Hi everyone.  
I want to use whisper to do speech recognition on one minutes voices. every thing is fine, but I get this warning:

```auto
Whisper did not predict an ending timestamp which can happen if audio is cut off in the middle of a word. Also make sure WhisperTimeStampLogitsProcessor was used during generation.

```

Firs of all: what is `WhisperTimeStampLogitsProcessor`? I couldn’t find it in any documentation.  
Secondly, Can this affect the performance of speech recognition? How do I fix it? What things I can try?  
From the voices, the end of speech is very clear.

Here are the codes that led to this warning message?

```auto
def load_model(model_id: str) -> None:
    device = "cuda:0" if torch.cuda.is_available() else "cpu"
    torch_dtype = torch.float16 if torch.cuda.is_available() else torch.float32
    model = AutoModelForSpeechSeq2Seq.from_pretrained(
        model_id, torch_dtype=torch_dtype, low_cpu_mem_usage=True, use_safetensors=True
    )
    model.to(device)

    processor = AutoProcessor.from_pretrained(model_id)

    pipe = pipeline(
        "automatic-speech-recognition",
        model=model,
        tokenizer=processor.tokenizer,
        feature_extractor=processor.feature_extractor,
        max_new_tokens=128,
        chunk_length_s=30,
        batch_size=16,
        return_timestamps=True,
        torch_dtype=torch_dtype,
        device=device,
    )
    return pipe
def batch_transcribe(file_addresses: list[str], pipe: pipeline, language: str) -> tuple:
    dataset = AudioDataset(file_addresses, language)
    dataloader = DataLoader(dataset, batch_size=16, shuffle=False)

    text_results = []
    raw_results = []

    for batch_file_addresses in tqdm.tqdm(dataloader):
        batch_res = pipe(batch_file_addresses,return_timestamps="word", generate_kwargs={"language": language})
        for res, file_address in zip(batch_res, batch_file_addresses):
            res['file_address'] = file_address
            res['language'] = language
            raw_results.append(res)
            text_results.append(res['text'])
    return (raw_results, text_results)

def transcribe_audio(audio_file: str, pipe: pipeline, language: str) -> dict:
    result = pipe(audio_file, return_timestamps=True, generate_kwargs={"language": language}) 
    return result

model = "openai/whisper-large"
pipe = load_model(model)
tmp_detail = metadata.loc[metadata['language'] == language].copy()
(raw_results , text_results) = batch_transcribe(dataset[language], pipe, language=language_map[language])

```

Any discussion or suggestion is welcome about this topic. I’d like to know why might this happen and what effects can it have.

I’m having the same problem. Have you found a resolution?

Any luck? Were you able to solve this? @flabbaf97

It [seems to be a class specific to Hugging Face Transformers](https://huggingface.co/datasets/John6666/forum1/blob/main/whisper_timestamp_warning.md).
