By default, knowledge bases are optimized for English content. If your documents are in non-English languages (Hindi, Spanish, French, etc.) or you need cross-lingual retrieval (e.g., query in English, retrieve from Hindi documents), enable Multilingual language support when creating a knowledge base.
Choose the language support mode before uploading. Existing knowledge bases cannot be switched between default and multilingual — you’ll need to create a new one.
If your agent handles calls in multiple languages using multilingual voice support, pair it with a multilingual knowledge base for consistent cross-lingual performance.
