I will evaluate japanese ai voice data and correct transcriptions
About this Gig
I'm Yoshiya, a native Japanese speaker with hands-on experience in Japanese speech data projects - including voice recording for AI training data, evaluating Japanese speech output, and checking AI-generated transcriptions for accuracy. If you're building Japanese TTS, ASR, or voice AI, you need a native ear. I check your audio and transcripts segment by segment and fix what machines miss: wrong kanji conversions, unnatural phrasing, misheard words, and pronunciation problems.
What I can do: - Correct Japanese speech-to-text / ASR transcripts against the audio - Evaluate recorded Japanese speech: pronunciation, naturalness, intonation, reading errors - Rate and flag segments following your guidelines or rubric - Check AI-generated Japanese voice output for unnatural or incorrect parts
Why me: - Native Japanese speaker (voice impression: male, 30s-40s) - Around 30 years of reading-aloud and speech training - a trained ear for Japanese prosody - Careful, guideline-based work: I follow your annotation rules exactly and flag unclear cases instead of guessing - Business-level Chinese as well, if your project involves Japanese-Chinese data

FAQ
What do you need from me to start?
The audio files (or links), the current transcript if you have one, and your evaluation guidelines or rubric if you use one. If you don't have guidelines, tell me your goal and I'll evaluate for accuracy and naturalness.
Which file formats can you work with?
Audio: MP3, WAV, M4A and most common formats. Transcripts/results: Excel, Google Sheets, CSV, Word, Google Docs, or your web-based annotation tool.
Can you follow our annotation guidelines exactly?
Yes. Careful, rule-based checking is my strength. Where a case is ambiguous, I'll flag it with a note rather than guessing.
Can you sign an NDA?
Yes, I'm happy to sign an NDA and keep all project data confidential.
What if some audio is unintelligible?
I'll mark those segments clearly as unintelligible with timestamps, so your team can decide whether to re-record or exclude them.
Do you also record Japanese voice data?
Yes! I also offer Japanese voice recording — please see the voice over gig on my profile, or message me about your data collection project.
