Parameter reference
Every voice accepts these three parameters. The ranges below apply to all of them and map straight onto the API.
| Parameter | Range | Default | What it does |
|---|---|---|---|
Raterate |
-50% ~ +100% |
+0% |
Higher is faster. +100% is nearly double speed for dense narration; -50% is a slow read. |
Pitchpitch |
-50Hz ~ +50Hz |
+0Hz |
Higher is brighter and younger; lower is deeper and more mature. Measured in hertz, not percent. |
Volumevolume |
-50% ~ +50% |
+0% |
Relative gain against the original level. Only raise it when the source itself is quiet. |

Frequently asked questions
Is this voice library free?
Yes. This site charges nothing, needs no account and does not limit how many voices you use — all 300+ are available.
How is this different from voice cloning?
These are ready-made general-purpose voices: pick one and go — fast, but not customisable. Voice cloning needs a recording of your own voice and gets closer to a specific person. Use this library for character or multilingual dubbing; use cloning to reproduce someone's timbre.
Which languages are supported?
Over 100 languages and regional accents, including Mandarin, Cantonese, English (US, UK, Australia, India, Hong Kong and more), Japanese, Korean, German, French, Spanish, Portuguese, Russian, Hindi, Vietnamese, Thai, Turkish and Arabic.
How far can rate, pitch and volume go?
Rate -50% to +100%, pitch -50Hz to +50Hz, volume -50% to +50%. Pitch is measured in hertz — it is not the same scale as rate.
Can I use the audio commercially?
The speech is generated by modern speech-synthesis models. It is fine for videos, lessons and podcasts, but follow local law and platform rules, and never use it to impersonate someone or commit fraud.
