+ # English Audio Dataset from YouTube
46
+
47
+ This dataset contains English audio segments extracted from various YouTube channels, along with corresponding transcription metadata. The data is intended for training automatic speech recognition (ASR) models.
48
+
49
+ ## Data Source and Processing
50
+
51
+ The data was obtained through the following process:
52
+
53
+ 1. **Download:** Audio (`.m4a`) and available English subtitles (`.srt` for `en`, `en.j3PyPqV-e1s`) were downloaded from selected YouTube channels. This raw data, along with video metadata (`metadata.csv`), is stored initially in a `data/{channel_id}/` directory structure.
54
+ 2. **Segmentation:** The raw audio files were segmented based on the timing information in the `.srt` files.
55
+ - Audio files are splitted by SRT segments and then combined to a maximum duration less than but close to 30 seconds per group for Whisper.
56
+ - The corresponding audio portions for each group are extracted using `ffmpeg` and saved as `.mp3` files at a 16000 Hz sample rate.
57
+ - Metadata for each segment, including channel/video info and the text/timing of subtitles within the segment, is saved in a corresponding `.json` file.
58
+
59
+ ## Intermediate Dataset Structure (`dataset` directory)
60
+
61
+ Before being packaged into TAR archives for Hugging Face, the segmented data resides in the `dataset` directory with the following structure:
62
+
63
+ ```
64
+ dataset/
65
+ └── {channel_id}/ # Directory named after the YouTube channel ID
66
+ └── {video_id}/ # Directory named after the YouTube video ID
67
+ ├── {video_id}_{group_name}.mp3 # Segmented audio file
68
+ ├── {video_id}_{group_name}.json # Corresponding metadata file
69
+ └── ...
70
+ ```
71
+
72
+ - **`{channel_id}`:** The ID of the YouTube channel (e.g., `greenbeanmediaofficial`).
73
+ - **`{video_id}`:** The unique identifier for the YouTube video.
74
+ - **`{group_name}`:** Represents the subtitles included in the segment. It's either the index of the first subtitle (e.g., `1`) if the group contains only one, or a range indicating the first and last subtitle indices (e.g., `1-5`) if the group contains multiple subtitles.
75
+
76
+ ## Dataset Summary
77
+
78
+ The dataset comprises audio from the following channels:
79
+

102
+ ## Loading the Data
103
+
104
+ You can load the data using the Hugging Face `datasets` library:
105
+
106
+ ```python
107
+ import os
108
+
109
+ from datasets import load_dataset
110
+
111
+ ds = load_dataset(
112
+ "OrcinusOrca/YouTube-English",
113
+ "all", # or channel_id as config
114
+ split="train",
115
+ streaming=False, # or True
116
+ num_proc=os.cpu_count(),
117
+ )
118
+ ```
