Japanese Anime Speech Dataset

japanese-anime-speech is an audio-text dataset designed for the training of automatic speech recognition models. The dataset is comprised of thousands of audio clips and their corresponding transcriptions from different visual novels.

The goal of this dataset is to enhance the proficiency of automatic speech recognition systems, such as OpenAI's Whisper, in accurately transcribing dialogue from anime and other similar Japanese media. This genre is characterized by unique linguistic features and speech patterns that diverge from conventional Japanese speech.

The code used for scraping the audio will be available once I feel it is reliable enough and easy-to-use.

Changelog

V1 - This version contains 16,143 audio-text pairs from the visual novel IxSHE Tell. Some cleaning of the transcriptions has been done to get rid of unwanted characters at the start and end of lines, but I intend to do much more for the second version.
V2 - The dataset now contains 23,422 audio-text pairs from three different visual novels. Lots of cleaning has been done to remove nsfw lines, especially noises that aren't words.

Dataset information

The dataset contains 32.57 hours of labeled audio (OpenAI suggests a minimum of 5 hours for productive Whisper fine-tuning).
The average audio length is 5.0s.

The dataset is comprised of:

23,422 audio-text pairs
12,782 lines from IxSHE Tell (3,739/16,521 were filtered out)
8,102 lines from ユキイロサイン (1,842/9,944 were filtered out)
2,538 lines from 幼馴染のいる暮らし (26/2564 were filtered out)

NSFW Warning: Please be advised that the majority of the audio in this dataset is sourced from visual novels and may include content that is not suitable for all audiences, such as suggestive sounds or mature topics. Efforts have been undertaken to minimise this content.

To do

Create a dataset of over 10k items
Create a dataset of over 20k items
Compress the audio with minimal quality loss
Create a dataset of over 30k items
Create more workflows for scraping audio from visual novels that use an engine other than Artemis
Add audio from more visual novels
Convert names in transcriptions to katakana?

Use & Credit

This dataset is openly available for commercial or non-commercial use. Anyone is welcome to use this resource as they deem appropriate. However, the creator assumes no responsibility for the consequences of its use. While not mandatory, crediting this dataset with a hyperlink in any derivative work would be greatly appreciated.

I hope that by sharing this dataset, we (the open-source community) improve automatic speech recognition for anime content.
