What is monotone reading software (monotone reading apps) for PC?
Monotone voices are well-known from "Yukkuri commentary" on video sites.
Monotone voices can be read using PC software (apps).
What is a Monotone Voice?
Monotone voices are famous for their unique atmosphere.
Because they are used in "Yukkuri commentary" on video sites like YouTube and Niconico Douga, they are sometimes called "Yukkuri's voice" or "Yukkuri voice."
The speech synthesis engine used for monotone voices is AquesTalk.
By using text-to-speech software or apps equipped with AquesTalk, you can read text with a monotone voice.
Advantages of Monotone Voices (AquesTalk)
The biggest advantage of text-to-speech software and apps using monotone voices (AquesTalk) is that they operate very lightly.
AquesTalk was introduced in 2006.
Partly because it was originally developed for embedding in low-performance devices, it can read text smoothly even on low-spec PCs.
Since the software (app) places little burden on the PC, it is also widely used for reading game commentary.
Disadvantages of Monotone Voices (AquesTalk)
The disadvantage of text-to-speech software and apps using monotone voices (AquesTalk) is that they are not realistic.
If you are looking for realism, we recommend using a service that uses AI, like Ondoku.
Also, please note that free commercial use may not be possible depending on the version of AquesTalk.
3 Recommended PC Software/Apps for Monotone Voices + α

Among the integration features, the most commonly used is the comment-to-speech feature for video streaming.

In addition, features like reading Twitter (now X) posts and clipboard reading are also included.
Free Commercial Use Possible
Because Bouyomi-chan uses an older version of AquesTalk, it can be used commercially for free.

Workflow for Reading Text with Monotone Reading Software (Apps)
So, how do you use monotone reading software (apps)?
Using "Bouyomi-chan" as an example, we will explain the workflow for reading text in a monotone voice on a Windows PC.
1. Download Bouyomi-chan
First, download "Bouyomi-chan" to your PC from this page.
Clicking the download button will open the download page (Microsoft OneDrive).
Click the file name to download the ZIP file.
2. Extract the ZIP file
Extract the downloaded ZIP file.
Open the extracted folder.
(You can move the folder to any location you like.)
3. Launch Bouyomi-chan
"Bouyomi-chan" is software (app) that requires no installation.
You can launch it directly from the files within the extracted folder.
Double-click BouyomiChan.exe to launch "Bouyomi-chan."
*To launch "Bouyomi-chan," Microsoft .NET Framework 2.0 or higher must be installed.
Upon the first launch, you will be asked whether to enable plugins for:
- 2ch browser reading
- Clipboard monitoring
- Twitter reading
Enable plugins if necessary.
4. Enter the content to be read
Enter the content you want to read into the text box.
5. Read the text
When you press the "Speech Synthesis" button at the top left, the content entered in the text box will be read aloud.
(It is also possible to read text using the F5 key.)
6. Save the read content
By pressing "Save to File" next to "Speech Synthesis," you can save the content entered in the text box to your PC as a WAV file.
(It is also possible to save using the F6 key.)
Once you specify the save location, the speech processing will start automatically.
In this way, you can save the audio read by "Bouyomi-chan" to your PC as a WAV file.
This completes the workflow for reading audio using the text-to-speech software (app) "Bouyomi-chan."
Dialogue-style reading requires editing
When reading audio in a monotone voice, editing takes effort.
For example, in videos like "Yukkuri commentary," text is sometimes read as if multiple voices are having a conversation; in that case, the task of arranging and editing audio files in order becomes necessary.
For easy & realistic reading, Ondoku is also recommended
While using "Bouyomi-chan" allows you to read in a monotone voice for free, it requires some knowledge of Windows PCs to use.
Also, the audio read by software (apps) using AquesTalk like "Bouyomi-chan" is not very realistic.
If you want to read text with realistic audio that sounds just like a human is reading it, a text-to-speech service using the latest AI is recommended.
Workflow for Reading Text with Ondoku
By using the latest AI-powered text-to-speech service Ondoku, you can read text for free more easily than with software (apps) using monotone voices.
We will briefly explain the workflow for reading text using Ondoku.
1. Open the Ondoku page
Open the Ondoku top page from here.
2. Enter the text
Enter the text you want to read.
3. Choose a voice
Choose the voice you want to use for reading.
*Since Ondoku allows free reading, you can actually read short texts to check the voice tone.
4. Read aloud
When you press the "Read" button, the content of the text will be read aloud.
The read audio can be downloaded via the "Download" button.
This completes the workflow for reading text with Ondoku.
Dialogue-style reading is also easily possible
To read dialogue-style text with monotone software, it was necessary to export each voice type separately and then edit them.
With Ondoku, it is possible to read and save dialogue-style audio using multiple voice tones at the same time!
Tedious editing work is unnecessary, so you can create dialogue-style videos more easily.
Since you can read text for free with more ease and functionality than using monotone voice software (apps) on a PC, why not experience Ondoku for yourself?
