# 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](https://huggingface.co/openai/whisper-large-v2), 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](https://huggingface.co/openai/whisper-large-v2) 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)

# To do

* [X] Create a dataset of over 10k items
* [X] Create a dataset of over 20k items
* [X] 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.
