Yunjian

Yunjian is a male Mandarin Chinese AI voice rated D on the OfflineTTS quality scale. Speech synthesis runs in your browser with no signup or per-character fees.

Best for: General purpose

Quality rating explained: D is a catalog discovery label, not a measured MOS score, a public leaderboard position, or a guarantee for your script. Audition names, numbers, pacing, and chunk joins before publishing.

Non-English Kokoro voices use the lightweight OfflineTTS phonemization service for pronunciation tokens, followed by local WebGPU/WASM waveform generation on your device.

Preview transcript: the sample player above reads: “朋友发消息问我，下班后要不要沿着河边走一走。我们没有特别的安排，只是穿上舒服的鞋，慢慢看天色落下来。有时候，一天真正需要的并不是热闹的计划，而是一段不必赶路的散步和轻松的聊天。” Listen to that clip before generating your own text; it is the shortest way to judge pronunciation, pace, and whether the Mandarin Chinese phonemization path fits your script.

Reviewing Mandarin Chinese text with this preset: Mandarin carries tone, and many characters have more than one reading depending on context. Polyphones, erhua, and numbers read as digits (phone numbers) versus quantities are the common failure points, so listen to names and figures before publishing.

Grade context: A D grade marks a visibly weaker asset. Use it knowingly, in short takes, and only when its specific texture is the point.

What the browser downloads: For this Mandarin Chinese preset, Kokoro needs phoneme tokens that the browser phonemizer does not produce, so the text is sent to the OfflineTTS phonemization endpoint before the local model synthesizes audio. The audio itself is still generated on your device.

Asset identity: this preset maps to the cached asset fingerprint 76cbf8ba, so it can be told apart from a same-named voice on another engine even when the label in the picker looks identical.

Other Mandarin Chinese voices: Xiaobei (female, grade D), Xiaoni (female, grade D), Xiaoxiao (female, grade D). Switching between them on the same sentence is the fastest way to hear whether one suits the script better.
