Listen to the Style Feature in Action! Tips and Techniques for Voice Styling
Now let's explore what kinds of expressions you can create with the new AI voice's style feature, along with tips and techniques!
It's very easy to do, so give it a try yourself.
1. Emotional Expression Samples & Voice Styling Tips
Let's start with emotional expressions: joy, anger, sadness, and delight.
Adding emotional expression is very easy.
Simply write a style like "Read in a happy tone" or "Read in a sad tone"—that's all it takes.
The sample audio uses the voice "Ellis."
Audio sample with the style instruction "Please read in a happy tone."
I'm so happy! Thank you so much!
Audio sample with the style instruction "Please read in an angry voice."
Do you even understand why I'm angry?
Audio sample with the style instruction "Please read in a sad tone."
That's... that's so cruel.
Audio sample with the style instruction "Please read in a cheerful tone."
Come on! Let's go ride that rollercoaster next! It's going to be amazing!
2. Acting & Voice Character Samples & Voice Styling Tips
Ondoku's new AI voice can do more than just basic emotions—it can deliver nuanced, human-like performances!
Depending on how you write your style instructions, you can shape the voice into a variety of different characters.
Audio sample with the style instruction "Please read in an authoritative voice."
Hello, I'm Ondoku. I sound much more natural and human now!
Voice: Ellis
Voice: Ash
Audio sample with the style instruction "Please read in a whispery voice."
Hello, I'm Ondoku. I sound much more natural and human now!
Voice: Ellis
Voice: Ash
Audio sample with the style instruction "Please read in a confident and bright voice."
Hey there, I'm Ondoku! I've got the most natural, most human-like voice in the universe!
Voice: Ellis
Audio sample with the style instruction "Please read in an unconfident, hesitant voice."
Hello, I'm Ondoku. I sound more natural and more human-like now... I think...
Voice: Ellis
3. Using a Female Voice to Create a "Young Boy's Voice"—A Voice Styling Technique
One unique technique made possible by Ondoku's more natural-sounding AI voice is creating a "young boy's voice."
In animation, pre-adolescent boy characters are often voiced by female voice actors.
With Ondoku's new AI voice, you can do the same—select a female voice and give it a style instruction to produce a boy's voice.
The sample audio uses the voice "Ellis."
Audio sample with the style instruction "Please read in the voice of an energetic young boy."
Hello, I'm Ondoku. I sound much more natural and human now!
Additionally, the tone of the written text itself also affects how the voice sounds.
Audio sample with the style instruction "Please read in the voice of an energetic young boy."
Hey! I'm Ondoku! I sound way more natural and totally human now!
4. Age Styling Isn't Just for Kids—Tips for Reading in an Elderly Voice
Of course, you're not limited to children's voices—you can also have the AI read in an aged, elderly voice.
Audio sample with the style instruction "Please read in a grandmother's voice."
Hello, I'm Ondoku. I sound much more natural and human now!
Voice: Ellis
Audio sample with the style instruction "Please read in a grandfather's voice."
Hello, I'm Ondoku. I sound much more natural and human now!
Voice: Ash
Beyond descriptions like "grandmother" or "grandfather," you can also specify a particular age for the performance.
Audio sample with the style instruction "Please read as if you were 60 years old."
Hello, I'm Ondoku. I sound much more natural and human now!
Voice: Ellis
Audio sample with the style instruction "Please read as if you were 80 years old."
Hello, I'm Ondoku. I sound much more natural and human now!
Voice: Ellis
5. Tips for Creating Character Voices—Techniques for Creative Projects
What's more:
By getting creative with how you write the style instructions, you can produce even more advanced character performances.
Audio sample with the style instruction "Please read in a Valley girl voice."
Like, hi there! I'm Ondoku! My voice is, like, totally natural and super human-like now!
Voice: Ellis
Audio sample with the style instruction "Please read in the tone of a distinguished professor."
Today, we will discuss the complexities of quantum mechanics and the nature of time.
Voice: Ash
Audio sample with the style instruction "Please read in the tone of a police officer."
You have the right to remain silent. Anything you say can and will be used against you in a court of law.
Voice: Ash
6. Combine Acting, Age, and Character Styles—Of Course You Can Mix and Match!
Of course, you can also combine the different styling options we've introduced so far:
- Emotions
- Acting
- Age
- Character
You can combine these styling instructions for even more expressive results!
The sample audio uses the voice "Ellis."
Audio sample with the style instruction "Please read in the voice of an energetic young boy, sounding happy."
Yes! I won! I actually won!
Audio sample with the style instruction "Please read in the voice of an energetic young boy, sounding sad."
Aww man, I've had enough of this...
Audio sample with the style instruction "Please read in a Valley girl voice, sounding happy."
You're not so bad after all. Thanks!
Audio sample with the style instruction "Please read in a Valley girl voice, sounding angry."
You are, like... seriously the worst.
Audio sample with the style instruction "Please read in the voice of an 80-year-old, sounding happy."
It was all worth it, living this long.
Audio sample with the style instruction "Please read in the voice of an 80-year-old, sounding sad."
I see. That is truly unfortunate.
7. Reading with Accents and Dialects Using the Style Feature
In addition to acting, age, and character expressions, Ondoku's more human-like new AI voice can also read with regional accents and dialects!
The sample audio uses the voice "Ellis."
Audio sample with the style instruction "Read cheerfully with a British English accent."
Hello, I'm Ondoku. I sound absolutely brilliant and much more natural now!
8. The Style Feature Makes Foreign Language Reading Easy Too!
Ondoku's new AI voice can naturally read aloud not only in English but also in languages from around the world.
An important tip: when reading in a foreign language, write the style instructions in that language as well. For example, when reading in Spanish, write the style in Spanish.
Here's an example of speech synthesized in Latin American Spanish and European Spanish.
The sample audio uses the voice "Ellis."
Audio sample with the style instruction "Habla alegremente con acento latinoamericano."
Hola, soy Ondoku. Mi voz ahora suena mucho más natural y humana.
Audio sample with the style instruction "Habla alegremente con acento castellano."
Hola, soy Ondoku. Mi voz ahora suena mucho más natural y humana.
Of course, even when reading in a foreign language, you can specify accents and dialects.
For example, here's how it sounds when reading in Parisian French versus Quebec French.
The sample audio uses the voice "Ellis."
Audio sample with the style instruction "Parlez joyeusement avec un accent parisien."
Bonjour, je suis Ondoku. Ma voix est devenue beaucoup plus naturelle et humaine.
Audio sample with the style instruction "Parlez joyeusement avec un accent québécois."
Bonjour, je suis Ondoku. Ma voix est devenue beaucoup plus naturelle et humaine.
As you can see, the cutting-edge AI speech synthesis engine lets you read in many languages with ease!
Try experimenting with different voice styling techniques in languages other than English, too.
