Chinese to English Live Captions — Mandarin & Cantonese AI Translation
Translate Chinese to English on screen as it's spoken. Live Subtitles is an AI captioning app for Windows and macOS that handles Mandarin and Cantonese, simplified and traditional characters, with real-time English translation. Works on iQiyi, Viki, Bilibili, YouTube, business Zoom calls, and any other audio source — including C-drama episodes without official English subtitles.
Why Chinese-to-English needs more than one tool
"Chinese" isn't a single language and the writing system is one of the world's most complex. Three structural facts shape what good captioning needs to handle:
- Mandarin and Cantonese are different languages. They share most written Chinese but pronunciation, vocabulary, and grammar diverge. A Cantonese speaker and a Mandarin speaker often can't understand each other in conversation. Captioning needs to know which one is being spoken.
- Simplified vs traditional characters depend on region. Mainland China and Singapore use simplified; Taiwan and Hong Kong use traditional. Most learners pick one to focus on — captions need to render in the chosen script, not auto-convert.
- Tones change meaning. Mandarin has four lexical tones plus a neutral tone; same syllable, different tone, different word entirely. Recognition has to handle tones correctly to produce the right characters.
Live Subtitles handles all three: Mandarin and Cantonese as separate models, simplified and traditional script options, and tone-aware character output.
Setup: 4 steps, ~2 minutes
- Install Live Subtitles. Microsoft Store or Mac App Store. Free trial.
- Pick your Chinese variant. Mandarin (simplified) for mainland content, Mandarin (traditional) for Taiwanese content, or Cantonese (traditional) for Hong Kong content.
- Enable dual subtitles. Chinese on top, English underneath, on the same overlay.
- Open any Chinese audio. iQiyi, Viki, Bilibili, YouTube, Zoom — captions appear above the active window.
Watch and listen to Chinese content with English subtitles
C-drama on Viki, iQiyi, YouKu
Chinese drama (xianxia, costume drama, modern romance, suspense) has a global audience. Viki has the largest English-subtitled C-drama catalog, but only a fraction of new releases get fan-subbed quickly. iQiyi and YouKu host the original Chinese content first, often without English subs. Live Subtitles provides immediate captions for any new release.
Bilibili — Chinese YouTube alternative
Bilibili is the dominant video platform for Chinese-language vlogs, gaming streams, anime communities, educational content, and creator videos. Almost none of it has English subtitles. Live Subtitles makes Bilibili accessible the same way it makes YouTube accessible — system-level audio capture, no extension required.
YouTube — Chinese creators, news, gaming
Mainland-blocked but widely consumed by overseas Chinese, YouTube hosts NTDTV, BBC Chinese, RFA, and a long tail of Mandarin and Cantonese creators. Auto-CC accuracy on Chinese is unreliable; Live Subtitles produces consistently readable captions in your chosen script.
Business Zoom, Teams, Webex calls with Chinese partners
Tech, manufacturing, e-commerce, and finance industries do extensive business with China. Live Subtitles delivers real-time English captioning of incoming Mandarin or Cantonese during calls — without requiring the Chinese side to install anything or change their conferencing setup.
Chinese podcasts and radio
Mandarin podcasts (故事FM, 声东击西) and Cantonese podcasts (香港00s) are growing on Spotify and Apple Podcasts. Audio-only content is the hardest material for second-language listeners. Live Subtitles works identically on audio sources, generating both Chinese transcript and English translation.

Use cases by audience
C-drama and Chinese variety show fans
Fans of The Untamed, Story of Yanxi Palace, Nirvana in Fire, and Chinese variety shows (Sisters Who Make Waves, Street Dance of China) face long fan-sub waits for new episodes. Live Subtitles eliminates the wait — watch as it airs.
Chinese learners (HSK 3–6)
HSK listening sections at level 4 and above test natural-speed Mandarin. Textbook drills don't transfer; only authentic content does. Live Subtitles turns C-drama, vlogs, and Bilibili content into HSK prep — hear native speech, read characters, fall back on English when needed.
US/EU professionals working with China
Manufacturing, supply chain, and tech industries do extensive business with mainland China. Real-time English captioning of incoming Mandarin during calls helps non-Chinese-speaking staff parse meeting dynamics, including business-formality cues that signal authority and consensus.
Heritage speakers and overseas Chinese communities
Second-generation overseas Chinese who grew up bilingual but lost reading proficiency use Live Subtitles to reconnect with Chinese-language news, drama, and family-region content while keeping English as a comprehension safety net.
Tips for the best Chinese-to-English quality
- Pick the right Chinese variant for the content. Mainland TV / mainland YouTube creators → Mandarin (simplified). Taiwanese drama → Mandarin (traditional). Hong Kong TVB content → Cantonese (traditional). The wrong variant produces garbled output.
- Wired headphones over Bluetooth for cleaner caption quality on tonal Mandarin — Bluetooth audio compression can blur tone distinctions.
- Position the overlay below the video frame. Chinese characters take up vertical space; both lines fit comfortably below 16:9 video.
- Disable streaming-platform subtitles when using Live Subtitles dual mode — two subtitle systems creates visual noise.
- For Cantonese-Mandarin code-switching content (HK news interviewing mainland guests), pick the dominant language; the model handles the secondary language passably and the dual-subtitle view fills the gap.
- Export transcripts for HSK study. Watch first, then re-read the Chinese transcript looking up unfamiliar characters. Faster vocabulary growth than from textbook lists.
