Vapi has introduced a new feature called Call Analysis, which allows users to summarize, evaluate, and extract valuable insights from their voice assistant calls. This feature uses customizable JSON schemas to extract structured data, evaluates call success based on predefined criteria, and generates concise summaries for quick review. With Call Analysis, developers can unlock valuable information from their voice assistant calls and use it to improve their assistants' performance and overall user experience. The feature offers several key benefits, including data collection and integration, performance assessment, and time-saving summaries. To set up Call Analysis, users can configure settings using the API or SDK, such as structured data schemas, success evaluation prompts and rubrics, and summary prompts. The Vapi team provides detailed documentation to help users get the most out of this powerful new feature.
