Natural, expressive voices in many languages, delivered in milliseconds from the edge. Every line is quality-checked by a speech recogniser before it ever reaches your users.
The listening room plays real phrases in every voice and language we have. Pick a sentence, compare the voices back to back, decide.
Every sentence is voiced, levelled to one consistent loudness, and transcribed back by a speech recogniser to check it says what it should.
The same text in the same voice always sounds the same: one identity, one loudness, across every app and every language.
Audio is served from a global edge network in tens of milliseconds, and phrase packs can ship inside your app for offline use.
Send a language code, or auto and we detect it. We never guess when it is ambiguous. Spanish, French, Portuguese, German, Chinese, Japanese, Korean, Hindi and Arabic are rolling out, with every language marked as pending native review until a native speaker signs it off.
