Hello, in this article, we will explain troubleshooting for downloading and playing Ondoku files.
Most people who use Ondoku have likely used the download function at least once.
Converting text to speech and downloading it as an mp3. This feature is very convenient, isn't it?
The intended use of downloaded files varies by user.
It is no exaggeration to say that the download function is the most valued feature within Ondoku.
Such an important download.
We have received inquiries like this.
In such cases, we will introduce how to solve the problem.
In Ondoku, when downloading, you can easily do so using the download button as shown in the image.
It is a very easy and simple mechanism.
You can also download text that has been read aloud once before from your history.
However, if an error occurs, you will not be able to download it as described here.
These five problems can be solved very easily.
We will show you how to solve them.
If an error occurs where the download button is not displayed even after clicking the "Read Aloud" button, there are two possible causes.
The download button may not be displayed due to compatibility with the network environment, PC antivirus software, etc. Please review your usage environment.
If the download button still does not appear, there is a high possibility of a server error, so please contact us via email through our inquiry form.
If the download button is displayed but the screen to choose a save location does not appear, it is an error on the user's browser.
First, open the settings screen from "chrome://settings" or the "Settings" menu.
Once you have opened the settings screen, please turn on downloads from the Google Chrome browser settings.
Search for "[Your Browser Name] download settings" and check the configuration method.
If an error message appears and you cannot download the desired audio, there are three possible causes.
The maximum number of characters allowed is 5,000 for free members. For paid members, it is between 200,000 and 1,000,000 characters depending on the plan.
When the number of characters that can be read aloud is exceeded, an error message saying "Reached the character limit for reading aloud" will play.
If you want to read aloud right away, please purchase a paid plan to add more characters.
In this case, the error message "Some kind of error has occurred" will play.
This type of error occurs when you try to read aloud text that includes special characters.
Please remove special characters and try reading aloud again.
Due to compatibility issues with the browser or network connection being used, an error saying "Some kind of error has occurred" may appear when trying to read aloud text on Ondoku.
In such cases, please:

Explains how to handle cases where an error occurs in Ondoku and text cannot be read aloud. Introduces check points divided into two categories: problems with the text being read and problems with the usage environment. Also provides guidance on how to contact us if the problem is not resolved.
This is often due to a simple mistake by the user.
Ondoku converts text to audio by clicking the "Read Aloud" button.
When reading many sentences in a row, it's easy to accidentally forget to press the "Read Aloud" button.
Since the download button is displayed, downloading it results in the phenomenon where the previous text is played.
This is a major cause.
Please remember to click the "Read Aloud" button.
Alternatively, you can download sentences previously read aloud from your history.
Please check if you can download normally from there.
If it sounds normal when listening on the web, the created download file is also normal.
Most likely, there is a high possibility of an issue with the audio player.
Most problems are solved by these two methods.
