I developed voice agents for multiple use cases in Retell AI. It is easy to develop and test these voice agents in Retell AI. The docs are very good and easy to understand. The most liked feature is to connect the voice agent to my custom n8n functions.

This is by far the best voice agent tool in the space. They key, like all AI is understanding how to prompt your agent to sound as human as possible. Learn this and it will change your life.
