Voice is quickly becoming one of the most exciting frontiers for new software builders. OpenAI spotlighted how Retell AI uses their models to handle massive voice traffic, showing just how dependable real-time conversational AI has become.

For anyone building web apps with AI coding assistants, voice capabilities are no longer out of reach. What used to require complex telecom infrastructure and custom speech pipelines can now be connected to your project with standard APIs.

If you are planning your next build in tools like Lovable, Bolt, or Cursor, consider whether adding conversational voice could make your app stand out. From customer support bots to interactive learning tutors, automated phone calls and voice interfaces are practical features you can prototype today.
