What Japanese dialects are included in the datasets?

Our Japanese datasets cover Standard Japanese (Hyojungo) as well as major regional dialects including Kansai-ben (Osaka/Kyoto), Tohoku-ben, and Kyushu dialects, essential for building AI that resonates with regional native speakers.

Do you provide Japanese-English parallel corpora?

Yes, we provide professional-grade Japanese-English parallel corpora, meticulously aligned by expert linguists for high-performance machine translation and cross-lingual Large Language Model (LLM) training.

How is the Keigo (honorifics) handled in the data?

Our Japanese text datasets are professionally labeled by honorific levels (Sonkeigo, Kenjougo, Teineigo), allowing for formal AI persona alignment and accurate natural language understanding in professional contexts.

Is the Japanese speech data annotated for pitch accent?

Yes, our high-fidelity Japanese speech recordings include optional metadata for pitch accent markers, which is critical for developing natural-sounding Text-to-Speech (TTS) and high-accuracy Automatic Speech Recognition (ASR) systems.
