The text-to-speech software Ondoku can read up to 5,000 characters for free. In addition, with paid plans, you can read up to 1 million characters per month. Text read in high-quality audio can be output as audio files (.mp3) and commercial use is also possible.

Previously, we received a question like this through our inquiry form.

"It states that the Basic Plan is equivalent to two novels, but is this true?"
"Can it really read the character count of about two paperback novels?"

Admittedly, verifying whether the 200,000 characters read by Ondoku actually equals two paperback novels is quite a laborious task.

So this time, we will verify whether Ondoku's Value Plan truly covers about two novels.

How many characters are in a paperback novel?

Reading a book

When you try to read a paperback novel, it usually takes a lot of time.

Reading silently requires an average of 2 to 6 hours.

Many people might think that reading a novel takes a long time, but very few have probably ever counted how many tens of thousands of characters there are.

To begin with, just how many tens of thousands of characters are in a novel?

Let's search for "novel character count" on the internet.

According to Ishida Printing Co., Ltd.:

The number of characters required for one book and the book's spine width
A standard guideline is 100,000 to 120,000 characters for a paperback, and 80,000 to 120,000 characters for a Shinsho (pocket-sized book).
250 sheets of 400-character manuscript paper equals 100,000 characters. One page of a paperback or Shinsho is about 600 characters, so 100,000 characters is 167 pages.

Since headings, line breaks, paragraph breaks, and illustrations are included, the actual character count will be lower.

That is the case.

Of course, the character count varies greatly depending on the book.

For example, the bestseller "Harry Potter and the Sorcerer's Stone" is said to have about 360,000 characters in one volume. If you thought it took a long time to read, it's definitely because of the significant character count.

Books with such a large number of characters like Harry Potter and the Sorcerer's Stone are rare.

It is said that a general paperback novel has about 100,000 characters.

Ondoku allows for 200,000 characters to be read. There is no doubt that you can read about two paperback novels.

* The character count for paperback books is based on Japanese.

Tips for actually reading novels with Ondoku

Headphones and a book

So, can you actually read two novels with Ondoku?

A problem arises when you actually try to read a novel with Ondoku.

That is, if you make even a small correction to the text to be read or try to re-read it, those characters are counted, meaning it might not actually be possible to read exactly two full novels.

In Ondoku, when reading a similar sentence again, if there is a change such as:

  • Even a single character being different
  • Even a single setting being changed

It is recognized as a different sentence and the character count increases.

Therefore, to read while minimizing the character count from corrections as much as possible, you may need:

  • Decide on settings in advance by reading short sentences
  • Continue reading as is without worrying about or correcting misreadings

It seems that ingenuity and tolerance will be necessary.

By reducing the loss from corrections and misreadings as much as possible, you will be able to actually read two books.

With Ondoku, anyone can easily create an audiobook!

We introduce how to create an audiobook in this article, so please take a look at it as well.

At Ondoku, we also want to reduce misreadings as much as possible.

We take pride in Ondoku being the best text-to-speech software for you.

Thank you for your continued support.
