Xiaoyi

Xiaoyi is a female 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 voice-over

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: “今天早上，我在煮咖啡前先打开了窗。街上还很安静，一辆送货的自行车慢慢经过树下。我只写下三件今天要做的小事，然后决定先好好吃早餐。原来不用急着开始，也能让平常的早晨变得轻松一些。” 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 b5235dba, 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.
