English-language creators, schools and companies translate their videos because four in five people on earth don't speak English, and most of them would rather watch in their own language.
Mandarin is the world's largest first language: about 988 million people grew up speaking it, and 1.18 billion speak it in all. YouTube isn't available in mainland China, but Mandarin speakers in Taiwan, Singapore, Malaysia and the worldwide diaspora are a large, high-spending audience on international platforms.
Mandarin uses four tones, plus a neutral tone, to tell words apart: mā (mother) and mǎ (horse) differ only in pitch. A natural Mandarin voice has to get the melody of every syllable right.
AutoDub's Chinese subtitles use Simplified characters, the standard in mainland China, Singapore and Malaysia. Taiwan and Hong Kong write with Traditional characters.
YouTube is blocked in mainland China, where viewers watch on Bilibili, Douyin and Youku. On YouTube, a Mandarin version reaches Taiwan, Singapore, Malaysia and Chinese speakers abroad.
English is compact: the same idea usually takes more words in Spanish, French or German, and localization teams plan for 15–35% longer text. AutoDub lets the timing stretch slightly instead of speeding the voice up, so the translated speech keeps a natural pace.
