Why should I use Dialogue Waves instead of Play Sound for voice acting & localization?

Hi everyone,

I am currently working on a solo indie game project (a first-person psychological horror game). As I move into the localization and voice-over stage, I am trying to build a clean and scalable pipeline for my game’s dialogues.

Initially, I was thinking of managing audio files with standard Play Sound 2D / Play Sound at Location nodes and changing the files dynamically based on the current culture. However, I’ve recently learned about Dialogue Voices and Dialogue Waves and how they integrate into the Localization Dashboard.

As a solo developer, I want to avoid messy Blueprint logic (like using massive Switch-on-Culture systems for every single dialogue line).

Could experienced developers explain the core benefits of switching to the Dialogue Wave system instead of traditional sound nodes?

Specifically, I would love to know:

  1. How does it improve automatic subtitle management and senkronization?

  2. How does the asset redirection mechanism work seamlessly behind the scenes when changing cultures?

  3. In terms of long-term scalability (adding 5+ languages later), does it actually save time despite the initial setup complexity?

Thanks in advance for your insights and advice!
