Why companies choose Soniox for Portuguese
The hard parts of voice AI in production are mixed languages, exact details, and live conversation.
One vendor for the voice stack
Portuguese speech-to-text, text-to-speech, and translation share one API and one provider. Fewer integrations to build and fewer vendors to review.
Portuguese mixed with other languages
People switch between Portuguese and English or other languages mid-sentence. Soniox follows the switch in both transcription and speech generation, with no configuration.
Names, numbers, and codes
Phone numbers, IDs, email addresses, and codes in Portuguese are transcribed exactly as spoken and read exactly as written.
Built for live conversation
Speech-to-text streams Portuguese words as they are spoken, and text-to-speech starts audio from the first few words of text.
Voice AI API platform for Portuguese markets
Keep Portuguese audio and transcripts in the region your customers and regulators require.
In-region processing
Available regions: US, EU, Japan, India. Audio and transcripts stay in the region you choose, for both processing and storage.
