# Dataset Card for Libriheavy-HQ |
|
|
|
WIP: This dataset is still a WIP, check back later. |
|
|
|
<!-- Provide a quick summary of the dataset. --> |
|
|
|
[Libriheavy](https://huggingface.co/datasets/pkufool/libriheavy): a 50,000 hours ASR corpus with punctuation casing |
|
and context. Libriheavy is a labeled version of Libri-Light. |
|
|
|
Libriheavy-HQ replaces the default Libri-Light audio files with the highest quality available versions from librivox |
|
encoded as .wav files at a 48khz sampling rate. |
|
|
|
In most cases, this consists an upgrade of the source audio from a 64kbps .mp3 to a 128kbps .mp3. |
|
|
|
## Overview |
|
|
|
This is the Libriheavy-HQ dataset, adapted for the `datasets` library. |
|
|
|
## Usage |
|
|
|
### Subsets |
|
|
|
Currently, only the "small" subset of [Libriheavy](https://huggingface.co/datasets/pkufool/libriheavy) is available. |
|
|
|
In the future, the "medium", and "large" will be available. |
|
|
|
The default configuration is "small". |
|
|
|
- "small": 509 hours of speech. 417 speakers averaging 1.22 hours per speaker. Does not overlap with other subsets. |
|
|
|
### Example |
|
|
|
Loading the `small` config with only the `train` split. |
|
``` |
|
load_dataset("mythicinfinity/libriheavy-hq", "small", split="train") |
|
``` |
|
|
|
Streaming is also supported. |
|
``` |
|
load_dataset("mythicinfinity/libriheavy-hq", streaming=True) |
|
``` |
|
|
|
### Columns |
|
|
|
``` |

|
"id": datasets.Value("string"), |
