Google has introduced a new feature called Audio Overview in its AI note-taking app, NotebookLM, that transforms documents, notes, and other materials into podcast-style audio discussions between two AI hosts. This feature, which builds on Google’s Gemini AI model, aims to make research more engaging by summarizing material, making connections between topics, and adding a conversational tone. However, it is currently limited to English, can sometimes generate inaccurate information, and takes time to process larger files. Despite these limitations, Google is excited about the potential for improving learning and retention through audio. The feature is still experimental, and users cannot yet interact with the AI hosts during the discussion. Google's innovative approach reflects the growing interest in audio content, with podcast listenership expected to reach over 504 million people globally this year.
