# How to Create Marketing Voiceovers with ChatGPT

ChatGPT combines script refinement with voice generation in one conversation. Describe the mood and audience for your ad, let ChatGPT polish the script for spoken delivery, then generate the audio with different energy levels. The creative brainstorming approach helps you find the right voice and delivery before committing.
