About AI Training and Speech Data

AI training is the human side of building modern artificial intelligence. People transcribe, review, rate, and organize examples so that AI systems can better understand real-world language and speech.

In this project, your careful Japanese listening and writing will help prepare accurate audio data for speech-focused AI systems. The work is remote and designed for flexible part-time participation.

The Role

OpenTrain AI is seeking native Japanese speakers currently located in Japan for long-term Japanese transcription and audio review work. You will work with short Japanese audio clips and produce clean, standardized verbatim transcripts that reflect what was said.

This is not translation or creative writing. Accuracy, consistency, and careful judgment are more important than speed. The expected workload is approximately one hour per day, Monday through Friday, for 12 months or longer.

• $15 USD per hour
• Part-time contractor position
• Approximately 1 hour per day, Monday through Friday
• Flexible schedule within the required daily cadence
• Long-term, ongoing work for 12 or more months
• Japan-based applicants only

What You'll Do

You will listen closely to short recordings, follow predefined transcription rules, and make consistent decisions when audio quality is imperfect. You will also complete simple evaluation and verification steps using specified options.

• Create accurate, standardized verbatim transcripts in Japanese
• Apply Japanese writing conventions, including kanji, kana, okurigana, and punctuation
• Review audio and flag recordings that are unclear or unusable
• Mark segments that cannot be confidently understood
• Follow strict guidelines without improvising
• Prioritize consistency and accuracy throughout each task

Requirements

This role requires native-level Japanese listening and writing ability, careful attention to detail, and comfort working with detailed instructions. You must be able to handle imperfect audio and use the required conventions for unclear sections.

The stated English requirement is native or bilingual English ability. Previous transcription, captioning, subtitling, or speech data labeling and quality assurance experience is preferred but not required.

• Currently located in Japan
• Native Japanese speaker with native-level writing accuracy
• Strong command of Japanese writing conventions
• Strong listening skills and careful judgment
• Comfort following strict transcription guidelines consistently
• Reliable internet connection and a computer suitable for web-based tools
• Quality headphones and a quiet working environment
• Willingness to complete a short Japanese transcription screening sample before starting

Who Should Apply

This opportunity may suit Japanese language professionals, students, transcriptionists, captioners, subtitlers, and detail-oriented contributors who want steady part-time work in a growing AI field. It is especially relevant for applicants who enjoy listening closely, applying rules, and producing precise written language.

An intermediate experience level is indicated for this role. Experience with transcription or speech data quality work is welcome, while the core requirements are Japanese accuracy, dependable availability, and disciplined guideline use.

• Native Japanese speakers living in Japan
