Portuguese TTS questions

Is Audexum's Portuguese European or Brazilian?

The Portuguese voice model is trained on a neutral Portuguese that is intelligible in both European and Brazilian contexts. Brazilian Portuguese has distinct vowel quality and prosody. For content specifically targeting Brazil, the accent will be perceived as slightly European.

Does Audexum correctly render Portuguese nasal diphthongs?

Yes. Portuguese nasal diphthongs (ão, ãe, õe, em/ém, im/ím) are phonetically complex. Audexum renders them with the correct nasalization, not as plain oral vowels.

Is Portuguese on the free tier?

Yes. Portuguese is available on the free plan (2,000 credits + 250 a day), no credit card.

What's the API call for Portuguese TTS?

POST to https://audexum.com/api/synthesize with body: { "text": "Bem-vindo ao Audexum.", "voice": "F1", "lang": "pt" }. Authorization: Bearer YOUR_KEY. Returns WAV audio.

Audexum speaks 32 languages.
