Why is checking your English pronunciation important? How to study on free sites
First, we will briefly explain why checking your English pronunciation is important and introduce some recommended free learning methods!
Why Japanese people can't get away from katakana English
Checking your pronunciation is an important part of improving your English .
There is actually a reason why Japanese people have trouble with English pronunciation.
That is, English has more sounds than Japanese .
For example, the difference between "L" and "R".
"Light" and "Right" both sound "light" when written in Japanese, but they are completely different sounds in English.
There are also many other sounds that do not exist in Japanese, such as the difference between "B" and "V" and the "TH" sound made by placing the tongue between the teeth.
Many people may have learned a lot of grammar and vocabulary in their English classes at school, but have rarely ever checked their pronunciation.
That's why many people are unable to break the habit of using katakana English.
A good way to get away from katakana English is to regularly check your English pronunciation.
By using a free website to check your English pronunciation , you can identify your weak points and improve them efficiently .
We recommend pronunciation checks to make studying English fun!

Even those who have felt uncomfortable speaking English in the past will find themselves wanting to try using it more and more.
It also improves your listening skills .

Recommended settings for pronunciation check and speaking practice
When checking your English pronunciation or practicing speaking, it's also important to set up the audio playback on your smartphone or PC app.
First, adjust the volume so that you can hear the audio clearly.
If possible, we recommend using earphones or headphones.
You can hear the subtler differences in sound.
Preparation for recording is also important.
Using a recording app on your smartphone will be sufficient, but if you learn how to use it in advance, you'll be able to practice speaking smoothly.
By setting up your environment in advance, you can progress through your English studies more efficiently.
First, check the pronunciation of words on the website or app
When practicing English pronunciation, it is effective to start at the word level.
Let's start by checking your pronunciation and practicing speaking with words that contain sounds that Japanese people have particular difficulty with .
If you want to practice the difference between "R" and "L", words like "right" and "light" are recommended.
Read the word out loud in Ondoku and listen carefully to the audio generated.
It is important to listen repeatedly, paying attention to the position of your tongue and the shape of your mouth.
You can practice the "TH" sound with words like "think," "thanks," and "through."
The key is to get used to the sensation of lightly touching the tip of your tongue to your teeth.
To practice the difference between "V" and "B," try "very" and "berry."
Get used to the difference between making a "V" sound by lightly touching your lower lip to your upper teeth, and making a "B" sound by bringing both lips together.
When recording yourself, a good idea is to say the same word several times in a row and compare your best pronunciation with the example .
By checking pronunciation at the word level, you can solidify the foundations of English pronunciation.
We recommend using free websites and apps to practice a little bit every day.
Challenge yourself to practice speaking phrases and sentences
Once you get used to the pronunciation of words, try practicing speaking short phrases and sentences !
It's recommended that you start with short sentences of 5-8 words .
- "How are you today?"
- "What time is it?"
Expressions that are commonly used in everyday life are perfect for practice.
When practicing at the sentence level, intonation (the rise and fall of sounds) is very important.
We use the audio from "Ondoku" to check your pronunciation of basic patterns, such as rising word endings in questions and falling word endings in normal sentences.
Also, in English, words are often pronounced together.
For example, "pick it up" sounds like "pickitappu" and "want to" is pronounced "wana."
If you are having trouble pronouncing the words properly, try slowing down the audio speed.
Ondoku's playback speed can be easily adjusted, so you can start out practicing at a slow speed to get the pronunciation right, and then gradually work your way up to a natural speed.
Practice English conversation with "Ondoku"
Once you get used to it, try practicing speaking in a way that is closer to real conversations .
Ondoku reads out dialogue based on real-life situations, such as ordering at a restaurant, getting directions, and having a phone conversation .
For example, a conversation in a restaurant:
A: "Good evening. Do you have a reservation?"
B: "Yes, under the name Smith."
We create teaching materials by reading sentences like the one above aloud using Ondoku .
By practicing speaking both sentences A and B while checking your pronunciation, you can acquire practical conversational pronunciation.
When practicing speaking, it is also important to practice expressing emotion .
By practicing expressing a variety of emotions, such as happiness, surprise, and disappointment, you can acquire more natural and rich English expressions.
Checking pronunciation in dialogue format is ideal for improving real-world communication skills.
Why not try using "Ondoku" to practice conversation in a variety of situations?
Tips for effectively checking your English pronunciation and practicing speaking
How can you effectively check your pronunciation using free sites and apps?
The key to checking your pronunciation more effectively is to objectively evaluate your own pronunciation .
Record yourself and check if your pronunciation is good and how it differs from the audio in the study material.
in particular,
- Sound accuracy
- intonation
- rhythm
- Fluency
Pay attention to the following four points.
Give each one a score out of 10 and keep a record of it.
By keeping continuous records, you can see your progress in improvement in numbers.
To check your pronunciation, play the audio created with Ondoku and the recorded audio alternately to see what the differences are.
Take specific notes of which notes are different and where the rhythm is off, and then focus on practicing those parts next time .
By recording yourself regularly and comparing your pronunciation, you can steadily improve your English pronunciation.
Common mistakes in English pronunciation and how to fix them
There are common patterns in the pronunciation mistakes commonly made by Japanese learners.
The first is adding an extra vowel .
For example, people often pronounce "student" as "student" and "Christmas" as "kurumasa ."
In such cases, try listening to accurate audio and focusing on speaking practice, focusing on consonant sounds only.
They also often have trouble pronouncing the final sounds of words.
Make sure to pronounce the final "d" in "good" and the final "k" in "make" clearly.
Distinguishing between long and short sounds is also a difficult point for Japanese people.
There are many words whose meaning changes depending on the length of the vowel, such as "sheep" and "ship."
We recommend that you focus on practicing your pronunciation by using the English audio created with "Ondoku."
Shadowing practice and pronunciation check
Shadowing is a speaking practice method in which you listen to an audio recording and then repeat the same content after a short delay .
This is a very effective English learning method that allows you to improve your pronunciation and listening skills at the same time.
With Ondoku , you can create high-quality audio materials for shadowing.
In shadowing, you practice speaking in a step-by-step manner while listening to audio.
First, listen to just the audio to understand the content and rhythm .
Next, look at the sentence and pronounce it along with the audio .
Finally, you will practice shadowing without looking at the text, relying only on the audio .
The key is to start with short sentences and gradually work your way up to longer sentences and more complex content .
Ondoku allows you to adjust the playback speed, so you can start shadowing at a slow speed that suits your level.
Once you can speak fluently at normal conversation speed, try a slightly faster setting!
You can expect a synergistic effect by recording your shadowing audio and checking your pronunciation.
Shadowing is also effective in developing a sense of English rhythm.
