Points for Utilizing Yukkuri Voice and Monotone Voice Software

First, create a script for the video.

The key is to divide it into short sentences so it is easy to read aloud.

Next, enter the script into your chosen Yukkuri voice or monotone voice software and generate the audio.

Choose a tool that suits your environment, such as "Bouyomi-chan" for PC software or "Yukkuri Bouyomi Talk" for smartphone apps.

Software that generates Yukkuri voice is lightweight, so if it doesn't go well, try adjusting the text and regenerating it.

Finally, add BGM and effects to increase the quality and export the video.

By following this basic workflow, even beginners can easily create Yukkuri voice videos.

As you gain experience, gradually hone your techniques.

Tips for Audio Settings for Commentary and Narration

Here are some tips for audio settings ideal for game commentary and narration.

In game commentary, the balance with game sound is important, so settings that prioritize clarity are recommended.

In PC software like "Bouyomi-chan," set the speed a little faster and make the volume slightly louder than the game sound to make it easier to hear.

In commentary videos and narration, ease of understanding the content is important, so settings that read aloud slowly and clearly at a standard speed are appropriate.

When using AI services other than Yukkuri voice, such as Ondoku, choosing a voice with natural intonation can achieve more professional and reliable narration.

For long commentaries, consider the viewer's ear fatigue and choose a slightly lower pitch and calm voice quality.

Also, in both PC software and smartphone apps, try incorporating pauses at important points to make the content easier to convey.

By providing appropriate intervals between sentence breaks, viewers can listen while organizing the information.

Furthermore, if you adjust the reading settings for technical terms or game-specific words in advance, the narration will sound more natural.

By following these tips, you can create commentary and narration videos that are comfortable for viewers to listen to.
