Narration is Recommended for Attractive Company Introduction Videos!
If you want to promote a company's appeal more effectively through video, we recommend utilizing narration.
By using the latest AI, anyone can easily add video narration for free.
Reasons to Add Narration to Company Introduction Videos
When creating a company introduction video, adding narration can increase its appeal and more strongly showcase the company's charms.
Images (visuals) can convey information in detail and breadth, but they are less effective than audio at leaving a strong impression during crucial moments.
In contrast, audio (auditory) 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 video scene.
By adding narration, you can create a video that leaves a strong impression, rather than just conveying information.
Enabling Broader Appeal
Additionally, adding narration makes it possible to appeal to a wider range of consumers and businesses.
For example, by adding narration in foreign languages to a video, you can appeal to overseas markets.
Since you only need to replace the narration audio with a foreign language, it is much easier than producing a video from scratch.
Furthermore, by conveying information through audio as well as visuals, you can improve accessibility for the visually impaired.
To promote the company more broadly and improve accessibility, we recommend adding narration to your videos.
Narration Can Be Easily Produced with AI
Previously, to add narration to a company 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 ended up being very difficult to hear.
But that'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 allow anyone to easily generate professional-quality, easy-to-hear audio.
Additionally, AI text-to-speech services can read in foreign languages, including English.
By reading aloud foreign language scripts created with AI translation services, you can easily produce company introduction videos for international audiences.
AI Enables Free Narration Production
Moreover, AI text-to-speech services are available for free!
If you are making narration for a company introduction video, AI text-to-speech services are recommended.
Why not showcase your company's appeal to more customers with high-quality narration?
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.
We will briefly explain the key points to consider when choosing a method for creating narration for company introduction videos.
1. Choose a service that allows commercial use
Narration for company introduction videos falls under commercial use.
Care must be taken as some text-to-speech services or software may prohibit commercial use.
Additionally, some services or software may charge high additional fees for commercial use.
When creating narration for a company introduction video, it is best to choose a service that allows commercial use for free.

However, please note that Ondoku has established prohibited acts. This time, we will cover what you can and cannot do with Ondoku...
2. Services without set characters are recommended
Some text-to-speech services and software, such as VOICEROID, have character illustrations set.
While attractive for hobbyist videos and creative works, characters are unsuitable for company introduction video narration.
The reason is that the character's impression remains stronger than the company's impression.
Additionally, text-to-speech services or software with character illustrations often have stricter terms of use.
When creating narration for a company introduction video, 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 aloud 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.
On the other hand, there are services like Ondoku that can read aloud in many languages, such as over 80 languages and dialects.
If you want to promote your company worldwide, we recommend using a text-to-speech service that supports many languages.

The Process of Creating Narration for a Company Introduction Video with Ondoku
We will explain the process of creating narration for a company introduction video for free using Ondoku!
1. Create a Script
First, create a script for the company introduction video.
The tool for creating the script can be anything:
- Word processing software like Word
- Text editors like Notepad
- Cloud services like Google Documents
Since script data can be used for other purposes like YouTube subtitles, be careful to take frequent backups.
When determining the script length, a point to remember is the standard number of characters when speaking Japanese.
The standard narration speed is 300 characters per minute.
- 5-minute video: 1,500 characters
- 10-minute video: 3,000 characters
is a rough guide.
Separate sentences with a "。"
When writing a script for reading aloud with Ondoku, the key point is to always enter a "。" at the end of a sentence.
Ondoku has a function to split and download the reading results, and at that time, "。" becomes the file's split point.
Separating sentences with a "。" is recommended because it is convenient during video editing.
*The split download function will be explained in the latter half!
2. Read Aloud with Ondoku
Once the script is finished, read it aloud using Ondoku.
To read aloud, first open the Ondoku homepage from here.
Paste the script text into the text box on the homepage.
Select the voice.
*Voice samples are introduced in this article.
Now the preparation is complete.
Press the "Read Aloud" button to start the reading.
For a script for one video, the reading will be completed in just a few seconds!
3. Check the Audio and Download
When the reading is finished, an audio player will be displayed.
Play back the reading results and check if there are any issues.
If there are no problems, press the "Download" button to save the audio file.
What if a correction is needed?
If you find a part that needs correction, you don't have to re-read the whole thing; it's okay to generate the audio for just that part separately later.
In that case, you cut and join the audio when editing the video.
Audio Split Download is Also Possible
Ondoku allows for split downloads of audio!
To split and download audio, first open "History" from the menu.
Opening the history page will display a list of reading results.
Select "Split" on the right side.
The split download screen will open.
Selecting "Split and Download" will start the file splitting.
When the splitting is finished, the download will start automatically.
The files are compressed in ZIP format.
