+_DESCRIPTION = """\
+Self-supervised learning (SSL) has proven vital for advancing research in
+natural language processing (NLP) and computer vision (CV). The paradigm
+pretrains a shared model on large volumes of unlabeled data and achieves
+state-of-the-art (SOTA) for various tasks with minimal adaptation. However, the
+speech processing community lacks a similar setup to systematically explore the
+paradigm. To bridge this gap, we introduce Speech processing Universal
+PERformance Benchmark (SUPERB). SUPERB is a leaderboard to benchmark the
+performance of a shared model across a wide range of speech processing tasks
+with minimal architecture changes and labeled data. Among multiple usages of the
+shared model, we especially focus on extracting the representation learned from
+SSL due to its preferable re-usability. We present a simple framework to solve
+SUPERB tasks by learning task-specialized lightweight prediction heads on top of
+the frozen shared model. Our results demonstrate that the framework is promising
+as SSL representations show competitive generalizability and accessibility
+across SUPERB tasks. We release SUPERB as a challenge with a leaderboard and a
+benchmark toolkit to fuel the research in representation learning and general
+speech processing.
+
+Note that in order to limit the required storage for preparing this dataset, the
+audio is stored in the .flac format and is not converted to a float32 array. To
+convert, the audio file to a float32 array, please make use of the `.map()`
+function as follows:
+
+
+```python
+import soundfile as sf
+
+def map_to_array(batch):
+    speech_array, _ = sf.read(batch["file"])
+    batch["speech"] = speech_array
+    return batch
+
+dataset = dataset.map(map_to_array, remove_columns=["file"])
