[Emotional Expression] Next-Generation AI Voice Settings (Reading Style, Quality, Speed, Pitch)

The settings you can configure and adjust include:

• Reading Style

Let's explain each setting.

Reading Style | You Can Now Freely Specify Styles and Emotional Expression!

The biggest update in these next-generation AI voices is the ability to freely specify reading styles!

You can specify the reading style in this section of the new voice reading page.

Styles can be specified in two ways: pre-registered options and a free-text input box.

How to Specify Style from Pre-Registered Options

First, let's look at how to select a reading style from pre-registered options.

There are 6 options registered in the dropdown menu:

• News Style
• Narration
• Cheerful
• Calm
• Business
• Storytelling

When you need to quickly generate audio for video production, language learning materials, or in-store narration, simply select a reading style from these options.

Voice Samples for Each Reading Style (English)

The voice used is "Ellis."

Voice sample read in "News Style"

Voice sample read in "Narration"

Voice sample read in "Cheerful"

Voice sample read in "Calm"

Voice sample read in "Business"

Voice sample read in "Storytelling"

How to Specify Style and Emotional Expression with Free-Text Instructions

What's more!

You can now freely describe and specify reading styles to match your purpose and content.

To specify a reading style, write your instructions in the "Reading Style (Optional)" text box.

For example, you can have text read aloud with rich emotional expression like this.

All samples are read using the "Ellis" voice.

Voice sample with instruction "Please read in a whispering voice"

Hello, I'm Ondoku. I sound much more natural and human now!

Voice sample with instruction "Please read as if you were 80 years old"

Hello, I'm Ondoku. I sound much more natural and human now!

Voice sample with instruction "Please read with a British accent"

Hello, I'm Ondoku. I sound much more natural and human now!

As you can see, you can now read aloud in a much wider range of styles than ever before!

Adjusting Reading Speed and Pitch (Voice Height)

On Ondoku's new reading page, you can also adjust reading speed and pitch (voice height).

Reading speed can be adjusted in 5 levels:

• Very Slow (0.5x)
• Slightly Slow (0.75x)
• Normal (1x)
• Slightly Fast (1.25x)
• Very Fast (1.5x)

This allows for various expressions, such as using slower audio for language learning and shadowing, or faster audio for entertainment videos.

Also, pitch (voice height) can be adjusted in 5 levels:

• Very Low (-1)
• Slightly Low (-0.5)
• Normal (0)
• Slightly High (0.5)
• Very High (1)

*The reading speed and pitch adjustment features are currently being fine-tuned. The adjustment range and settings may change in the future.

Ondoku's New AI Voices Support Multiple Languages! Multilingual Text-to-Speech Available

Ondoku's new AI voices can read aloud in languages other than English as-is!

All voices support multiple languages including English and other foreign languages!

For example, here's what it sounds like when reading in French, Spanish, Korean, and Chinese.

All samples are read using the "Ellis" voice.

French
Instruction: "Lisez à haute voix joyeusement et avec énergie"

Bonjour, je suis Ondoku. Ma voix est devenue plus naturelle et plus humaine !

Ciao, sono Ondoku. La mia voce è diventata più naturale e più umana!

Important Notes for Multilingual Text-to-Speech with Next-Generation AI Voices

When using the new AI voices for multilingual text-to-speech in foreign languages, you need to specify the reading style in the language you want to use for reading.

In these samples, we have given the reading style instructions in each respective language.

If you give instructions in English like "Please read cheerfully and energetically" when reading other languages, it may result in unnatural pronunciation.

Support for Reading with Multiple Languages!

Unlike Ondoku's previous multilingual voices which required SSML tags, the new AI voices also support complex multilingual text-to-speech using multiple languages!

For example, this sample text can be read with proper pronunciation for each language—such as French or Spanish—by specifying the languages in the reading style field.

The voice used is "Ellis."

"Thank you" is Merci in French, Gracias in Spanish, and Danke in German.

*For instructions like this, you can write the reading style in English.
