Cast text to speech voices for every anime character: hero, rival, villain, mentor, narrator, and sidekick. Voice picks, line direction, real costs, and limits.
An anime character voice generator turns a character's lines into speech. The hard part is not the generation. It is giving every character in a cast a voice that fits who they are and does not sound like anyone else in the scene.
This guide shows how to do that with text to speech in MkAnime. It maps common anime roles (the hot-blooded hero, the cool rival, the villain, the mentor, the narrator, the comic sidekick) to voices that exist in the library today, explains how to direct each line, and states plainly what it costs and what it cannot do.
MkAnime's AI Anime Voice Generator (in the Tools menu) turns one block of text and one voice into one audio file:
You can open it directly in the voice generator workspace once you are signed in.
When this guide was written (October 2026), the public voice library had 470 voices. English has the largest set: 56 male and 49 female voices. Most English male voices are tagged young adult (37), 16 are tagged middle-aged, and a few are tagged child, such as Teen Boy and Kindergarten Boy. Other languages have their own casts, for example 12 male and 12 female voices in Japanese, 22 male and 29 female in Korean, and 17 male and 20 female in Mandarin Chinese.
Every voice comes with a short description of its tone, such as "Slightly Husky, Tight and Powerful, Hot-blooded Anime Protagonist Vibe". Those descriptions are the fastest way to cast. The library is live, so the exact list can change; search a role word like "hero", "villain", or "narrator" to see what is there now.
Before you open the picker, write one line per character: age range, attitude, and volume. "Loud, reckless 17-year-old hero" and "calm, cold rival who never raises his voice" point to very different voices.
Then decide how each voice should contrast with the others in the same scene. Two characters who share a scene should differ in at least one of these: pitch (deep or bright), pace (fast or slow), or texture (clean or husky). If two voices only differ in name, viewers will mix them up.
Here is a starting map from the current English library. Play the samples and keep two or three per role.
| Anime role | English voices to try | What to listen for |
|---|---|---|
| Hot-blooded hero | Strong-Willed Boy, Determined Man, Passionate Warrior | Tight, powerful, rising energy |
| Cheerful best friend | Energetic Man, Lively Man, Decent Boy | Bright and easygoing |
| Cool or teasing rival | Decent Young Man, Reserved Young Man | Relaxed, a little distant or lazy |
| Villain or dark lord | Deep-toned Man, Bossy Leader, Man With Deep Voice | Deep, slow, dramatic tension |
| Brute or monster | Goblin, Angry Pirate, Friendly Giant | Gritty, heavy, rough |
| Mentor or old master | Captivating Storyteller, Gentle Teacher, Deep-voiced Gentleman | Composed, warm, unhurried |
| Kid or younger brother | Teen Boy, Kindergarten Boy | Light, fast, youthful |
| Comic sidekick | Comedian | High, exaggerated swings in pitch |
| Robot or AI companion | Lucky Robot | Even, mechanical precision |
| Narrator or episode preview | Expressive Narrator, Movie Narrator, Terror Story Narrator (for horror) | Clear, dramatic, carries a whole paragraph |
For female characters, the same method works with the 49 English female voices; set the gender filter to female and search for words like "girl", "lady", or "queen". MkAnime also has a separate guide on anime girl voices with its own casting map.
If your characters speak Japanese, the Japanese library has role-style voices too, such as Loyal Knight, Serious Commander, Gentle Butler, Optimistic Youth, and Sporty Student. Japanese voices read Japanese text, so write those lines in Japanese.
Give every shortlisted voice the same test line, one that has a question, a pause, and an exclamation:
"You came all this way... just to lose? Then get up and fight!"
Pitch is fixed per voice, so the character comes through in how the line is written and directed:
Each generation is one voice, so a conversation is built line by line:
The AI anime dubbing guide covers the rest of the workflow, from keeping voices stable across episodes to multilingual versions.
Use these voices for your own characters and scripts. Do not try to imitate a real voice actor or recreate dialogue from a published anime.
The best one is the one whose voices fit your cast and can stay consistent across episodes. In MkAnime, you pick from 470 library voices with role descriptions, set emotion and speed per line, and download MP3 files. Play the samples for each role before you generate.
Yes. Start with Deep-toned Man, Bossy Leader, or Man With Deep Voice, write slow lines with ellipses, and try 0.9× speed. Use the whisper emotion for quiet threats and angry for outbursts.
Playing voice samples is free. Generating audio uses credits (1 credit per 100 characters when this was written), and credits come with a paid plan. There is no free daily allowance.
Yes. Generating audio needs a signed-in account, and each generation uses that account's credits.
No. Each generation uses one voice. Generate each character's lines separately and put them together in your editor.
Yes. Download the MP3 and use it with AI anime lip sync, import it into your editor, or use the AI Dubbing tool to replace the audio of a short clip.
