AudioAudio Recording
I recorded high-fidelity Japanese voice samples for use in speech synthesis and ASR (Automatic Speech Recognition) AI model training. I performed detailed Japanese audio transcription and timestamp-based segmentation to create accurate datasets. I contributed to RLHF projects by evaluating and reviewing Japanese AI model outputs for linguistic quality and correctness. • Recorded Japanese voice samples and provided clear speech data for AI models. • Transcribed and segmented audio, ensuring consistency with annotation guidelines. • Evaluated Japanese language data, including formal/informal registers, honorifics, and dialectal expressions. • Promoted to Final Reviewer based on quality of submissions for RLHF projects.
