Reasons to Add Narration to Corporate Introduction Videos

When creating a corporate introduction video, adding narration can enhance its persuasive power and more strongly appeal to the company's charms.
While visual images (sight) can convey information in a detailed and broad manner, they are less effective than audio at leaving a strong impression at critical moments.
In contrast, audio (hearing) allows for expressions that appeal more to emotions, such as speaking slowly with pauses at important points or changing the tone of voice depending on the scene in the video.
By adding narration, you can create a video that does not just convey information but also leaves a strong impression.
Enable a Wider Range of Appeal

Furthermore, by adding narration, it is possible to appeal to a wider range of consumers and businesses.
For example, by adding foreign language narration to a video, you can appeal to overseas audiences.
Since you only need to replace the narration audio with a foreign language, it is much easier than producing a video from scratch.
Also, conveying information via audio as well as visuals improves accessibility for those with visual impairments.
To appeal to your company more broadly and improve accessibility, adding narration to your videos is recommended.
Narration Can Be Easily Produced with AI

Previously, to add narration to a corporate introduction video, it was necessary to hire professional narrators or voice actors, which required high costs.
It was certainly possible to record your own voice, but in that case, the audio often became very difficult to hear.
But it's different now!
With the advancement of AI, it has become possible to automatically create easy-to-hear audio files based on input text!
The latest AI text-to-speech services can easily generate professional-grade, easy-to-hear audio for anyone.
Additionally, AI text-to-speech services can read in foreign languages, including English.
By reading a foreign language script created with an AI translation service, you can easily produce corporate introduction videos for international audiences.
AI Allows for Free Narration Production
What's more, AI text-to-speech services are available for free!
If you are making narration for a corporate introduction video, AI text-to-speech services are recommended.

How to Choose a Recommended AI Text-to-Speech Service
There are many types of text-to-speech services using AI and software that you install on your PC.
Here we briefly explain the points to consider when choosing a method to create narration for corporate introduction videos.
1. Choose a Service that Allows Commercial Use

Narration for corporate introduction videos falls under commercial use.
Caution is required as some text-to-speech services or software prohibit commercial use.
Additionally, some services or software incur high additional fees for commercial use.
When creating narration for corporate introduction videos, it is best to choose a service that allows commercial use for free.

2. Services Without Preset Characters Are Recommended

Some text-to-speech services and software, such as VOICEROID, have character illustrations set for them.
While attractive for hobbyist videos or creative works, characters are unsuitable for corporate introduction video narration.
The reason is that the character's impression remains stronger than the company's impression.
Also, services or software with character illustrations often have stricter terms of use.
When creating narration for corporate introduction videos, we recommend choosing one without characters.
3. Choose a Service that Can Read in Foreign Languages

To appeal more broadly, we recommend choosing a service that can read in foreign languages.
Depending on the service or software, it may only be able to read one language, such as just Japanese or just English.
Conversely, there are services capable of reading many languages, such as "Ondoku", which can read 48 languages.
If you want to promote your company globally, we recommend using a text-to-speech service that supports many languages.

The Flow of Creating Corporate Introduction Video Narration with "Ondoku"

We will explain the flow of creating narration for a corporate introduction video for free using "Ondoku"!
1. Create a Script

First, create a script for the corporate introduction video.
The tools to create a script can be:
- Word processing software such as Word
- Text editors such as Notepad
- Cloud services such as Google Docs
Anything is fine.
Script data can be utilized for other purposes like YouTube subtitles, so be careful to take backups frequently.
One thing to remember when deciding the length of the script is the standard character count when speaking in Japanese.
The standard narration speed is about 300 characters per minute.
- 5-minute video: 1,500 characters
- 10-minute video: 3,000 characters
This is a guide.
Divide by Sentence Using "。"
When writing a script for reading with "Ondoku", the key is to always input a period "。" at the end of a sentence.
"Ondoku" has a function to download reading results in segments, and in that case, "。" becomes the splitting point for files.
Since it is convenient during video editing, we recommend dividing sentences with "。".

Once the reading is complete, an audio player will be displayed.
Play the reading result to check if there are any issues.

If there are no problems, press the "Download" button to save the audio file.

What to do when corrections are needed?
If you find a part that needs correction, you don't have to re-read the whole thing; you can generate separate audio for just that part later.
In that case, you cut and join the audio when editing the video.
Split Download of Audio is Also Possible
"Ondoku" allows for split downloading of audio!
To download audio in segments, first open "History" from the menu.
