Portuguese text-to-speech API: voices, example and limits

Generate Portuguese speech from text over plain HTTP: 2 live voices, no setup beyond an API key. The Portuguese voices are described in the API as Brazilian Portuguese, one female and one male.

Status: every non-English result is marked native_review_pending until a native speaker approves the language. Treat the audio as unreviewed for anything customer-facing and have a native speaker listen before you ship it.

Hear the library

The library holds 30 checked Portuguese clips for the live voices (short words and phrases). Press to play:

Speak a sentence

Anything outside the library is generated live. Our test sentence (Portuguese, voice pf_dora) took 7.4 seconds on 2026-10-08 through the public demo endpoint (one observation, no GPU worker on this path; do not treat it as a benchmark).

cURL

curl -X POST https://speakvora.com/api/v1/speak \
  -H "x-api-key: $SPEAKVORA_KEY" -H "content-type: application/json" \
  -d '{"text":"Seu pedido está pronto para retirada.","voice":"pf_dora","lang":"pt"}'

# 200 {"url":"...","lang":"pt","voice":"pf_dora","format":"mp3","live":true,"review_status":"native_review_pending"}

Write numbers as words

Outside English, digits are rejected. We tested this: Seu pedido número 12 está pronto. returns invalid_text. Write the number out instead: Seu pedido número doze está pronto.. Remove placeholders such as (name) too.

Limits and honest notes

1 to 500 characters per request; the language you send must match the voice.
Live generation for this language runs on the standard lane in our tests; library clips and repeats are quick.
Your own voice is not offered in Portuguese except where noted above; use a catalog voice.
Billing is per character at $0.70 per million for catalog voices, same as English. A non-Latin character counts as a character.

Is Portuguese speech reviewed by a native speaker?

Not yet. Results carry review_status native_review_pending. English is our reference language.

Can I use my own voice in Portuguese?

Custom voices support English, with French and German in beta. Spanish, Hindi, Chinese and Japanese were not intelligible in testing and are not offered.

How do I pick the language?

Send lang as an ISO code (for example pt) and a voice from that language. Mixing a voice and a different language is rejected.
