Sofia, a native Spanish platform voice, reads the playground above. Any Sonex Labs voice can also read Spanish, keeping its own accent, and a voice cloned from a 10-second recording of a Spanish speaker carries that speaker's accent.
Sign up free, then send Spanish text to the API with "output_format": "mp3" and save the file, or generate clips in the dashboard and download them. Scripts longer than the playground's 220 characters work the same way.
Paste up to 220 characters of Spanish here to have it read out loud; sign up to read longer text through the dashboard or the API. Write currencies in words when "$" could mean pesos or dollars, and spell out abbreviations such as "Ud." and "Sra.".
About Spanish
Spanish has one written standard and many spoken ones. Spain says vosotros and distinguishes the "th" in gracias; most of Latin America uses ustedes and seseo. Argentina, Uruguay and much of Central America use vos instead of tú ("¿vos querés?"). A call script also has to choose between tú and usted: banks and clinics in Mexico or Colombia usually say usted, while many brands in Spain tutean their customers. The samples on this page include both, read by Sofia, a native Spanish platform voice, and the playground opens with a usted reminder.
Spanish is also the second language of US customer service. A caller in Los Angeles or Miami may switch between English and Spanish in one sentence ("le mandamos el tracking number por text"). Pāṇini reads Spanglish in one voice, and the same voice can answer the English-only caller next, at the same price.
Use cases
Lenders and fintechs in Mexico, Colombia and Peru remind customers of due dates in a polite usted register.
Insurance, healthcare and utility lines answer Spanish, English and Spanglish callers with the same voice.
Couriers, clinics and telecoms confirm slots and visits with customers across Spain.

YouTube
Yes, AI voices are allowed. What YouTube limits is mass-produced, repetitive content: videos made from a template with little original work. Its July 2025 update renamed that rule from “repetitious” to “inauthentic” content (YouTube’s monetisation policies).
Write your own script, add your own research or editing, and keep one consistent voice for the channel. Where a realistic AI voice could mislead viewers, use YouTube’s altered or synthetic content label. The monetisation decision is always YouTube’s.
Voice cloning
Clone your voice from a 10-second recording. Your clone speaks Spanish, and every other language Pāṇini supports, in your own voice. The language comes from the text you type, so a clone recorded in English or Hindi can read a Spanish script.
Your accent comes with it: a clone sounds like you speaking Spanish, not like a different native speaker. Every free account includes one voice clone. Clone only your own voice, or a voice whose owner has agreed.
API
One request returns Spanish audio as MP3. The language is detected from the text, so no language setting is needed. Pāṇini TTS starts streaming audio in under 200 ms (time to first byte).
