How to Create YouTube Video Narration with the Latest AI? Basic Knowledge Explained

I want to upload videos to YouTube, but it's hard to do the narration myself...

For those of you, we will first briefly explain the basic knowledge of video narration using the latest AI.

How to Utilize AI for Narration in YouTube Video Production?

AI technology is advancing rapidly.

In the field of video production as well, speech synthesis AI that generates natural speech from text is attracting attention.

Many video creators are already using AI narration on YouTube.

Previous reading software and reading services could only read aloud with a robotic voice that felt unnatural.

But today's speech synthesis AI is different.

AI models that have learned from massive amounts of voice and text data understand the content of the text and read it aloud with realistic intonation and pauses, as if a real narrator were reading it.

Since it can now read aloud with a voice that feels natural, synthesized narration has become widely used in genres beyond specific ones like commentary videos.

You Can Easily Create YouTube Videos with AI Reading Services

Previously, producing narration required hiring a professional narrator or recording it yourself.

With AI technology, it is possible to create natural narration audio as if a human were reading it just by entering the script text.

Since it eliminates the cost of hiring a narrator and the effort of recording yourself, utilizing the latest AI allows you to create YouTube videos exactly as you imagine, much more easily than before.

The appearance of AI reading services has significantly lowered the bar for video production, making it easy for anyone to add narration to YouTube videos.

What Are the Benefits of Using AI Reading Services for YouTube Video Narration?

• I want to make videos, but I'm hesitant about using my own voice
• It's difficult to hire a professional due to costs...

In such cases, creating narration with an AI reading service is recommended.

Let's explain the benefits of using AI to create narration.

Video Production Possible Without Showing Face or Voice!

The biggest benefit when producing videos individually is that you can add video narration without using your own voice.

When uploading videos to sites like YouTube, there are many cases where you don't want your private information, such as age or gender, to be known.

In such cases, adding narration with the latest AI is recommended.

By using an AI reading service, you can easily produce narration just by entering text.

Since there is a wide variety of voice types, including female, male, and children's voices, you can also add narration in your ideal voice.

Possible to Produce Narration at a Lower Cost Than Hiring a Narrator

AI narration is also recommended when creating videos for YouTube for business purposes, such as at companies or public institutions.

The biggest benefit of using AI narration for business is that you can add high-quality narration at a lower cost.

For videos on official corporate channels, such as product promotion videos, you want to include professional, high-quality narration.

However, hiring a professional narrator costs tens of thousands of yen at a minimum.

It is a significant burden to pay tens of thousands of yen every time you upload a new video to your YouTube channel.

In such cases, using an AI reading service is recommended!

AI reading services can be used for as little as 1,000 to 3,000 yen per month.

There are also services that can be used for free, so you can upload official videos to YouTube without worrying about costs.

Many paid reading software programs have licenses that make it difficult for companies to use, but the AI reading service Ondoku is OK for commercial use, making it ideal for business use.

Narration Production Possible 24 Hours a Day

Another benefit of AI reading services is that you can produce high-quality narration that rivals professional narrators at any time.

When hiring a narrator, you need to coordinate schedules and check the availability of recording studios, but with AI technology, you can produce it as soon as you think of it.

I produce videos individually, but since I live in a rental, I can't use my voice late at night

For you as well, creating narration with an AI reading service is recommended.

From individual YouTubers to those making official videos for companies, anyone can create video narration very conveniently by using an AI reading service.

No Audio Editing Required! Significantly Shortens Video Editing Time

Anyone who has actually produced a video will definitely agree with this benefit.

If you create narration with an AI reading service, no audio editing is required, and you can use it as is!

When you record narration yourself, editing is required to cut out things like:

• Mistakes in speaking
• Silent periods
• Parts with poor tempo

But in fact, this task is very difficult.

It is common to take over an hour to produce 5 minutes of audio.

In contrast, with an AI reading service, you can create audio in just a few seconds that can be played as is without editing.

Since you can drastically reduce the effort of video editing, you can post videos to YouTube more casually.

I want to know how to create a video with narration using AI!

Next, we will explain how to create YouTube video narration for free using the AI reading service Ondoku!

We will also explain tips for video editing, so please try creating a video by referring to them.

1. Create a Script for the YouTube Video

First, create a script for the YouTube video.

• Commentary video
• Game commentary
• News video
• Company introduction
• Product introduction

Try writing a script according to the content of the video.

However, there are many cases where you can't write a script well.

In such cases, utilizing generative AI services is recommended!

First, write the text freely as you think, without worrying about the writing style or tone.

At this point, you don't need to worry about the linguistic expressions.

First, try writing it just as you would normally speak.

It is also recommended to actually speak and input using the voice input on your smartphone or PC.

Next, load the script file into a generative AI service such as ChatGPT, Claude, or Google Gemini and give instructions like this:

This is a draft for a YouTube video script. Based on this draft, please create a script for a video about [Example: corporate product introduction]. Please use a tone that matches the content.

Then, it will rewrite it into a tone (writing style) that is perfect for the video content.

Finally, just read the file created by the generative AI service and check if there are any errors in the content.

With this, you have created a script for YouTube video narration.

Generative AI services like ChatGPT, Claude, and Google Gemini can be used for free, so it is recommended to actively use them when creating YouTube videos.

2. [Free] Generate AI Narration Audio with Ondoku

Since Ondoku's audio files are in MP3 format, they can be loaded into either without any problems.

4. Upload the Finished Video to Your YouTube Channel

A point when uploading a video is to input a clear title and description.

Based on this script, please think of a title and description content for a YouTube video

By setting subtitles, you can convey the content to more viewers.

You can also have subtitles automatically translated for overseas viewers to watch, so you can further increase views and have people all over the world subscribe to your channel.

Tips for Using AI-Generated Narration More Attractively in YouTube Videos

Finally, we will introduce tips for using narration audio created with AI even more attractively.

Just by grasping a few tips for video editing, you can create attractive videos like a popular YouTuber.

Boldly Cut Unnecessary Parts of the Narration Audio

Recommended for those creating videos individually is cutting unnecessary parts of the narration.

When watching videos by major YouTubers, there are many cases where they are speaking at a fast and good tempo as if one thing follows another.

This is actually not how they speak from the beginning.

They edit the audio by cutting unnecessary parts to make it a better-paced audio than it actually is.

If you actually try reading the script and feel that the linguistic expressions are too redundant, we recommend boldly editing and cutting them.

The impression of text changes significantly between seeing it as characters in a script and actually hearing it as audio.

Parts that you feel are "unnecessary" when turned into audio will result in a much easier-to-watch video if you just cut them out.

Conversely, for official videos of companies or corporations, it may be just right to have a little more information.

By daring not to cut off information, you can enhance the reliability required for official information.

Pay Attention to the Volume Balance Between Narration Audio and BGM

BGM is essential for YouTube videos.

When adding BGM, pay attention to the volume balance with the video narration.

BGM audio files are produced at a volume intended for listening to them individually as music.

When inserting BGM into a video, you need to lower the volume drastically.

For example, when editing a video with Adobe Premiere, the volume will be appropriate if you lower the BGM volume to about "-30db."

Why Not Try Creating YouTube Video Narration for Free with an AI Reading Service?

With the advancement of AI technology, anyone can now easily create YouTube video narration for free.

AI reading services are also recommended for those who are hesitant to show their face or use their voice.

From those producing videos individually to those making videos in companies or organizations, anyone can easily create high-quality narration.
