Project and File Structure
When you start using NaturalReader AI Voice Generator, everything you create is organized into Projects and Files. Think of Projects as folders, and Files as the documents inside them.
There are two types of Projects:
• Your Projects – Private Projects that only you can access.
• Team Projects – If you are on a Team Plan, you can create shared Projects that all team members can access. While everyone can view the content, only one person can edit a File at a time.
Files contain the text you want to convert into audio, organized into blocks. Each File can contain up to 100 blocks on paid plans or 20 blocks for free users. Character limits per block vary depending on the voice selected from .
Each block can be downloaded as an individual audio file, or you can combine all blocks into a single MP3 file.
Note: NaturalReader AI Voice Generator (commercial version) does not convert directly from uploaded documents. You can create Files by typing, pasting, or generating text with AI.
Getting Started
To help you get started testing voices and features, every account starts with a default private Project called "My First Project". This Project includes a default File called "Welcome to NaturalReader Commercial".
When you first open the AI Voice Generator, the Library displays this default Project and File. On subsequent visits, the Editor opens the most recently used File.
Since a Project is already set up for you, you can start creating new Files right away, rename the default Project, or create new Projects to organize your work.
Managing Projects
Remember, "Files" are the content you're creating while working with text to convert and download into audio. "Projects" are the folders you keep your Files in. Both Projects and Files can be managed from the Library.
Select Library from the sidebar menu. This lists all the Files in your current Project.
Click the current Project name above the File list to view all your Projects.
This opens the Select a Project window. From here, you can open, create, rename, or delete Projects. Choose Your Projects or Team Projects to view your private or shared Projects, respectively.
Select the Sort icon to organize your Projects by name (ascending or descending) or by last edited.
Select a Project from the list, then choose Select Project to open it.
Creating Projects
In the Select a Project window, choose Your Projects to create a private Project or Team Projects to create a shared Project.
Select Create New Project.
Enter a name, then select Create to finish or X to cancel.
Quick Method: You can also click the Options (three dots) icon at the top of the Library panel and select New Project. Enter a name, then select Create.
Keep in mind that this method creates a Project of the same type as the one currently open. If you're viewing a private Project, the new Project will also be private. If you're viewing a Team Project, the new Project will also be shared with your team.
Renaming Projects
In the Select a Project window, select the Project you wish to edit from either Your Projects or Team Projects.
Choose the Edit (pen) icon.
Enter a new name. Project names must be unique, so you cannot have multiple Projects using the same name.
Select Save to finish or X to cancel.
Deleting Projects
In the Select a Project window, select the Project you wish to delete from either Your Projects or Team Projects.
Choose the Delete (trash) icon.
If you're sure you want to permanently delete the Project, select Delete Project to confirm or X to cancel.
Keep in mind: When creating new Files, they are generally saved to the Project you currently have open or the one you last accessed.
Creating New Files
As we've already covered, Projects are the folders you organize your Files into. Files are like documents that contain the text you want to convert into audio. Within each File, you can edit your text, select voices, and adjust speech settings before generating and downloading your audio.
The new file you're creating will be saved to the Project you currently have open or the one you last accessed. To save it to a different Project, open Library, click the current Project name, and select the Project you want to add to before creating your File.
To create a new File using your own text:
Select Text to Speech from the sidebar menu to open the File creation page.
Make sure Text is selected, then click Untitled File to enter a name for your File.
Type or paste your content into the text field.
Choose whether to enable or disable Auto Split Paragraphs to control how your text is divided into blocks. This determines whether blocks follow your original paragraph breaks or are automatically grouped by character count. See below for details.
In the Voice Settings panel, select your voice(s) and configure the initial speech settings for your File. Your settings here can be changed later. See below for more information about voice settings and templates.
Once you're ready, click Create to create your File.
Auto Split Paragraphs
This option controls how your text is divided into blocks when creating a File. It is enabled by default.
Important: When Auto Split Paragraphs is enabled, paragraphs are not automatically divided to fit the selected voice's character limit. A paragraph may be accepted when creating the File but still exceed the voice's limit. If this happens, you'll need to split the oversized block manually in the Editor before generating audio.
When enabled:
Each paragraph separated by a line break becomes its own block.
Empty lines are ignored, and short paragraphs are not combined.
Paragraphs containing 5000 or more characters are not accepted. Longer paragraphs must be divided before creating the File.
If your text produces more than the maximum number of blocks allowed, the File cannot be created.
When disabled:
Text is automatically grouped into blocks of approximately 2000 characters.
Longer paragraphs are divided at sentence or line boundaries as needed.
Each File supports up to 100 blocks on paid plans or 20 blocks for free users.
Character limits per block depend on the selected voice provider:
Azure: 4000 characters
Google, ElevenLabs, Gemini, Cloned Voices: 3000
OpenAI: 2000
Voice Settings
The Voice Settings panel lets you configure the initial voices and playback settings for your File.
Speakers
Choose at least one voice for your File. You can preview, change, or remove voices from the Speakers list.
For a single voice, remove any additional speakers so only one remains.
To alternate between voices automatically, add or configure up to three speakers.
If you need more than three alternating speakers, you can assign additional voices manually in the Editor after creating your File.
Your selected speakers will be applied to the text when the File is created. You can change voices and speaker assignments later in the Editor.
Speed
Adjust the reading speed using the slider. This initial setting applies to all blocks, but you can customize the speed of individual blocks later.
Pause Between Paragraphs
Adjust the pause duration between blocks. This setting initially applies throughout the File, but individual pauses can be customized later in the Editor.
Templates
You can save your current speaker and playback settings for future use.
Click Save as new to create a template.
Select Save as default if you want to use these settings as your default template.
Click Load Templates to choose a previously saved template or browse available presets.
These are quick setup options. You can continue adjusting voices, speed, and pauses for individual blocks after creating your File.
Script Generator
You can also use AI to help create content for your File. The same Voice Settings and File creation options apply.
Select Text to Speech from the sidebar menu and choose the AI tab on the File creation page.
Click Untitled File to enter a name for your File.
In Describe Your Project, enter a prompt describing the content you want AI to generate. You can also click Presets to choose a suggested prompt and edit it to suit your needs.
Click Go to generate your script.
Review the generated text and make any changes you want. You can also use the AI editing field to request further revisions.
Once you're satisfied with the script and your settings, click Create to create your File.
Creating Files from the Library
When you open Library, you may also see the File creation page alongside your current Project. From here, you can create a new File for the Project or select an existing File to open and edit it.
Managing Files
Once a File has been created, you can manage it in the Library. This includes navigating between other Files in the Project, sorting, renaming, duplicating, deleting, exporting, moving Files to another Project, or restoring a previous version.
Navigating Files
We've already covered how to navigate between your Projects. When you select Library from the sidebar menu, it will list all the Files in your opened Project.
Simply click on the File you wish to work on and you can edit its text and settings directly from the Editor panel.
To change how your Files are listed, select the Options (3 dots) icon at the top of the File list panel. You can sort it by name or by last edited, and both either ascending or descending.
Renaming, Duplicating, and Deleting Files
Select Library from the sidebar menu.
If needed, click your Project name to switch to a different Project and edit its Files.
Mouse over the File list and click on the More (3 dots) icon
Choose one of the following actions:
Rename: Change the File name.
Duplicate: Create a copy of the File.
Delete: Permanently remove the File. Do not select this unless you are certain, as it will not ask for confirmation.
You can also delete multiple Files at once.
In the Library's File list panel, select the Options icon (horizontal 3 dots) at the top of that panel
Choose Select
Click on the Files you want deleted, or choose Select all to choose all Files
Select Delete
If you're sure you want to delete the Files, choose Yes to finish or Cancel to exit
Transferring Files Between Projects
You may want to reorganize your Files by moving them to another Project. If you want a File to exist in more than one Project, duplicate it first before transferring. Keep in mind that duplicated Files are independent. If you edit one copy, the changes will not apply to the other.
Select Library from the sidebar menu.
If needed, click your Project name to switch to a different Project and edit its Files.
Mouse over the File you wish to transfer and click on the More (3 dots) icon.
Select Move to another project.
Use the drop-down to select a Project to move it to.
Choose Save to finish the transfer, or Cancel to exit
Restoring File History
Your text and File content are saved automatically every 30 seconds. If you make a mistake or something doesn’t sync properly, you can restore a previous version of the File.
Select Library from the sidebar menu
Mouse over the File and click the More (3 dots) icon
Select Restore History Files
If available, previous versions will be listed under Other File History with timestamps
Mouse over the version you want to restore and click Restore
If a previous version is available, it will open as a new File titled “Copy of [File Name]” so your current version remains unchanged.
Exporting and Importing Project Files
Aside from the shared Team Projects for users on a group subscription, there’s no way to transfer Projects between accounts except for using the export/import function.
You can manually export Files that can be imported by any user to their own account to continue to be worked on.
The AI Voice Generator exports your Files in a unique .nkl file type that can be used in NaturalReader only.
Exporting Single Files
Select Library from the sidebar menu.
Mouse over the File and click the More icon (vertical 3 dots) and choose Save to local file (*.nkl).
Choose a destination and select Save to finish.
Exporting Multiple Files
You can export selected File within a single Project at once.
Select Library from the sidebar menu.
From the Library’s File list panel, click on Options (3 horizontal dots) at the top and choose Select.
Click on the checkboxes to mark which Files to export.
Select the Download icon (*.nkl).
Choose a destination and select Save to finish.
Your Project’s Files will be saved in a folder.
Exporting Full Projects
You can export all Files from a single Project in one step, but Files from different Projects must be exported separately.
Select Library from the sidebar menu.
From the Library’s File list panel, click on Options (3 horizontal dots) at the top and choose Download Project.
Choose a destination and select Save to finish.
Your Project’s Files will be saved in a folder.
Importing Files
Files can be imported one at a time only. You cannot batch import Files. Keep in mind this function is for importing previously exported AI Voice Generator Project Files and is not about uploading text document formats, which the app does not support.
Select Text to Speech from the sidebar menu.
Choose Import
Navigate to and select the .nkl File to open.
The File will be imported into the current Project and can be worked on again.
