Generate SCARY Real Custom AI Voices!

MATTVIDPRO tests 11 Labs' Voice Design feature, which generates custom AI voices from text prompts. He creates a goblin, a Rick-like rant, a wise old monkey, and others, adjusting parameters like stability and exaggeration. The tool blocks copyrighted character voices and requires prompts of at least 100 characters.
Questions this video answers
Go to Voices → click Add a new voice → choose Voice Design.
At least 100 characters (UI enforces a 100-character minimum).
Stability, similarity, style, exaggeration.
No — the demo shows copyrighted character prompts (e.g., Rick) are blocked by the platform's prohibited-use policy; descriptive approximations may still be used.
Host notes 11 Labs has a public voice library that can pay voice owners when used, but observes it does not appear possible to upload Voice Design-generated voices himself (upload support for Voice Design voices is unclear).
Chapters
This is just the week that keeps on giving. Yesterday we saw seven, maybe eight large AI announcements, and today we have another one. Now, like I said, guys, I'm gonna try to get to everything eventually. I'm doing a larger AI news roundup video probably towards the end of this week, but I'm just doing, you know, full review videos of everything going down the list of what I find the most interesting. So this was announced today from 11 labs, which is the K of the text to speech AI arena. This is voice design. Generate a unique voice from any text prompt alone. Before, 11 labs did have a voice generator of its own, but it would kind of just make a random Voice. Or on 11 Labs, you could clone your voice. But this is promptable, this is direct, and I think you're gonna like the examples. Check this out.
Introducing voice design. Aha. Captain, set sail for adventure. Now you can create any voice simply by typing text description. Aye, lad, there's magic in these old bones yet. Or how about the voice of an angry ogre? Get out of my way if you know what's good for you. Or maybe you want a cute little sassy mouse.
Watch out, big world. I'm small, but I'm mighty.
Whether it's for videos, games, or any other project, voice design can help turn your ideas into reality.
I predict a great and powerful destiny for you.
So try out the new voice design today and show us what you create.
Like I said, Guys, 11 labs is the king. All of these voices are diverse. They sound real difficult to tell. It's AI and fun fact, guys, if you hear my voice anywhere online, whether it be, you know, YouTube shorts, a TikTok video, or an advertisement, it's probably someone using my voice on 11 labs because my voice is available to use on their voice library. Anyways, guys, let's dive in. So here is the voice designer. If you're wondering how you get there, on the 11 Labs website, you just go to voices, click add a new voice, and then go to voice design. So for the prompt, I'm going to do creepy, disheveled goblin. Very expressive and sly. Generate voice. Oh, you have to do at least 100 characters. There we go.
Hey, got any gold for this goblin? I need some goblin gold for my goblin hijinks. What? You don't have any? Loser.
Okay, I'm gonna be real. That does not sound like a creepy goblin. That just sounds like a dude voice 2.
Hey, got any gold for this goblin? I need some goblin gold for my goblin hijinks. What? You don't have Any loser?
Yeah. Okay, that's a little bit more goblin y. How about this one?
Hey, got any gold for this goblin? I need some goblin gold.
That sounds like the most average guy ever. All right, we gotta learn how to prompt this thing. I always think of goblins being high pitched. We'll say he's raspy, high pitched, slightly evil, man. It generates the voices really quick. I mean, it's just like an instant voice based on your prompt, which is really insane. Definitely haven't seen anything like this before. I don't think any other text to speech.
I got any gold for this goblin? I need some goblin gold for my goblin hijinks. What? You don't have any loser?
That's accurate, guys. That is a. That is a goblin right there. I love that.
Hey, got any gold for this goblin? I need some goblin gold for my goblin hijinks. What? You don't have any loser?
Okay, yeah, I'm already loving this guys. Voice 3.
Hey, got any gold for this goblin? I need some goblin gold for my goblin hijinks. What? You don't have any loser?
Yeah, that's a little bit more serious. That's like a voice I think would be like a video game. This is maybe like a children's story. And I would say this is probably like somewhere in the middle.
Hey, got any gold for this goblin?
That's like a good goblin goblin. Oh, I pressed escape. All right, well, there goes your voice. By the way, if you press escape, it just removes the whole thing. So don't accidentally press ESCAPE. 11 Labs. If there's anything, please just make sure that every time I press escape it doesn't delete my voices. It does not. Save your stuff when you go back. Alright, well, I guess goblin's gonna go. Let's try something else. A bountiful, expressive, heroic, commanding, confident voice. Let's take a listen.
Hello, travelers. I am the hero of this land. Have you seen any creepy lil goblin men walking around? I have him some gold and a. I think I got scammed.
Oh, I typed I have him some gold. No, I gave him some gold.
Hello, travelers. I am the hero of this land. Have you seen any creepy lil goblin men walking around? I gave him some gold and I think I got scammed. I love it.
He's so confident. Oh, this is just freaking awesome, man. It sparks my creativity to hear these voices. I'm not gonna lie. This is exciting. A voice for any need.
Hello, travelers. I am the hero of this land. Have you seen any creepy lil goblin men walking around? I gave him Some gold and I.
Think I got scammed. Oh, you can hear there's like a little bit of weirdness going on. Some of that AI generated like creep factor just waving its way through. It's like a high pitched screech almost.
Hello travelers. I am the hero of this land. Have you seen any creepy lil goblin men walking around? I gave him some gold and I think I got scammed.
Wow, that was really good. That was an impressive one. That sounds like a real person for sure. Also confident, also heroic, commanding. This one's I think probably like the most stereotypical like hero.
Hello travelers. I am the hero of this land. Have you seen this one?
Will be hero his value. What? I guess this would just be like the language he normally speaks. English, American accent, male save voice. There we go. And now it is just like a normal voice in your library. And if we use it. Oh, okay, sweet. So we actually do get all of our typical settings that we can mess with like stability, similarity, style, exaggeration.
I am a hero. I swear I just got scammed a couple of times. That goblin kept saying he would PayPal me for Bitcoin.
Oh man, I. I'm having too much fun. I'm a hero. I swear. That goblin just kept scamming me. Amazing. What if we use like characters Rick from Rick and Morty, for example. What happens? Alright, Grock 2 in fun mode just gave me something nice. Sorry. Looks like the prompt might violate our prohibited use policy. All right, all right. So obviously copyrighted stuff is blocked, but can we bring it out? Describe Rick's voice to me. Okay. No, Grok. I don't want Rick describing his own voice, but that's actually a decent description. So slap that in there. Decently deep male voice. Let's try it.
Oh, geez, Morty. You want to know what I think about ChatGPT? It's like. It's like a cosmic blender, Morty, mixing up a smoothie of human knowledge. But burp. Someone forgot to put the lid on. So it's just splattering half baked facts all over the place. And everyone's like, oh, look at this. It's AI. It's the future. But really it's just a glorified parrot with a thesaurus, Morty. It doesn't know quantum mechanics from a quantum lemon. But hey, at least it keeps the interdimensional cable interesting, right?
I don't know why the voice was so quiet there in the beginning. It kind of sounded decently accurate. Let's try voice two.
Oh, geez, Morty. You want to know what I think about CHAT GPT? It's like. It's like a cosmic blender, Morty, mixing up a smoothie of human knowledge. But this burpee, someone forgot to put the lid on.
This sounds like depressed half baked facts.
All over the place. Oh geez, Morty. You want to know what I think about ChatGPT? It's like. It's like a cosmic blender, Morty, mixing.
Up a smoothie of human knowledge. Yeah, it's like Rick from a different universe. It's kind of close though, I have to say, loud and ranty. I'd be interested to see how close you really can get.
Think about ChatGPT. It's like. It's like a cosmic blender, Morty, mixing up a smoothie of human knowledge. But. Oh geez, Morty, you want to know what I think about ChatGPT? It's like, it's like a cosmic blender, Morty, mixing up a smoothie of human knowledge. But burp, someone forgot to put the lid on. So it's just splattering half baked facts all over the place. And everyone's like, oh, look at this. It's AI. It's the future. But really it's just a glorified parrot with a thesaurus, Morty. It doesn't know quantum mechanics from a quantum lemon. But hey, at least it keeps the interdimensional cable interesting, right?
That's actually pretty decent. I mean it's by no means an exact clone, but for just describing what his voice sounds like from the TV show, that's pretty close. Alright, voice three.
Oh geez, Morty. You wanna know what I think about ChatGPT? It.
That's horrifying. Alright, voice two. Bam. Another one in the books. You know what I'm actually really interested in? Is it going to let me like make money off of this voice? Because if you guys didn't know, you can upload your voices into like the public library on 11 labs and when someone uses that voice, you get a cut of the money. It does not appear like we can actually upload the voices ourselves. Alright, let's get real funky. At the beginning of each sentence the voice is high pitched. At the end of each sentence it becomes low pitched. Alright, I'm gonna have it roast me.
In the realm of technology, where others conjure digital masterpieces. Matvid Pro's attempts at innovation.
Okay, it is not following the prompt supposed to be starting high pitched and then end up low pitched.
In the realm of technology where others.
Con in the realm of technology, where others.
Yeah, okay. I don't think that you can prompt it that specifically. It did not like this prompt. Alright, makes sense though. Makes sense. I mean, that was kind of a long shot. We're gonna do a comical deep Australian voice, slight rasp, speaking into high quality podcast mic. See if we can get like a higher quality sounding voice.
In the realm of technology, where others conjure digital masterpieces, Matved Pro's attempts at innovation.
Again, we have some of that glitching in the background. All right, Voice two. In the realm of technology, where others conjure digital masterpieces, Matt Vidpro's attempts at innovation are like watching a giraffe on roller skates. Hilariously awkward and bound to end with an ungraceful tumble. His latest sounds depressed. Man of technology. We have to make sure that you prompt it. Like excited, alive, enthusiastic, not boring, loud.
In the realm of technology, where others conjure digital masterpieces, Matved Pro's attempts at innovation are like watching a giraffe on roller skates. Hilariously awkward and bound to end with an ungraceful tumble. His latest venture into AI video generation. Let's just say even his AI suggested he might want to try something less challenging, like making toast.
I love how good Grok is at roasting me. You can also randomize. Oh, okay, so this is like the way that they want you to prompt it. Deep, gravelly New York accent, tough and world weary, often cynical. A hint of alien can be heard. Sure, a New Yorker. But he's from the New York on Mars. No, not an image generation. Really? What would he say though? Okay, perfect.
Hey, I'm walking here on red sand, but still you think traffic's bad in man. Hey, I'm walking here on red sand, but still you think traffic's bad in Manhattan? Try navigating through a dust storm with no visibility. And don't get me started on the coffee here. It's like they've never heard of a decent espresso. But hey, the view of the earthrise fugged about it. It's the best in the solar system. And talk about rent control. You wouldn't believe the space they give you out here for a New York minute of your earth time. But seriously, if I hear one more earthling ask if we've got pizza on Mars, I'm going to lose it. We got something better. We got freeze dried gelato, capiche?
Okay, I guess that's decent. Honestly, not much New York accent came through there. Strangely enough, if a strawberry. A Pixar character, small, cute, Dangerous. Write me a quick line about a strawberry convincing the court that the human was about to eat it.
Ladies and gentlemen of the jury, observe the evidence. A bowl of freshly picked strawberries, myself included, sat innocently on the table. The defendant, with a gleam in their eye and a salivating mouth, approached with intent to consume. My fellow berries can testify they heard the sinister spoon clinking, saw the nefarious napkin at the ready. I, the last unnibbled berry, narrowly escaped through a plea of, you can't possibly eat something this cute. But lo.
Ladies and gentlemen of the jury, observe. That just sounds like a woman.
Ladies and gentlemen of the jury, observe the evidence.
That sounds like it's in a courtroom. There is a lot of reverb in some of these. I wonder if you could just straight up prompt for reverb. Reverb. Reverb. Reverb. All right, sure.
In a reverb room, someone might sing or yell to hear their voice echo magnificently turning even the simplest. In a reverb room, someone might. In a reverb room, someone might.
Okay, you cannot just prompt for reverb. Figured that out. Deep, gargling, gravelly, rustic. Old. Cracking. Extremely deep. So old. I can't believe it. Gargantuan male voice. A wise old monkey tells me about why bananas are so good. It's just giving me, like, chatgpt facts about bananas.
Ah, gather round, young one, and lend an ear to this wise old monkey. For I shall impart the lore of the glorious banana. Banana. Bananas, my simian friend, are nature's own prepackaged wonder. Why, you ask, are they so good? Let me peel back the layers. Energy boost. Bananas are packed with. Ah, gather round, young one, and lend an ear to this wise old monkey. For I shall impart the lore of the glorious banana. Bananas, my simian friend, are nature's own prepackaged wonder.
Oh, my God.
Gather round, young one, and lend an ear to this wise old monkey. For I shall impart the lore of the glorious banana. Bananas, my simian.
This middle one is horrifying. Like actual demon the devil, but comically from a sitcom. All right, sure. It's giving me, like an actual script of the devil in a sitcom.
With a mischievous grin. Oh, come on, folks.
You think I invented the DMV line.
That was all humanity. But you gotta admit, I did spice it up with the take a number machine, didn't I? With a mischievous grin.
Oh, come on, folks. You think I invented the DMV line.
That was all humanity. But you gotta admit, I did spice.
It up with the take a number machine, didn't I?
With a mischievous grin. Oh, come on, folks. You think I invented the DMV line? That was all humanity. But you got.
I like this voice, but it's absolutely not supposed to sound like the devil, you know what I mean? This sounds like an actual, like, puffball. Now let's use this for what people are actually gonna do with it. Cute anime girl. Let's be honest, you simps are gonna be doing this.
Imagine we're all characters in a cosmic play where the script is both written and yet to be written. Here's the philosophical conundrum. If we are mere actors on this stage, then who or what is the audience? Is consciousness the universe experiencing itself? Or is it something more?
That's pretty close.
Imagine we're all characters in a cosmic play where the script is both written and yet to be written. Imagine we're all characters in a cosmic play where the script is both written and yet to be.
Yeah, that's all. Stereotypical anime voice. That's about exactly what I would expect. Big old grumpy volcano booming, huge voice. Volcano booming, huge voice. I love how.
