Japanese Language Data

Japanese is spoken by over 125 million people, primarily in Japan, and is characterized by a complex writing system (kanji, hiragana, katakana), politeness levels, and notable dialectal variation (Tokyo, Kansai, Tohoku, Kyushu, etc.). These linguistic features—honorifics, morphological agglutination, and script mixing—make region- and register-aware datasets essential for accurate NLP, ASR, translation, and conversational AI. High-quality Japanese datasets improve performance in tasks such as intent detection, sentiment analysis, machine translation, search relevance, and dialog systems.

Japanese Voice Data

Harness the power of Japanese voice data to enhance your AI systems 

Japanese voice data is foundational for ASR, TTS, voice assistants, and conversational agents that must respect register, dialect, and prosody. Our Japanese speech collections include read speech, conversational speech, scripted recordings, spontaneous dialogue, and bilingual (Japanese–English) interactions where needed. We record across acoustic environments to ensure robust model behavior in real-world conditions.
