How to Add Custom Music or Dialogue in Veo 3: A Complete Guide
Introduction
Google Veo 3 has rapidly become one of the most powerful AI video generation tools available in 2025. Its ability to create stunning, cinematic videos from simple text prompts, complete with native audio like music, sound effects, and dialogue, offers creators unprecedented creative freedom. However, many users want to go beyond Veo 3’s built-in audio options and add their own custom music or dialogue to truly personalize their videos. This guide will walk you through how to effectively add custom audio elements to your Veo 3 videos, whether you’re a content creator, marketer, educator, or freelancer.
Understanding Veo 3’s Native Audio Capabilities
Before diving into custom audio, it’s important to understand Veo 3’s native audio features. Veo 3 can generate synchronized music, sound effects, and even character dialogue directly from your prompts. It supports over 40 multilingual voices with natural lip-syncing, which makes it easy to create videos with built-in narration or conversations. However, the native audio is generated based on your text prompt and style instructions, which means it might not always perfectly match your vision or brand’s unique sound.
Why Add Custom Music or Dialogue?
- Brand Consistency: Use your own music tracks or voice actors to maintain a consistent brand identity.
- Creative Control: Customize tone, pacing, and emotion beyond AI-generated audio.
- Licensing and Rights: Use licensed or royalty-free music you own or have permission to use.
- Higher Production Value: Professionally recorded dialogue or music can elevate your videos.

Review the final output to ensure audio sync and quality meet your standards.
Tips for Writing Prompts to Complement Custom Audio
