Yunyang

Yunyang 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: “地铁晚了几分钟，我便有时间认真看看站台对面的那家小书店。橱窗里摆着平装书和手写的推荐卡。我想周六再来一次，挑一本平时不会主动选择的书。原来等待的时候，也可以给自己找到一个小小的期待。” 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 5238ac22, 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.
