### Answer To ensure your agent says numbers correctly, like "$4500" as "four thousand five hundred dollars," you could adjust the text processing within your assistant's configuration. While specific instructions on text preprocessing for numerical values in speech aren't directly provided in the documents, you might consider implementing custom logic in your application that formats numbers to their spoken equivalents before sending the text to your Vapi assistant for speech synthesis.
