+ # Condensed LibriSpeech ASR
66
+
67
+ This dataset is a condensed version of the [LibriSpeech ASR dataset](https://huggingface.co/datasets/openslr/librispeech_asr), created by subsampling approximately 10% of the original data from each split. It is intended for quick experimentation, prototyping, and debugging when working with Automatic Speech Recognition (ASR) tasks.
68
+
69
+ ## Dataset Details
70
+
71
+ - **Original Dataset:** [LibriSpeech ASR](https://huggingface.co/datasets/openslr/librispeech_asr)
72
+ - **Condensation Ratio:** Approximately 10% of the full dataset
73
+ - **Splits Included:**
74
+ - `train.clean.100`
75
+ - `train.clean.360`
76
+ - `train.other.500`
77
+ - `validation.clean`
78
+ - `validation.other`
79
+ - `test.clean`
80
+ - `test.other`
81
+
82
+ For each split, a default number of examples was extracted:
83
+ - **Training Splits:** 1,000 examples each
84
+ - **Validation/Test Splits:** 100 examples each
85
+
86
+ ## Data Format
87
+
88
+ Each sample in the dataset contains the following fields:
89
+
90
+ - **file:**
91
+ A path to the original audio file (FLAC format).
92
+
93
+ - **audio:**
94
+ A dictionary containing:
95
+ - `path`: Path to the audio file.
96
+ - `array`: The decoded audio waveform as a NumPy array.
97
+ - `sampling_rate`: The sampling rate (typically 16 kHz).
98
+
99
+ - **text:**
100
+ The transcription corresponding to the audio.
101
+
102
+ - **id:**
103
+ A unique identifier for the sample.
104
+
105
+ - **speaker_id:**
106
+ A unique identifier for the speaker.
107
+
108
+ - **chapter_id:**
109
+ An identifier corresponding to the audiobook chapter.
110
+
111
+ ## How Was This Dataset Created?
112
+
113
+ The condensed dataset was generated by streaming the full [LibriSpeech ASR dataset](https://huggingface.co/datasets/openslr/librispeech_asr) using the Hugging Face Datasets library and selecting approximately 10% of each split. This process preserves the original structure and fields, enabling seamless use with models and workflows designed for LibriSpeech.
114
+
115
+ ## Usage Example
116
+
117
+ Below is a Python snippet to load and inspect the dataset:
118
+
119
+ ```python
120
+ from datasets import load_dataset
121
+
122
+ # Load the condensed dataset from the Hugging Face Hub
123
+ dataset = load_dataset("nyalpatel/condensed_librispeech_asr")
124
+
125
+ # Access a specific split (e.g., test.clean)
126
+ test_dataset = dataset["test.clean"]
127
+
128
+ # Display the first example in the test set
129
+ print(test_dataset[0])
