Are these voices Brazilian or European Portuguese?

The recordings on this page use Brazilian Portuguese, labelled pt-BR. Felipe and Alice demonstrate that variety. These samples do not demonstrate European Portuguese. If your audience is in Portugal, test a suitable voice with locally reviewed wording before choosing it.

How should I prepare a Brazilian Portuguese script?

Write the words your audience would use in conversation. Include names, prices in reais, dates, and abbreviations in your test passage. For support calls, try both a brief answer and a longer explanation. Listen to the full sentence to check pronunciation and pacing before generating the rest of your script.

Which voices can I try for Portuguese text to speech?

The recorded examples on this page use Felipe and Alice. Select an example to hear its script, then replace the text to test that voice with your own words. You can explore more voices in Cartesia Playground .

What is Portuguese text to speech?

Portuguese text to speech converts a written script into spoken audio. You can use it for narration, accessibility, product interfaces, and the spoken responses of a voice agent. Speech generation does not translate the script or decide what an agent should say.

How do I choose a text-to-speech API for Portuguese voice agents?

Compare pronunciation, response time, streaming support, and output formats using the same scripts and playback setup. Include interruptions, short replies, and longer passages from your actual workflow. Have fluent Portuguese speakers review the voices before choosing one.

How do I build a voice agent that speaks Portuguese?

Combine speech recognition, conversation logic, and text to speech, or use Managed Agents to bring those parts together. Choose a voice, connect the tools your workflow needs, and test real conversations with fluent speakers. Define when the agent should ask for clarification or hand the conversation to a person.

What affects latency for Portuguese text to speech?

Time to first audio depends on the model, request, network connection, and client playback. A voice agent also includes speech recognition and response-generation time. Measure the complete conversation in your deployment; measure time to first audio separately from the time a caller waits for an answer.

How should I handle numbers, dates, and addresses in Portuguese?

Test the formats your users will hear, including local dates, prices, phone numbers, and addresses. Write ambiguous values in the form you want spoken and review the generated audio. Names, abbreviations, and regional conventions deserve a separate pronunciation check.

How do I integrate Portuguese speech into my application?

Send your script, model, language code, voice ID, and output settings to the speech API from your server. Keep API credentials on your server. Start with the text-to-speech API , then add playback, cancellation, and error handling in your application.

What audio format should I use for Portuguese speech?

Sonic offers output settings for browser players and telephony. Choose a container, encoding, and sample rate that your player accepts. The text-to-speech API reference lists the supported combinations. Match these settings to your phone provider when generating call audio.

Can I use Portuguese speech in IVR and phone systems?

You can connect generated speech to a telephony application. Configure the output to match your provider's audio requirements and test it over real calls. Your application still controls call routing, caller verification, interruptions, and transfers to a person.

What should I evaluate before an enterprise deployment?
