How to create YouTube video narration using the latest AI? Basic knowledge explained

I want to upload a video to YouTube, but adding my own narration is a pain...

For those of you who are in this situation, we will first provide a simple explanation of the basics of video narration using the latest AI.

How to use AI for narration in YouTube video production?

AI technology is advancing rapidly.

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

Many video creators on YouTube are already using AI narration.

Previous text-to-speech software and services could only read in an unnatural, robotic voice.

But today's voice synthesis AI is different.

The AI model, which has learned from large amounts of audio and text data, understands the content of the text and reads it with realistic intonation and timing, just as if a real narrator were reading it .

Now that it is possible to read in a natural voice, voice-synthesized narration is now widely used outside of specific genres such as slow commentary.

AI text-to-speech service makes it easy to create YouTube videos

Until now, narration production required hiring a professional narrator or recording it yourself.

With AI technology, it is possible to create natural-sounding narration that sounds as if a human is reading it, simply by inputting the script text .

By utilizing the latest AI, you can create the YouTube videos you want much more easily than ever before, without having to pay for a narrator or go through the trouble of recording them yourself.

The advent of AI text-to-speech services has significantly lowered the barrier to video production, making it easy for anyone to add narration to YouTube videos.

What are the benefits of using an AI reading service to narrate YouTube videos?

• I want to make a video, but I'm reluctant to use my own voice.
• Hiring a professional is expensive and difficult...

In such cases, we recommend creating narration using an AI reading service.

We will explain the benefits of using AI to create narration.

You can create videos without showing your face or speaking!

The biggest advantage of producing videos on your own is that you can add narration to the video without speaking your own voice .

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

In such cases, we recommend using the latest AI to provide narration.

By using the AI reading service, you can easily create narration by simply entering text .

There is a wide variety of voices available, including female, male, and even child voices, so you can add narration in the voice of your choice .

Narration can be produced at a lower cost than hiring a narrator

AI narration is also recommended for companies and public institutions when creating videos for YouTube for business purposes.

The biggest advantage of using AI narration for business purposes is that it allows you to provide high-quality narration at a low cost .

For videos on your company's official channel, such as product promotional videos, you want to include professional, high-quality narration .

However, if you hire a professional narrator, it will cost several tens of thousands of yen at the very least.

It's a huge burden to have to spend tens of thousands of yen every time you upload a new video to your YouTube channel.

In such cases, we recommend using an AI reading service!

The AI reading service is available for just 1,000 to 3,000 yen per month.

There are also free services available , so you can upload official videos to YouTube without worrying about costs.

Many paid text-to-speech software programs have licenses that make them difficult to use in companies, but the AI text-to-speech service "Ondoku" is OK for commercial use , making it ideal for business use.

Video narration available 24 hours a day

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

If you were to hire a narrator, you would need to check the availability of a recording studio and coordinate schedules, but with AI technology, you can create a recording immediately whenever you think of it .

I make videos on my own, but I can't speak loudly at night because I'm renting.

If you are such a person, we recommend creating narration using an AI reading service.

From individual YouTubers to those creating official videos for companies, using an AI reading service can make creating video narration very convenient.

• Product Introduction

Try writing a script based on the content of the video, such as:

But often the script isn't written well.

In such cases, we recommend using a generative AI service!

First, write freely and as you think, without worrying about style or tone.

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

First, try writing in the tone you normally use when speaking.

We also recommend using the voice input feature on your smartphone or PC to actually speak and input .

Next, we load the script file into a generative AI service such as ChatGPT, Claude, or Google Gemini ,

This is a draft script for a YouTube video. Please use this draft to create a script for a video about ____ (e.g., a company product introduction). Please make sure the tone of the script matches the content.

This is how I instruct it.

It will then rewrite the text in a tone (style) that perfectly matches the content of the video.

Finally, read the file created by the AI generative service and check for any errors in the content.

Tips for using AI-generated narration in YouTube videos to make them more engaging

Finally, we will introduce some tips to make using AI-generated video narration audio even more appealing.

By simply mastering a few simple video editing tricks, you can create compelling videos like those made by popular YouTubers.

Boldly cut out unnecessary parts of the narration audio

For those who are making videos on their own , we recommend cutting out unnecessary silent parts of the narration .

When you watch videos of major YouTubers , you often see them speaking at a rapid, rapid pace.

Actually, this isn't how I've been talking about it from the beginning.

Unnecessary parts of the audio have been cut out and edited to create an audio with a faster tempo than the actual audio.

AI voice can synthesize realistic and fast-paced voices, but if the gaps between sentences feel too long, we recommend cutting them out and editing them.

Unlike the audio of an actual person speaking, AI audio does not contain unnecessary parts such as "um" or "ah," making it very easy to edit.

With just a little editing, you can create narration like a popular YouTuber.

On the other hand, there is no need to cut or edit official videos for companies or corporations.

By leaving spaces between sentences, you can create a calm image.

Pay attention to the volume balance between the narration and background music

Background music is an essential part of YouTube videos.

When adding background music, be careful to balance the volume with the video narration.

The background music audio files are produced at a volume that can be listened to as music on its own.

When adding background music to a video, you need to lower the volume all at once .

For example, if you are editing a video in Adobe Premiere, lowering the background music volume to around -30db will achieve an appropriate volume.

Why not try creating a free YouTube video narration using an AI reading service?

Advances in AI technology have made it possible for anyone to easily create narration for YouTube videos, free of charge .

AI reading services are also recommended for those who are reluctant to show their face or speak out loud.

Anyone, from individuals who create videos to those who create videos for companies or organizations, can easily create high-quality narration.
