AI voice agents · Autessa Phone & Texting
English and Spanish voice agents
Autessa Phone & Texting supports bilingual AI voice agents in English and Spanish. One agent can have both languages, each with its own voice, greeting, extra instructions, filler phrases and error message, and the call switches to Spanish or English when the caller starts speaking it.
The problem it solves
Half your callers may not want English
A single-language agent forces Spanish-speaking callers to struggle or hang up, and running two numbers or two agents is hard to keep in sync. A bilingual agent answers on one number and meets each caller in the language they speak.
What you get
- AI voice agents understand English (US and UK) and Spanish (US and Spain).
- Each language has its own voice, greeting of up to 500 characters and extra instructions of up to 4,000 characters.
- Each language has its own filler and long-wait phrases (up to 10) and its own error message.
- The call switches once, on the caller's first phrase of three or more words in another configured language.
- Built-in filler lines exist in English and Spanish.
- A number's own speech language can be set wider for menus, ringing people and voicemail, even where the AI does not understand callers.
