If a caller speaks Spanish and the AI responds in Spanish, the transition from Spanish to English is currently considered normal behavior in a multilingual setup, since English is configured as the primary language. One way to prevent this would be to set Spanish as the only language with no secondary language; however, the client has declined this option. Given the current configuration—English as the main language and Spanish as the secondary language—is it possible for the AI to continue the conversation entirely in Spanish once the caller begins speaking Spanish, and maintain that language consistently until the call is transferred? At present, the AI switches from Spanish to English during the transfer, which may disrupt the user experience.
