| Here you will find details about the speech recognition metrics and datasets reported in our leaderboard. | |
| ## Metrics | |
| 🎯 Word Error Rate (WER) and Real-Time Factor (RTF) are popular metrics for evaluating the accuracy of speech recognition | |
| models by estimating how accurate the predictions from the models are and how fast they are returned. We explain them each | |
| below. | |
| ### Word Error Rate (WER) | |
| Word Error Rate is used to measure the **accuracy** of automatic speech recognition systems. It calculates the percentage | |
| of words in the system's output that differ from the reference (correct) transcript. **A lower WER value indicates higher accuracy**. | |
| ``` | |
| Example: If the reference transcript is "I really love cats," and the ASR system outputs "I don't love dogs,". | |
| The WER would be `50%` because 2 out of 4 words are incorrect. | |
| ``` | |
| For a fair comparison, we calculate **zero-shot** (i.e. pre-trained models only) *normalised WER* for all the model checkpoints. You can find the evaluation code on our [Github repository](https://github.com/huggingface/open_asr_leaderboard). To read more about how the WER is computed, refer to the [Audio Transformers Course](https://huggingface.co/learn/audio-course/chapter5/evaluation). | |
| ### Real Time Factor (RTF) | |
| Real Time Factor is a measure of the **latency** of automatic speech recognition systems, i.e. how long it takes an | |
| model to process a given amount of speech. It's usually expressed as a multiple of real time. An RTF of 1 means it processes | |
| speech as fast as it's spoken, while an RTF of 2 means it takes twice as long. Thus, **a lower RTF value indicates lower latency**. | |
| ``` | |
| Example: If it takes an ASR system 10 seconds to transcribe 10 seconds of speech, the RTF is 1. | |
| If it takes 20 seconds to transcribe the same 10 seconds of speech, the RTF is 2. | |
| ``` | |
| For the benchmark, we report RTF averaged over a 10 minute audio sample with 5 warm up batches followed 3 graded batches. | |
| ## How to reproduce our results | |
| The ASR Leaderboard will be a continued effort to benchmark open source/access speech recognition models where possible. | |
| Along with the Leaderboard we're open-sourcing the codebase used for running these evaluations. | |
| For more details head over to our repo at: https://github.com/huggingface/open_asr_leaderboard | |
| P.S. We'd love to know which other models you'd like us to benchmark next. Contributions are more than welcome! ♥️ | |
| ## Benchmark datasets | |
| Evaluating Speech Recognition systems is a hard problem. We use the multi-dataset benchmarking strategy proposed in the | |
| [ESB paper](https://arxiv.org/abs/2210.13352) to obtain robust evaluation scores for each model. | |
| ESB is a benchmark for evaluating the performance of a single automatic speech recognition (ASR) system across a broad | |
| set of speech datasets. It comprises eight English speech recognition datasets, capturing a broad range of domains, | |
| acoustic conditions, speaker styles, and transcription requirements. As such, it gives a better indication of how | |
| a model is likely to perform on downstream ASR compared to evaluating it on one dataset alone. | |
| The ESB score is calculated as a macro-average of the WER scores across the ESB datasets. The models in the leaderboard | |
| are ranked based on their average WER scores, from lowest to highest. | |
