The transcribed audio data is collected from audiobooks, podcasts and YouTube, covering both read and spontaneous speaking styles, and a variety of topics, such as arts, science, sports, etc. ### Example Usage The training split has several configurations of various size: XS, S, M, L, XL. See the Section on "Data Splits" for more information. To download the XS configuration: ```python from datasets import load_dataset gs = load_dataset("speechcolab/gigaspeech", "xs", use_auth_token=True) # see structure print(gs) # load audio sample on the fly audio_input = gs["train"][0]["audio"] # first decoded audio sample transcription = gs["train"][0]["text"] # first transcription ``` It is possible to download only the development or test data: ```python gs_dev = load_dataset("speechcolab/gigaspeech", "dev", use_auth_token=True) gs_test = load_dataset("speechcolab/gigaspeech", "test", use_auth_token=True) ``` ### Supported Tasks and Leaderboards - `automatic-speech-recognition`: The dataset can be used to train a model for Automatic Speech Recognition (ASR). The model is presented with an audio file and asked to transcribe the audio file to written text. The most common evaluation metric is the word error rate (WER). The task has an active leaderboard which can be found at https://github.com/SpeechColab/GigaSpeech#leaderboard and ranks models based on their WER. ### Languages Gigaspeech contains audio and transcription data in English. ## Dataset Structure ### Data Instances ```python { 'segment_id': 'YOU0000000315_S0000660', 'speaker': 'N/A', 'text': "AS THEY'RE LEAVING CAN KASH PULL ZAHRA ASIDE REALLY QUICKLY ", 'begin_time': 2941.889892578125, 'end_time': 2945.070068359375, 'audio': { # in streaming mode 'path' will be 'xs_chunks_0000/YOU0000000315_S0000660.wav' 'path': '/home/user/.cache/huggingface/datasets/downloads/extracted/9d48cf31/xs_chunks_0000/YOU0000000315_S0000660.wav', 'array': array([0.0005188 , 0.00085449, 0.00012207, ..., 0.00125122, 0.00076294, 0.00036621], dtype=float32), 'sampling_rate': 16000 }, 'audio_id': 'YOU0000000315', 'title': 'Return to Vasselheim | Critical Role: VOX MACHINA | Episode 43', 'url': 'https://www.youtube.com/watch?v=zr2n1fLVasU', 'source': 2, 'category': 24, 'original_full_path': 'audio/youtube/P0004/YOU0000000315.opus' } ``` ### Data Fields * segment_id (string) - string id of the segment. * speaker (string) - string id of the speaker (can be "N/A"). * text (string) - transcription of the segment. * begin_time (float) - start time of the segment in an original full audio. * end_time (float32) - end time of the segment in an original full audio. * audio (Audio feature) - a dictionary containing the path to the audio, the decoded audio array, and the sampling rate. In non-streaming mode (default), the path point to the locally extracted audio. In streaming mode, the path is the relative path of an audio. segment inside its archive (as files are not downloaded and extracted locally). * audio_id (string) - string idea of the original full audio. * title (string) - title of the original full audio. * url (string) - url of the original full audio. * source (ClassLabel) - id of the audio source. Sources are audiobook (0), podcast (1), and YouYube (2). * category (ClassLabel) - id of the audio category, categories are listed below. * original_full_path (string) - the relative path to the original full audio sample in the original data directory. Categories are assigned from the following labels: "People and Blogs", "Business", "Nonprofits and Activism", "Crime", "History", "Pets and Animals", "News and Politics", "Travel and Events", "Kids and Family", "Leisure", "N/A", "Comedy", "News and Politics", "Sports", "Arts", "Science and Technology", "Autos and Vehicles", "Science and Technology", "People and Blogs", "Music", "Society and Culture", "Education", "Howto and Style", "Film and Animation", "Gaming", "Entertainment", "Travel and Events", "Health and Fitness", "audiobook". ## Data Splits The dataset has three splits: train, evaluation (dev) and test. The train split has five configurations of various sizes: XS, S, M, L, XL. Larger subsets are supersets of smaller subsets, e.g., the L subset contains all the data from the M subset. ### Transcribed Training Subsets Size | Subset | Hours | Remarks | |:---------------:|:-------------:|:-------------| | XS | 10 | System building and debugging | | S | 250 | Quick research experiments | | M | 1,000 | Large-scale research experiments | | L | 2,500 | Medium-scale industrial experiments | | XL | 10,000 | Large-scale industrial experiments | ### Transcribed Evaluation Subsets | Subset | Hours | Remarks | |:------:|:-----:|:--------| | Dev | 12 | Randomly selected from the crawled Podcast and YouTube Data | | Test | 40 | Part of the subset was randomly selected from the crawled Podcast and YouTube data; part of it was manually collected through other channels to have better coverage. | ## Dataset Creation ### Curation Rationale [More Information Needed] ### Source Data | Audio Source | Transcribed Hours | Acoustic Condition | |:-------------|:----------------------:|:-------------------| | Audiobook | 2,655 |
