User dictionary function is essential for reading Japanese sentences

Japanese book

I will tell you a little difficult story.

Japanese kanji are ideographic characters . Hiragana and Katakana in Japanese are phonetic characters .

It is one of the rare languages in which Japanese phonetic characters and ideographic characters are mixed.

What is an ideographic character?

One of the character classifications. A character in which each character has a certain meaning. Kanji and ancient Egyptian hieroglyphs. Character.

Therefore, even if the kanji is the same, there are many cases where the reading differs depending on the flow of sentences and phrases.

How to read "raw" is as follows.
Read aloud "Say" "Show"
Kun'yomi "Ikiru" "Ikasu" "Ike" "Umareru" "Umu" "Ou" "Haeru" "Hayasu" "Ki" "Nama"

How to read "below" is as follows.
Read aloud "ka" "ge"
Kun'yomi "Shimo" "Moto" "Sageru" "Sagaru" "Kudaru" "Kusu" "Give me" "Grate" "Oriru"

this is. It's a tremendous amount of work for text-to-speech software.

I predict it using algorithms to some extent and convert it to voice, but it is not perfect, so it can be wrong.

Romaji and other characters used in English are phonetic characters, not ideographic characters.

What is a phonetic character?

One of the character classifications. Characters that represent only sound, with each character having no meaning. Kana, Romaji, Sanskrit, etc. There are syllabaries and phoneme characters. Letters. Phonetic alphabet.

In the case of phonetic characters, the text-to-speech software only has to read it exactly as it is, so there is less trouble like in Japanese.

You can read it exactly as it is written, so there are almost no situations where you need a dictionary.

In a sense, Japanese is a language that makes sentence-reading software developers cry.

However, the dictionary function added this time must solve misreading and annoyance.

Please try using this convenient dictionary function!

This dictionary function is currently only available in Japanese. It cannot be used in other languages.

If you switch the language of the site display, the word dictionary disappears from the menu bar.

We are proud to continue to be the best text-to-speech software for you.

We look forward to your continued support of Ondoku .
