Job description

Japanese Audio Transcription Specialist (AI Training)

Are you a Japanese speaker based in São Paulo or elsewhere in Brazil? What if your ear for Japanese could directly shape how AI listens to and understands one of the world's most complex languages? We're looking for Japanese Audio Transcription Specialists to listen to real-world audio recordings and produce accurate, detailed transcriptions that train the next generation of AI speech systems.

About The Role

Brazil is home to the largest Japanese diaspora community in the world. Whether you're a native Japanese speaker, a Nikkei heritage speaker, or a bilingual professional with deep Japanese fluency, your listening comprehension and cultural knowledge are exactly what this role needs. This is a fully remote, flexible contract role — no AI background required.

• Organization: Alignerr
• Type: Hourly Contract
• Location: Remote
• Commitment: 10–40 hours/week

What You'll Do

• Listen to Japanese audio recordings spanning a wide range of topics, speakers, and styles — from casual conversation to formal speech
• Produce precise, verbatim transcriptions following detailed project guidelines
• Accurately capture nuances such as filler words, hesitations, speaker overlaps, and non-standard speech
• Identify and label speakers, timestamps, and audio events as required
• Apply proper Japanese orthography, punctuation, and formatting conventions consistently
• Flag unclear or inaudible segments with appropriate annotations
• Maintain high quality and consistency across large volumes of audio content
• Work independently and asynchronously — fully on your own schedule

Who You Are

• Native or near-native fluency in Japanese with excellent listening comprehension
• Strong command of Japanese writing systems — kanji, hiragana, and katakana
• Naturally detail-oriented with a patient, methodical approach to repetitive tasks
• Able to distinguish between speakers and accurately capture natural, conversational Japanese
• Comfortable working with audio playback tools and text-based interfaces
• Self-motivated and reliable when working independently without supervision
• No prior AI, transcription, or tech experience required

Nice to Have

• Experience in transcription, subtitling, captioning, or stenography
• Familiarity with Japanese dialects and regional speech patterns (Kansai, Tohoku, Kyushu, etc.)
• Background in linguistics, translation, interpretation, or Japanese language education
• Experience using transcription software or audio annotation tools
• Knowledge of specialized vocabulary in fields such as business, medicine, technology, or media
• Proficiency in English or Portuguese for communication purposes

Why Join Us

• Work on cutting-edge AI speech recognition projects alongside leading research labs
• Fully remote and flexible — work when and where it suits you
• Freelance autonomy with the structure of meaningful, task-based work
• Contribute directly to how AI understands and processes spoken Japanese worldwide
• Develop your skills in a growing field at the intersection of language and technology
• Potential for ongoing work and contract extension as new projects launch
