- ## Model details
173
-
174
- Whisper is a Transformer based encoder-decoder model, also referred to as a _sequence-to-sequence_ model.
175
- It was trained on 680k hours of labelled speech data annotated using large-scale weak supervision.
176
-
177
- The models were trained on either English-only data or multilingual data. The English-only models were trained
178
- on the task of speech recognition. The multilingual models were trained on both speech recognition and speech
179
- translation. For speech recognition, the model predicts transcriptions in the *same* language as the audio.
180
- For speech translation, the model predicts transcriptions to a *different* language to the audio.
181
-
182
- Whisper checkpoints come in five configurations of varying model sizes.
183
- The smallest four are trained on either English-only or multilingual data.
184
- The largest checkpoints are multilingual only. All ten of the pre-trained checkpoints
185
- are available on the [Hugging Face Hub](https://huggingface.co/models?search=openai/whisper). The

- ## Transcription
231
-
232
- ### English to English
233
- In this example, the context tokens are 'unforced', meaning the model automatically predicts the output language
234
- (English) and task (transcribe).
235
-
236
- ```python
237
- >>> from transformers import WhisperProcessor, WhisperForConditionalGeneration
238
- >>> from datasets import load_dataset
239
-
240
- >>> # load model and processor
241
- >>> processor = WhisperProcessor.from_pretrained("openai/whisper-small")
242
- >>> model = WhisperForConditionalGeneration.from_pretrained("openai/whisper-small")
243
- >>> model.config.forced_decoder_ids = None
244
-
245
- >>> # load dummy dataset and read audio files
246
- >>> ds = load_dataset("hf-internal-testing/librispeech_asr_dummy", "clean", split="validation")
247
- >>> sample = ds[0]["audio"]
248
- >>> input_features = processor(sample["array"], sampling_rate=sample["sampling_rate"], return_tensors="pt").input_features
249
-
250
- >>> # generate token ids
251
- >>> predicted_ids = model.generate(input_features)
252
- >>> # decode token ids to text
253
- >>> transcription = processor.batch_decode(predicted_ids, skip_special_tokens=False)
254
- ['<|startoftranscript|><|en|><|transcribe|><|notimestamps|> Mr. Quilter is the apostle of the middle classes and we are glad to welcome his gospel.<|endoftext|>']
255
-
256
- >>> transcription = processor.batch_decode(predicted_ids, skip_special_tokens=True)
257
- [' Mr. Quilter is the apostle of the middle classes and we are glad to welcome his gospel.']
258
- ```
259
- The context tokens can be removed from the start of the transcription by setting `skip_special_tokens=True`.
260
-
261
- ### French to French
262
- The following example demonstrates French to French transcription by setting the decoder ids appropriately.
263
-
264
- ```python
265
- >>> from transformers import WhisperProcessor, WhisperForConditionalGeneration
266
- >>> from datasets import Audio, load_dataset
267
-
268
- >>> # load model and processor
269
- >>> processor = WhisperProcessor.from_pretrained("openai/whisper-small")
270
- >>> model = WhisperForConditionalGeneration.from_pretrained("openai/whisper-small")
271
- >>> forced_decoder_ids = processor.get_decoder_prompt_ids(language="french", task="transcribe")
272
-
273
- >>> # load streaming dataset and read first audio sample
274
- >>> ds = load_dataset("common_voice", "fr", split="test", streaming=True)
275
- >>> ds = ds.cast_column("audio", Audio(sampling_rate=16_000))
276
- >>> input_speech = next(iter(ds))["audio"]
277
- >>> input_features = processor(input_speech["array"], sampling_rate=input_speech["sampling_rate"], return_tensors="pt").input_features
278
-
279
- >>> # generate token ids
280
- >>> predicted_ids = model.generate(input_features, forced_decoder_ids=forced_decoder_ids)
281
- >>> # decode token ids to text
282
- >>> transcription = processor.batch_decode(predicted_ids)
283
- ['<|startoftranscript|><|fr|><|transcribe|><|notimestamps|> Un vrai travail intéressant va enfin être mené sur ce sujet.<|endoftext|>']
284
-
285
- >>> transcription = processor.batch_decode(predicted_ids, skip_special_tokens=True)
286
- [' Un vrai travail intéressant va enfin être mené sur ce sujet.']
287
- ```
288
-
289
- ## Translation
290
- Setting the task to "translate" forces the Whisper model to perform speech translation.
291
-
292
- ### French to English
293
-
294
- ```python

348
-
349
- ## Long-Form Transcription
350
-
351
- The Whisper model is intrinsically designed to work on audio samples of up to 30s in duration. However, by using a chunking
352
- algorithm, it can be used to transcribe audio samples of up to arbitrary length. This is possible through Transformers
353
- [`pipeline`](https://huggingface.co/docs/transformers/main_classes/pipelines#transformers.AutomaticSpeechRecognitionPipeline)
354
- method. Chunking is enabled by setting `chunk_length_s=30` when instantiating the pipeline. It can also be extended to
355
- predict utterance level timestamps by passing `return_timestamps=True`:
356
-
357
- ```python
358
- >>> import torch
359
- >>> from transformers import pipeline
360
- >>> from datasets import load_dataset
361
-
362
- >>> device = "cuda:0" if torch.cuda.is_available() else "cpu"
363
-
364
- >>> pipe = pipeline(
365
- >>> "automatic-speech-recognition",
366
- >>> model="openai/whisper-small",
367
- >>> chunk_length_s=30,
368
- >>> device=device,
369
- >>> )
370
-
371
- >>> ds = load_dataset("hf-internal-testing/librispeech_asr_dummy", "clean", split="validation")
372
- >>> sample = ds[0]["audio"]
373
-
374
- >>> prediction = pipe(sample.copy())["text"]
375
- " Mr. Quilter is the apostle of the middle classes, and we are glad to welcome his gospel."
376
-
377
- >>> # we can also return timestamps for the predictions
378
- >>> prediction = pipe(sample, return_timestamps=True)["chunks"]
379
- [{'text': ' Mr. Quilter is the apostle of the middle classes and we are glad to welcome his gospel.',
380
- 'timestamp': (0.0, 5.44)}]
381
- ```
382
-
383
- ## Fine-Tuning
384
-
385
- The pre-trained Whisper model demonstrates a strong ability to generalise to different datasets and domains. However,
386
- its predictive capabilities can be improved further for certain languages and tasks through *fine-tuning*. The blog
387
- post [Fine-Tune Whisper with 🤗 Transformers](https://huggingface.co/blog/fine-tune-whisper) provides a step-by-step
388
- guide to fine-tuning the Whisper model with as little as 5 hours of labelled data.
389
-
390
- ### Evaluated Use
391
-
392
- The primary intended users of these models are AI researchers studying robustness, generalization, capabilities, biases, and constraints of the current model. However, Whisper is also potentially quite useful as an ASR solution for developers, especially for English speech recognition. We recognize that once models are released, it is impossible to restrict access to only “intended” uses or to draw reasonable guidelines around what is or is not research.
393
-
394
- The models are primarily trained and evaluated on ASR and speech translation to English tasks. They show strong ASR results in ~10 languages. They may exhibit additional capabilities, particularly if fine-tuned on certain tasks like voice activity detection, speaker classification, or speaker diarization but have not been robustly evaluated in these areas. We strongly recommend that users perform robust evaluations of the models in a particular context and domain before deploying them.
395
-
396
- In particular, we caution against using Whisper models to transcribe recordings of individuals taken without their consent or purporting to use these models for any kind of subjective classification. We recommend against use in high-risk domains like decision-making contexts, where flaws in accuracy can lead to pronounced flaws in outcomes. The models are intended to transcribe and translate speech, use of the model for classification is not only not evaluated but also not appropriate, particularly to infer human attributes.
397
 
398
 
399
  ## Training Data
400
 
401
- The models are trained on 680,000 hours of audio and the corresponding transcripts collected from the internet. 65% of this data (or 438,000 hours) represents English-language audio and matched English transcripts, roughly 18% (or 126,000 hours) represents non-English audio and English transcripts, while the final 17% (or 117,000 hours) represents non-English audio and the corresponding transcript. This non-English data represents 98 different languages.
402
-
403
- As discussed in [the accompanying paper](https://cdn.openai.com/papers/whisper.pdf), we see that performance on transcription in a given language is directly correlated with the amount of training data we employ in that language.
404
-
405
-
406
- ## Performance and Limitations
407
-
408
- Our studies show that, over many existing ASR systems, the models exhibit improved robustness to accents, background noise, technical language, as well as zero shot translation from multiple languages into English; and that accuracy on speech recognition and translation is near the state-of-the-art level.
409
-
410
- However, because the models are trained in a weakly supervised manner using large-scale noisy data, the predictions may include texts that are not actually spoken in the audio input (i.e. hallucination). We hypothesize that this happens because, given their general knowledge of language, the models combine trying to predict the next word in audio with trying to transcribe the audio itself.
411
-
412
- Our models perform unevenly across languages, and we observe lower accuracy on low-resource and/or low-discoverability languages or languages where we have less training data. The models also exhibit disparate performance on different accents and dialects of particular languages, which may include higher word error rate across speakers of different genders, races, ages, or other demographic criteria. Our full evaluation results are presented in [the paper accompanying this release](https://cdn.openai.com/papers/whisper.pdf).
413
-
414
- In addition, the sequence-to-sequence architecture of the model makes it prone to generating repetitive texts, which can be mitigated to some degree by beam search and temperature scheduling but not perfectly. Further analysis on these limitations are provided in [the paper](https://cdn.openai.com/papers/whisper.pdf). It is likely that this behavior and hallucinations may be worse on lower-resource and/or lower-discoverability languages.
415
-
416
-
417
- ## Broader Implications
418
-
419
- We anticipate that Whisper models’ transcription capabilities may be used for improving accessibility tools. While Whisper models cannot be used for real-time transcription out of the box – their speed and size suggest that others may be able to build applications on top of them that allow for near-real-time speech recognition and translation. The real value of beneficial applications built on top of Whisper models suggests that the disparate performance of these models may have real economic implications.
420
-
421
- There are also potential dual use concerns that come with releasing Whisper. While we hope the technology will be used primarily for beneficial purposes, making ASR technology more accessible could enable more actors to build capable surveillance technologies or scale up existing surveillance efforts, as the speed and accuracy allow for affordable automatic transcription and translation of large volumes of audio communication. Moreover, these models may have some capabilities to recognize specific individuals out of the box, which in turn presents safety concerns related both to dual use and disparate performance. In practice, we expect that the cost of transcription is not the limiting factor of scaling up surveillance projects.
