Spanish speech synthesis for production voice apps
Spanish is spoken by more than 500 million people across Spain, Mexico, Colombia, Argentina, Peru, Venezuela, Chile, and beyond. If your voice agent, IVR, or narration product speaks to them, text-to-speech has to get the details right: phone numbers and codes read exactly as written, names pronounced the way Spanish speakers expect, and text that mixes Spanish with English spoken in one voice.
Soniox TTS generates Spanish speech over a real-time WebSocket, starting audio from the first few words, or with a single REST request, through one multilingual API built for 60+ languages. Every voice speaks Spanish, you can clone your own voice, mix languages in one sentence, and get character-level timestamps.
