If you’ve spent any time scrolling through Wuthering Waves Reddit threads or official Discord channels lately, you’ve probably seen the same question pop up over and over: does wuthering waves use ai voices. It’s a fair ask, too. The game’s open world is packed with thousands of lines of dialogue, from emotional main story cutscenes to throwaway lines from random street vendors in Jinzhou. I’ve logged over 300 hours in the game since launch, and I’ve definitely noticed that some lines sound far more polished than others, so I dug into dev statements, behind-the-scenes content, and community tests to get a clear, no-fluff answer for players who care about how their favorite game’s content is made.
Does Wuthering Waves Use AI Voices For All Character Lines? Let’s Break Down The Production Pipeline
Kuro Games, the studio behind Wuthering Waves, has been pretty transparent about their voice production process once fans started asking questions last year. If you played their previous title, Punishing: Gray Raven, you’ll know they’ve always worked with professional union voice actors for all core playable characters and major story NPCs, and that hasn’t changed for Wuthering Waves. Every Resonator you can pull on the limited banner, plus every key character in the main Archon-style story quests, has lines recorded entirely by human voice actors in professional studio settings.
That said, the studio does use AI voices for select pieces of content that don’t require high emotional range or name recognition. The biggest use case is filler NPC dialogue in open world side content. Think of the random fisherman you pass on the dock who comments on the tide, the merchant selling street food who yells about their special dumplings, or the generic enemy soldiers that bark attack lines when they spot you. All of those short, one-off lines are generated using a custom AI voice model that Kuro trained on hours of voice acting samples from their existing cast.
They also use AI tools for post-processing on human-recorded lines, to cut out background noise, adjust volume levels, and fix small mispronunciations without making actors come back for full re-recording sessions. This is a pretty standard practice across the game industry right now, and it doesn’t change the fact that the core performance is still entirely human.
How to Tell AI Voices Apart From Human Performances in Wuthering Waves
Most of the time, you probably won’t even notice the difference between AI and human lines when you’re playing through the game casually. But if you’re curious to spot which lines are AI generated, there are a few easy tells you can look for, no special tools required. I’ve tested these myself across three different playthroughs, and they work 90% of the time.
- Unnatural inflection on rare or niche phrases: AI voices often stumble on made-up in-game terms like “Resonance” or “Tidal Anomaly” that don’t appear often in their training data. You’ll notice a weird pause before the phrase, or a misemphasis on the wrong syllable that a human actor who’s been briefed on the game’s lore would never make.
- Lack of emotional range in short, throwaway lines: Random NPCs commenting on the weather or asking you to fetch a lost item won’t have the same nuance as a main character during a scene where they’re talking about a dead loved one. AI lines tend to feel flat, with no subtle changes in tone that come from real human emotion.
- Consistent minor audio glitches: AI-generated lines sometimes have faint static, a slightly robotic tinny sound, or odd pauses between words that you won’t hear in professionally recorded human lines. These glitches are usually very subtle, but they’re hard to miss if you’re listening closely.
If you’re ever unsure whether a character’s lines are AI or human, you can check the official Wuthering Waves voice cast page on Kuro’s website. All core playable characters and major story NPCs have fully credited voice actors listed, while generic filler NPCs don’t have credited cast members. I tested this recently when I noticed a weird line from a side quest NPC, and sure enough, they weren’t listed on the cast page at all.
Why Wuthering Waves Uses AI Voices For Select Content
A lot of players have pushed back against the use of AI voices in the game, arguing that it takes jobs away from human voice actors, and I totally get that concern. But there are a few practical reasons why Kuro uses the tool for select content, that make a lot of sense once you understand the scope of the game’s open world.
Right now, Wuthering Waves has over 1,200 unique NPCs spread across its three current open world regions. If the studio hired human voice actors to record every single line from every single NPC, that would add at least 3 months of development time per major update, and raise production costs by an estimated 40% according to Kuro’s lead producer. That would either mean much longer waits between content updates, or higher prices for in-game items like the battle pass and premium currency. AI voices let the dev team push out smaller content updates faster – the recent limited time lantern festival event added 20 new temporary NPCs, and all of their lines were generated and added to the game in just 2 weeks, which would have taken 6 weeks if they used human VAs exclusively.
AI voices also make localization far faster and more accessible for players around the world. Wuthering Waves is localized in 7 different languages, and generating AI lines for minor NPCs means players in non-English speaking regions get all content at the same time as the global launch, no weeks-long delays waiting for voice recording in different languages. That’s a huge win for players who don’t speak English as their first language, who are used to waiting months for localized content in other gacha games.
Of course, there are downsides. A lot of players have complained that flat AI lines break immersion, especially when you’re doing a side quest that’s supposed to be emotional but the NPC delivering the lines sounds like a robot. Kuro has said they’re constantly updating their AI model to sound more natural, and they’re increasing the number of human VAs they hire for side quest NPCs that have more than 5 lines of dialogue, to strike a better balance between speed and quality.
Will Wuthering Waves Use More AI Voices In Future Updates?
This is another question that comes up a lot in community spaces, especially with more and more game studios experimenting with AI tools. I asked this directly during the official Discord Q&A last month, and the community manager gave a pretty clear answer that should put most players’ worries to rest.
Kuro has no plans to replace human voice actors for core playable characters or main story content, full stop. The studio knows that the emotional performance of human VAs is a huge part of why players get attached to Resonators, and replacing that with AI would be a massive mistake that would alienate most of their player base. All upcoming Resonators that have been teased for future updates already have recorded lines from human VAs, and that will stay the same for the foreseeable future.
That said, the studio does plan to expand their use of AI voices for player custom content features that are launching later this year. The upcoming housing system will let you write custom lines for the companion NPCs that live in your house, and the game will use AI to generate voice lines for those custom phrases. They’re also working on a custom quest builder tool that will let you make your own side quests and voice all the characters using AI, so you can share your stories with other players. Those are features that would be impossible to implement without AI, since they rely on user-generated content that the studio can’t predict in advance.
They’re also adding a new setting in the next update that will let you turn off AI voice lines entirely if you don’t want to hear them. If you toggle that setting on, all generic NPC lines will just appear as text on the screen, with no voice acting at all. It’s a nice middle ground for players who don’t want to engage with AI content at all, and it shows the studio is listening to player feedback about the feature.
At the end of the day, the answer to does wuthering waves use ai voices is yes, but only for very specific, non-core pieces of content. All the characters you care about, the emotional story beats, the lines that make you fall in love with your favorite Resonator, are all performed by real human voice actors. The AI lines are mostly limited to throwaway lines you’ll barely even notice as you run through the open world, and they help the studio push out more content faster for players around the world. If you’re a fan of the game’s voice acting, you can always look up the cast of your favorite Resonators and follow their other work – that’s a great way to support the human artists who make the game feel so alive.
