As a native Chinese speaker, I have labeled various data types, including images and text, which has significantly improved AI model performance in natural language processing.

It's a project on Alignerr, including over 4000 audio data clips in Chinese, including Mandarin and Cantonese. What was required to do is listening to the audio and write down its transcription. The duration of the clips varied from 10 sec to less than one minute. I worked 10+ hours through one week on it.
