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 10,000 char/month free plan — 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 supports 33 languages.
Switch language with one parameter — same API endpoint, same pricing.
See the full 33-language list in the API docs or on the multilingual TTS guide.
