Hello! This is Supertone Play 💙

Are you new to AI voice generation, or do you want a more detailed guide on how to create high-quality AI voices?

This article is a practical guide designed to help content creators make natural, expressive TTS voices using Supertone Play’s voice features.

If you’ve ever wondered…

‍

How do I choose the right voice for me?

Which model should I use?

Where do I adjust emotion/tone settings?

Why is my voice-cloning output low quality?

👆 If you have these questions, follow the steps below!

‍

🗣️ [Step 1] Choosing a Voice: Find the Perfect Voice for Your Content

‍

In the Supertone Play home screen, scroll down to the “Listen to a variety of voices with your own script!” section.

Here, you can browse newly added voices, recommended voices, and voice styles suited for various use cases.

‍

👉 Use the categorized tags to quickly find the tone that matches your production style.

Click on a voice to preview a sample, or click the pencil icon to enter your own script and hear it generated with that voice.

Click the + button to instantly add the voice to your project.

‍

🗣️ [Step 2] Start Creating: Projects

‍

To begin building your content, open the “Projects” tab from the left menu and click “Create New Project.”

When creating a project, you’ll choose a title and a voice model.

If you’re unsure which model suits your content, click “About Sona Models” above the selection area for detailed explanations.

High-quality models: Sona 1, Sona 2

Fast model: Supertonic

‍

After choosing a model, you’ll see the voice library.

You can filter voices by gender, age range, and use-case tags, which can be combined for more precise searching.

‍

Click a voice to see its speaking-style keywords, and preview each style by clicking the keywords.

This makes it easier to understand the atmosphere and choose the perfect voice for your project.

‍

🧪 [Step 3] How to Generate & Download TTS

‍

There are two ways to generate audio:

• Click the green “Generate” button in the bottom-right corner
• Turn on “Press Enter to Generate” toggle on the top center

Add lines using the “Add New Line” box and continue writing your script.

Once generated, click the “Download” button on the top-right of each line.

You can select all lines at once or choose specific ones.

‍

🎧 Audio Download Options

1. Save as Separate Files

Each line is downloaded as an individual file.

From the Creator plan and up, you can adjust spacing between words.

2. Save as a Single File

Multiple lines are merged into one file.

You can also adjust spacing between sentences or words.

Choose the format that best fits your workflow!

‍

🎛️ [Step 4] Creating Natural & Accurate AI Voices

‍

Supertone Play is more than a simple TTS generator—it captures emotion and context.

So the structure and clarity of your input text greatly affect the output.

‍

✂️ Use complete and clear sentences

• Missing punctuation or overly short/long sentences may be read incorrectly.
• Break long sentences into smaller ones.
• Use commas to help with natural pauses.
• Supertonic (beta) may struggle with very short sentences.

‍

🔁 Repeated or missing words?

Try restructuring or splitting the sentence.

‍

💡 Rewrite numbers for clarity

“10,000 won” → “ten thousand won”

Fully spelled-out numbers produce more natural speech.

‍

🧰 [Step 5] Use Advanced Features for 200% Efficiency

‍

1. Select & Control Speaking Styles

Most voices offer multiple emotional styles such as Angry, Sad, Happy, etc.

Styles with a + represent stronger intensity:

Example: Angry+ > Angry

‍

2. Voice Parameters

• Pitch: raise or lower voice tone
• Pitch Variation: expressiveness vs. monotone
• Speed: faster or slower speaking
• (The Supertonic model currently supports only speed.)

‍

Speeding to 2.0x reduces a 4-second line to 2 seconds—perfect for fast-paced short-form content!

‍

3. Use <laugh> and <clear> for natural expressions (Sona 2 only)

Insert:

• <clear> → throat clearing (e.g., “ahem”)
• <laugh> → laughter (e.g., “haha”)

Tips:

• Placing two tags doesn’t lengthen the effect.
• They may not work if inserted mid-word.
• English performance may vary.
• Only available in Sona 2.

‍

4. Voice Cloning Tips

If your cloned voice sounds unnatural:

• Record in a quiet environment
• Use an external microphone
• Enunciate clearly
• Avoid laptop built-in mics when possible

‍

🎙️ [Step 6] Record Your Own Voice for Custom Character Creation

‍

If you can’t find the perfect tone, simply record your own voice!

Click Generate with Audio, then choose to record or upload an audio file.

Tips for best results:

1. Ensure adequate microphone volume
2. Use clean, noise-free recordings
3. Prefer external microphones
4. Perform as if you’re acting the character you want to create

‍

📥 [Step 7] Import Scripts

‍

You can import .txt files directly into Supertone Play.

This is especially useful when preparing scripts externally before production.
