Yunxi

Yunxi 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: “周日下午，我没有目的地在附近走了很久。孩子们在路面上画粉笔画，有人从阳台上传来练吉他的声音。我从市场买了一束花回家，虽然脚有些累，却觉得这个周末没有被匆忙地浪费掉。” 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 dbe6e1ce, 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.
