an mp3 which is well within the 25 MB limit, yet the transcription cuts off just under 10 minutes. I tried it with two audio files, one about 10m30s and the other ~12m and both cut off about the same time.

Iv had the same issue. Im using the MediaStreamTimeProcessor recorder that autoslices the audio every 45 sec. With whisper-1 it works perfectly, and I dont experience any truncated transcripts. However with the new gpt-4-transribe model, my audiochunk transcripts often lack a good part of the record…

[image] scott_no35: Trying to figure it out but cant find any solution I guess the big question here: Is this just a single AI run with one context window that can be exhausted? Or, are there internal techniques to instead split received audio and keep context down by doing similar to the 3…

I have noticed the same patterns. For example, in a 10 minute conversation (ogg format, 3.4MB file), the content from the 10th minute in the transcript is missing. I can reproduce this for gpt-4o-transcribe and gpt-4o-mini-transcribe. However, whisper-1 does produce a complete transcript.

I have same exact issue but with pyaudio recordings, split every 60 sec. It’s not the duration - it’s the context window for me. Shifting even by a couple seconds makes gtp4-transcribe understand. Otherwise, it interprets only 1 sentence. Whisper works. Temperature won’t save anyone this time. Comp…

I’m experiencing the same issue. I use the model for voice input to my computer, and after switching from Whisper to gpt-4o-transcribe, I immediately noticed this problem (with German language input). The last sentence is frequently missing from my transcriptions. Sometimes two sentences combined i…

Switched back to whisper. It leaves out whole senences all the time. Sometimes also sentences in the middle. Gpt-4o-transcribe is zero reliable and just unusable for me.

I have the same problem with all my recordings using gpt-4o-transcribe. I have chunks of 17min files of mp3 and it cuts off a bit more than 4min. I’m all the time below the 25MB limit. This is frustrating to see, especially if you have processed already a lot of files. And also if the cut is in the…

I also have the same problem. I’m sending an audio file in wav format (a call recording) that is 16MB in size and the recording is 17 minutes in length. I also have a trncated transcription, but I’m not sure where since I did it in the portal which just spits out the text. In my code (C# program) I …
