- # Whisper
116
-
117
- Whisper is a pre-trained model for automatic speech recognition (ASR) and speech translation. Trained on 680k hours
118
- of labelled data, Whisper models demonstrate a strong ability to generalise to many datasets and domains **without** the need
119
- for fine-tuning.
120
-
121
- Whisper was proposed in the paper [Robust Speech Recognition via Large-Scale Weak Supervision](https://arxiv.org/abs/2212.04356)
122
- by Alec Radford et al. from OpenAI. The original code repository can be found [here](https://github.com/openai/whisper).
123
-
124
- Whisper `large-v3` has the same architecture as the previous large models except the following minor differences:
125
-
126
- 1. The input uses 128 Mel frequency bins instead of 80
127
- 2. A new language token for Cantonese
128
-
129
- The Whisper `large-v3` model is trained on 1 million hours of weakly labeled audio and 4 million hours of pseudolabeled audio collected using Whisper `large-v2`.
130
- The model was trained for 2.0 epochs over this mixture dataset.
131
 
132
- The `large-v3` model shows improved performance over a wide variety of languages, showing 10% to 20% reduction of errors compared to Whisper `large-v2`.
133
 
 
 
 
134
 
135
- **Disclaimer**: Content for this model card has partly been written by the Hugging Face team, and parts of it were
136
- copied and pasted from the original model card.
137
-
138
- ## Model details
139
-
140
- Whisper is a Transformer based encoder-decoder model, also referred to as a _sequence-to-sequence_ model.
141
- It was trained on 1 million hours of weakly labeled audio and 4 million hours of pseudolabeled audio collected using Whisper `large-v2`.
142
 
143
- The models were trained on either English-only data or multilingual data. The English-only models were trained
144
- on the task of speech recognition. The multilingual models were trained on both speech recognition and speech
145
- translation. For speech recognition, the model predicts transcriptions in the *same* language as the audio.
146
- For speech translation, the model predicts transcriptions to a *different* language to the audio.
147
 
148
- Whisper checkpoints come in five configurations of varying model sizes.
149
- The smallest four are trained on either English-only or multilingual data.
150
- The largest checkpoints are multilingual only. All ten of the pre-trained checkpoints
151
- are available on the [Hugging Face Hub](https://huggingface.co/models?search=openai/whisper). The
152
- checkpoints are summarised in the following table with links to the models on the Hub:

164
- ## Usage
165
 
166
- Whisper `large-v3` is supported in Hugging Face πŸ€— Transformers. To run the model, first
167
- install the Transformers library through the GitHub repo. For this example, we'll also install πŸ€— Datasets to load toy
168
- audio dataset from the Hugging Face Hub:
169
 
170
  ```bash
171
- pip install --upgrade pip
172
- pip install --upgrade git+https://github.com/huggingface/transformers.git accelerate datasets[audio]
173
- ```
174
-
175
- ### Short-Form Transcription
176
-
177
- The model can be used with the [`pipeline`](https://huggingface.co/docs/transformers/main_classes/pipelines#transformers.AutomaticSpeechRecognitionPipeline)
178
- class to transcribe short-form audio files (< 30-seconds) as follows:
179
-
180
- ```python
181
- import torch
182
- from transformers import AutoModelForSpeechSeq2Seq, AutoProcessor, pipeline
183
- from datasets import load_dataset
184
-
185
-
186
- device = "cuda:0" if torch.cuda.is_available() else "cpu"
187
- torch_dtype = torch.float16 if torch.cuda.is_available() else torch.float32
188
-
189
- model_id = "openai/whisper-large-v3"
190
-
191
- model = AutoModelForSpeechSeq2Seq.from_pretrained(
192
- model_id, torch_dtype=torch_dtype, low_cpu_mem_usage=True, use_safetensors=True
193
- )
194
- model.to(device)
195
-
196
- processor = AutoProcessor.from_pretrained(model_id)
197
-
198
- pipe = pipeline(
199
- "automatic-speech-recognition",
200
- model=model,
201
- tokenizer=processor.tokenizer,
202
- feature_extractor=processor.feature_extractor,
203
- max_new_tokens=128,
204
- chunk_length_s=30,
205
- batch_size=16,
206
- return_timestamps=True,
207
- torch_dtype=torch_dtype,
208
- device=device,
209
- )
210
-
211
- dataset = load_dataset("distil-whisper/librispeech_long", "clean", split="validation")
212
- sample = dataset[0]["audio"]
213
-
214
- result = pipe(sample)
215
- print(result["text"])
216
- ```
217
-
218
- To transcribe a local audio file, simply pass the path to your audio file when you call the pipeline:
219
- ```diff
220
- - result = pipe(sample)
221
- + result = pipe("audio.mp3")
222
- ```
223
-
224
- Whisper predicts the language of the source audio automatically. If the source audio language is known *a-priori*, it
225
- can be passed as an argument to the pipeline:
226
-
227
- ```python
228
- result = pipe(sample, generate_kwargs={"language": "english"})
229
- ```
230
-
231
- By default, Whisper performs the task of *speech transcription*, where the source audio language is the same as the target
232
- text language. To perform *speech translation*, where the target text is in English, set the task to `"translate"`:
233
-
234
- ```python
235
- result = pipe(sample, generate_kwargs={"task": "translate"})
236
- ```
237
-
238
- Finally, the model can be made to predict timestamps. For sentence-level timestamps, pass the `return_timestamps` argument:
239
-
240
- ```python
241
- result = pipe(sample, return_timestamps=True)
242
- print(result["chunks"])
243
- ```
244
-
245
- And for word-level timestamps:
246
-
247
- ```python
248
- result = pipe(sample, return_timestamps="word")
249
- print(result["chunks"])
250
- ```
251
-
252
- The above arguments can be used in isolation or in combination. For example, to perform the task of speech transcription
253
- where the source audio is in French, and we want to return sentence-level timestamps, the following can be used:
254
-
255
- ```python
256
- result = pipe(sample, return_timestamps=True, generate_kwargs={"language": "french", "task": "translate"})
257
- print(result["chunks"])
258
- ```

-
260
- <details>
261
-
262
- <summary> For more control over the generation parameters, use the model + processor API directly: </summary>
263
-
264
- Ad-hoc generation arguments can be passed to `model.generate`, including `num_beams` for beam-search, `return_timestamps`
265
- for segment-level timestamps, and `prompt_ids` for prompting. See the [docstrings](https://huggingface.co/docs/transformers/en/model_doc/whisper#transformers.WhisperForConditionalGeneration.generate)
266
- for more details.

- ### Sequential Long-Form
311
-
312
- This algorithm uses a sliding window for buffered inference of long audio files (> 30-seconds),
313
- and returns more accurate transcriptions compared to the [chunked long-form algorithm](#chunked-long-form).
314
-
315
- The sequential long-form algorithm should be used in either of the following scenarios:
316
- 1. Transcription accuracy is the most important factor, and latency is less of a consideration
317
- 2. You are transcribing **batches** of long audio files, in which case the latency of sequential is comparable to chunked, while being up to 0.5% WER more accurate
318
-
319
- The [`pipeline`](https://huggingface.co/docs/transformers/main_classes/pipelines#transformers.AutomaticSpeechRecognitionPipeline)
320
- class can be used to transcribe long audio files with the sequential algorithm as follows:
321
-

411

412
- ### Chunked Long-Form
413
-
414
- large-v3 remains compatible with the Transformers chunked long-form algorithm. This algorithm should be used when
415
- a single large audio file is being transcribed and the fastest possible inference is required. In such circumstances,
416
- the chunked algorithm is up to 9x faster than OpenAI's sequential long-form implementation (see Table 7 of the
417
- [Distil-Whisper paper](https://arxiv.org/pdf/2311.00430.pdf)).
418
-
419
- To enable chunking, pass the `chunk_length_s` parameter to the `pipeline`. For distil-large-v3, a chunk length of 25-seconds
420
- is optimal. To activate batching over long audio files, pass the argument `batch_size`:
421
 
422
  ```python
423
- import torch
424
- from transformers import AutoModelForSpeechSeq2Seq, AutoProcessor, pipeline
425
- from datasets import load_dataset
426
-
427
-
428
- device = "cuda:0" if torch.cuda.is_available() else "cpu"
429
- torch_dtype = torch.float16 if torch.cuda.is_available() else torch.float32
430
 
431
- model_id = "openai/whisper-large-v3"
432
-
433
- model = AutoModelForSpeechSeq2Seq.from_pretrained(
434
- model_id, torch_dtype=torch_dtype, low_cpu_mem_usage=True, use_safetensors=True
435
  )
436
- model.to(device)
437
-
438
- processor = AutoProcessor.from_pretrained(model_id)
439
 
440
- pipe = pipeline(
441
- "automatic-speech-recognition",
442
- model=model,
443
- tokenizer=processor.tokenizer,
444
- feature_extractor=processor.feature_extractor,
445
- max_new_tokens=128,
446
- chunk_length_s=25,
447
- batch_size=16,
448
- torch_dtype=torch_dtype,
449
- device=device,
450
  )
451
 
452
- dataset = load_dataset("distil-whisper/librispeech_long", "clean", split="validation")
453
- sample = dataset[0]["audio"]
454
-
455
- result = pipe(sample)
456
- print(result["text"])
457
- ```
458
-
459
- ### Additional Speed & Memory Improvements
460
-
461
- You can apply additional speed and memory improvements to Distil-Whisper to further reduce the inference speed and VRAM
462
- requirements. These optimisations primarily target the attention kernel, swapping it from an eager implementation to a
463
- more efficient flash attention version.
464
-
465
- #### Flash Attention 2
466
-
467
- We recommend using [Flash-Attention 2](https://huggingface.co/docs/transformers/main/en/perf_infer_gpu_one#flashattention-2)
468
- if your GPU allows for it. To do so, you first need to install [Flash Attention](https://github.com/Dao-AILab/flash-attention):
469
-
470
- ```
471
- pip install flash-attn --no-build-isolation
472
- ```
473
-
474
- Then pass `attn_implementation="flash_attention_2"` to `from_pretrained`:
475
-
476

- #### Torch Scale-Product-Attention (SDPA)
482
-
483
- If your GPU does not support Flash Attention, we recommend making use of PyTorch [scaled dot-product attention (SDPA)](https://pytorch.org/docs/stable/generated/torch.nn.functional.scaled_dot_product_attention.html).
484
- This attention implementation is activated **by default** for PyTorch versions 2.1.1 or greater. To check
485
- whether you have a compatible PyTorch version, run the following Python code snippet:
486
-
487
- ```python
488
- from transformers.utils import is_torch_sdpa_available
489
-
490
- print(is_torch_sdpa_available())
491
- ```
492
-
493
- If the above returns `True`, you have a valid version of PyTorch installed and SDPA is activated by default. If it
494
- returns `False`, you need to upgrade your PyTorch version according to the [official instructions](https://pytorch.org/get-started/locally/)
495
-
496
- Once a valid PyTorch version is installed, SDPA is activated by default. It can also be set explicitly by specifying
497
- `attn_implementation="sdpa"` as follows:
498
-
499
- ```diff
500
- - model = AutoModelForSpeechSeq2Seq.from_pretrained(model_id, torch_dtype=torch_dtype, low_cpu_mem_usage=True, use_safetensors=True)
501
- + model = AutoModelForSpeechSeq2Seq.from_pretrained(model_id, torch_dtype=torch_dtype, low_cpu_mem_usage=True, use_safetensors=True, attn_implementation="sdpa")
502
  ```
503
 
504
- For more information about how to use the SDPA refer to the [Transformers SDPA documentation](https://huggingface.co/docs/transformers/en/perf_infer_gpu_one#pytorch-scaled-dot-product-attention).

- ## Fine-Tuning
515
 
516
- The pre-trained Whisper model demonstrates a strong ability to generalise to different datasets and domains. However,
517
- its predictive capabilities can be improved further for certain languages and tasks through *fine-tuning*. The blog
518
- post [Fine-Tune Whisper with πŸ€— Transformers](https://huggingface.co/blog/fine-tune-whisper) provides a step-by-step
519
- guide to fine-tuning the Whisper model with as little as 5 hours of labelled data.
520
-
521
- ### Evaluated Use
522
-
523
- 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 β€œintended” uses or to draw reasonable guidelines around what is or is not research.
524
-
525
- 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.
526
-
527
- 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.
528
-
529
-
530
- ## Training Data
531
-
532
- The models are trained on 1 million hours of weakly labeled audio and 4 million hours of pseudolabeled audio collected using Whisper `large-v2`.
533
 
534
- 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.
535
 
 
536
 
537
- ## Performance and Limitations
538
 
539
- 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.
 
 
 
 
 
 
540
 
541
- 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.
542
 
543
- 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).
 
 
 
 
 
544
 
545
- 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.
546
 
 
 
 
 
 
547
 
548
- ## Broader Implications
549
 
550
- 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.
 
 
551
 
552
- 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.
