### Explanation |
|
|
|
|
|
We believe that rigorously measuring the quality of inference is necessary for developers and |
|
|
enterprises to make informed decisions when opting to use optimized or compressed variants of |
|
|
any machine learning model in production. To contextualize `WhisperKit`, we take the following Whisper |
|
|
implementations and benchmark them using a consistent evaluation harness: |
|
|
|
|
|
Server-side: |
|
|
- `WhisperOpenAIAPI`: [OpenAI's Whisper API](https://platform.openai.com/docs/guides/speech-to-text) |
|
|
|
|
|
($0.36 per hour of audio as of 02/29/24, 25MB file size limit per request) |
|
|
|
|
|
On-device: |
|
|
- `WhisperKit`: Argmax's implementation [[Eval Harness]](https://github.com/argmaxinc/whisperkittools/blob/main/whisperkit/pipelines.py#L100) [[Repo]](https://github.com/argmaxinc/WhisperKit) |
|
|
- `whisper.cpp`: A C++ implementation form ggerganov [[Eval Harness]](https://github.com/argmaxinc/whisperkittools/blob/main/whisperkit/pipelines.py#L212) [[Repo]](https://github.com/ggerganov/whisper.cpp) |
|
|
- `WhisperMLX`: A Python implementation from Apple MLX [[Eval Harness]](https://github.com/argmaxinc/whisperkittools/blob/main/whisperkit/pipelines.py#L338) [[Repo]](https://github.com/ml-explore/mlx-examples/blob/main/whisper/whisper/transcribe.py) |
|
|
|
|
|
(All on-device implementations are available for free under MIT license as of 03/19/2024) |
|
|
|
|
|
`WhisperOpenAIAPI` sets the reference and we assume that it is using the equivalent of [openai/whisper-large-v2](https://huggingface.co/openai/whisper-large-v2) |
|
|
in float16 precision along with additional undisclosed optimizations from OpenAI. In all measurements, we care primarily about per-example no-regressions (quantified as `qoi` below) |
|
|
which is a stricter metric compared to dataset average [Word Error RATE (WER)](https://en.wikipedia.org/wiki/Word_error_rate). A 100% `qoi` preserves perfect backwards-compatibility on the test distribution and avoids "perceived regressions", the phenomenon |
|
|
where per-example known behavior changes after a code/model update and causes divergence in downstream code or breaks the user experience itself (even if dataset averages might stay flat |
|
|
across updates). Pseudocode for `qoi`: |
|
|
|
|
|
```python |
|
|
qoi = [] |
|
|
for example in dataset: |
|
|
no_regression = wer(optimized_model(example)) <= wer(reference_model(example)) |
|
|
qoi.append(no_regression) |
|
|
qoi = (sum(qoi) / len(qoi)) * 100. |
|
|
``` |
|
|
|
|
|
Note that the ordering of models with respect to `WER` does not necessarily match the ordering with respect to `QoI`. This is because the reference model gets assigned |
|
|
a QoI of 100% by definition. Any per-example regression by other implementations get penalized while per-example improvements are not rewarded. `QoI` (higher is better) matters |
|
|
where the production behavior is established by the reference results and the goal is to not regress when switching to an optimized or compressed model. On the other hand, |
|
|
`WER` (lower is better) matters when there is no established production behavior and one is picking the best quality versus model size trade off point. |
|
|
|
|
|
We anticipate developers that use Whisper (or similar models) in production to have their own Quality Assurance test sets and [whisperkittools](https://github.com/argmaxinc/whisperkittools) offers |
|
|
the tooling necessary to run the same measurements on such custom test sets, please see the [Model Evaluation on Custom Dataset]((https://github.com/argmaxinc/whisperkittools)) for details. |
|
|
|
|
|
### Why are there so many Whisper versions? |
|
|
WhisperKit is an SDK for building speech-to-text features in apps across a wide range of Apple devices. We are working towards abstracting away the model versioning from the developer so WhisperKit |
|
|
"just works" by deploying the highest-quality model version that a particular device can execute. In the interim, we leave the choice to the developer by providing quality and size trade-offs. |
|
|
|
|
|
|
|
|
### Datasets |
|
|
- [librispeech](https://huggingface.co/datasets/argmaxinc/librispeech): ~5 hours of short English audio clips, tests short-form transcription quality |
|
|
- [earnings22](https://huggingface.co/datasets/argmaxinc/earnings22): ~120 hours of English audio clips from earnings calls with various accents, tests long-form transcription quality |
|
|
- [common_voice_17_0-argmax_subset-400](https://huggingface.co/datasets/argmaxinc/common_voice_17_0-argmax_subset-400): Up to 400 samples per language of multilingual audio clips with corresponding text, testing transcription quality across diverse languages and accents. |
|
|
|
|
|
### Reproducing Results |
|
|
Benchmark results on this page were automatically generated by [whisperkittools](https://github.com/argmaxinc/whisperkittools) using our cluster of Apple Silicon Macs as self-hosted runners on |
|
|
Github Actions. We periodically recompute these benchmarks as part of our CI pipeline. Due to [security concerns](https://docs.github.com/en/actions/security-guides/security-hardening-for-github-actions#hardening-for-self-hosted-runners), |
|
|
we are unable to open up the cluster to the public. However, any Apple Silicon Mac (even with 8GB RAM) can be used to |
|
|
run identical [evaluation jobs](#evaluation) locally. For reference, our M2 Ultra devices complete a `librispeech` + `openai/whisper-large-v3` |
|
|
evaluation in under 1 hour regardless of the Whisper implementation. Oldest Apple Silicon Macs should take less than 1 day to complete the same evaluation. |

### Glossary |
|
|
|
|
|
- `_turbo`: Indicates the presence of additional optimizations (not compression) to unlock streaming transcription |
|
|
as described in our [Blog Post](https://www.takeargmax.com/blog/whisperkit). |
|
|
|
|
|
- `_*MB`: Indicates the presence of model compression. Instead of cluttering the filename with details like |
|
|
`_AudioEncoder-5.8bits_TextDecoder-6.1bits_QLoRA-rank=16`, we choose to summarize the compression spec as the |
|
|
resulting total file size since this is what matters to developers in production. |
