Why is English Pronunciation Checking Important? Learning Methods You Can Do with Free Sites

First, we will briefly explain why English pronunciation checking is important and recommend free learning methods!
The reason why Japanese people can't break away from Katakana English
Checking your pronunciation is essential for improving your English smoothly.
There is actually a reason why Japanese people struggle with English pronunciation.
That is, English has many more sounds than Japanese.
For example, the difference between "L" and "R."
"Light" and "Right" both become "ライト" when written in Japanese, but they are completely different sounds in English.
There are many other sounds that do not exist in Japanese, such as the difference between "B" and "V," or the "TH" sound where the tongue is placed between the teeth.
Many people may have learned a lot of grammar and vocabulary in school English classes but have hardly ever done pronunciation checks.
That is why many people are unable to break the habit of Katakana English.
To break away from Katakana English, we recommend performing regular English pronunciation checks.
By using free sites to check your English pronunciation, you can understand your weaknesses and improve efficiently.
Pronunciation checking is recommended for studying English enjoyably!
To make English learning more enjoyable, we recommend incorporating pronunciation checks into your studies.
When your pronunciation improves, conversations with foreigners become smoother.
By being able to pronounce accurately, what you want to say is properly conveyed, and the number of times you are asked "What?" will decrease.
Even those who previously felt they were bad at English conversation will find themselves wanting to use English more and more.
Additionally, your listening skills will improve as well.
This is because sounds you can pronounce correctly are easier to hear when someone else speaks them.
If you use English for work, you will be able to speak with confidence in meetings and presentations.
Of course, it is also effective for exam preparation such as TOEIC and Eiken.
Particularly in listening sections, knowing accurate pronunciation can help increase your score.
By making pronunciation checks a habit, you can improve your overall English skills.
To surely upgrade your English proficiency, speaking practice using free sites and apps is ideal.
Solve previous pronunciation learning problems with free sites and apps!
Traditional English pronunciation learning had many hurdles.
When attending an English conversation school, it is not uncommon for the monthly tuition alone to cost tens of thousands of yen.
Private lessons are even more expensive.
Time constraints are also a major issue.
Having to go to a classroom at a fixed time can make it difficult for busy working adults or students to continue.
Many people may have been unable to actively participate in speaking practice in group lessons because they were embarrassed to make mistakes in front of other students.
That's where free pronunciation check sites come in.
By using sites and apps, you can check your pronunciation anytime, anywhere, whenever you like.
Of course, there is no need to be embarrassed if you make a mistake.
Using free sites and apps can significantly lower the hurdles to English learning.
What is the new method for English pronunciation checking using the latest AI technology?

Easy pronunciation checks with the latest AI featuring native pronunciation
Currently, AI technology that can be used for English learning is developing rapidly.
One technology that has become particularly convenient is "text-to-speech technology."

What are the benefits of pronunciation checking using the latest AI?
Compared to previous learning methods, pronunciation checking methods using the latest AI have many benefits.
The biggest benefit is that it can be used for free!

Being able to progress with your learning at your own pace without worrying about others is very mentally relaxing.

After accessing the "Ondoku" website, first enter the text in the text box.

Any English text is OK, whether it's travel English or business English!
Select English in the language settings.
"Ondoku" can read out American English, British English, Australian English, and Indian English.
Select the English pronunciation you want to study.

There are many choices, but we recommend choosing a voice that you find easy to hear at first.

You have now generated audio for pronunciation checks and speaking practice.
Since you can download the audio files in MP3 or WAV format, we also recommend saving them to your smartphone or PC.
Why not try making audio teaching materials with "Ondoku" first?
Recommended Settings for Pronunciation Checks and Speaking Practice
When performing English pronunciation checks or speaking practice, settings for playing audio in apps on your smartphone or PC are also important.
First, adjust the volume so that the audio can be heard clearly.
If possible, we recommend using earphones or headphones.
You will be able to hear finer differences in sounds.
Preparation for recording is also important.
Using a recording app on your smartphone is sufficient, but checking how to use it beforehand will make your speaking practice smoother.
By setting up your environment in advance, you can proceed with your English learning efficiently.
Check word pronunciation first with sites and apps

It is effective to start English pronunciation practice at the word level.
Try starting your pronunciation checks and speaking practice with words containing sounds that Japanese people are particularly bad at.
To practice the difference between "R" and "L," words like "right" and "light" are recommended.
Have "Ondoku" read out the words and listen carefully to the generated audio.
It is important to listen many times while being conscious of the position of your tongue and the shape of your mouth.
For the "TH" sound, you can practice with words like "think," "thanks," and "through."
The key is to remember the sensation of letting the tip of your tongue lightly touch your teeth.
For the difference between "V" and "B," try practicing with "very" and "berry."
Learn physically the difference between the "V" sound, where the lower lip lightly touches the upper teeth, and the "B" sound, where both lips are pressed together.
When recording your own pronunciation, the trick is to pronounce the same word several times in a row and compare your best pronunciation with the model.
By checking pronunciation at the word level, you can solidify the foundation of your English pronunciation.
We recommend practicing a little every day utilizing free sites and apps.
Challenge yourself with speaking practice of phrases and sentences
Once you get used to word pronunciation, next challenge yourself with speaking practice of short phrases and sentences!
We recommend starting with short sentences of about 5 to 8 words.
- "How are you today?"
- "What time is it?"
Common expressions used in daily life are perfect for practice.
In sentence-level practice, intonation (the rise and fall of sound) is very important.
Use "Ondoku" audio to check basic patterns, such as the voice rising at the end of a question and falling at the end of a normal sentence.
Also, in English, words are often pronounced as if they are connected.
For example, "pick it up" sounds like "pi-ki-tap," or "want to" is pronounced as "wanna."
If you cannot pronounce it well, try lowering the audio speed.
Since "Ondoku" allows you to easily adjust the playback speed, you can acquire accurate pronunciation at a slow speed at first, and gradually move closer to natural speed.
Practical English conversation speaking practice with "Ondoku"
Once you get used to it, try speaking practice that is close to actual conversation.
Use "Ondoku" to read out dialogues assuming situations you might actually encounter, such as ordering at a restaurant, giving directions, or talking on the phone.
For example, for a conversation at a restaurant:
A: "Good evening. Do you have a reservation?"
B: "Yes, under the name Smith."
Create teaching materials by having "Ondoku" read out sentences like these.
By practicing speaking while checking the pronunciation of both sentences A and B, you can acquire practical conversational pronunciation.
In speaking practice, it is also important to practice expressions with emotion.
By practicing various emotional expressions, such as when you are happy, surprised, or disappointed, you can acquire more natural and rich English expressions.
Pronunciation checks in a dialogue format are ideal for improving actual communication skills.
Why not try conversation practice in various situations utilizing "Ondoku"?
Points for Effectively Proceeding with English Pronunciation Checks and Speaking Practice

How to effectively check pronunciation with free sites and apps?
The key to more effective pronunciation checking is to objectively evaluate your own pronunciation.
Record your own pronunciation and check if you can pronounce it well and how different it is from the model audio.
Specifically, focus on these four points:
- Accuracy of sound
- Intonation
- Rhythm
- Fluency
Try scoring and recording each on a 10-point scale.
By keeping records continuously, you can confirm your improvement progress numerically.
When checking your pronunciation, play the audio created with "Ondoku" and your recorded audio alternately to see where the differences are.
Make specific notes on which sounds are different and where the rhythm breaks down, then concentrate on practicing those parts next time.
By regularly recording and comparing, you can steadily improve your English pronunciation.
Common mistakes in English pronunciation and how to fix them
There are common patterns in pronunciation mistakes often seen in Japanese learners.
The first is adding extra vowels.
For example, it is common to pronounce "student" as "su-tu-den-to" or "Christmas" as "ku-ri-su-ma-su."
In such cases, listen to accurate audio and focus your speaking practice on being conscious of consonant-only sounds.
Also, it is common to be unable to pronounce the final sound of a word well.
Make an effort to clearly pronounce the final "d" in "good" or the final "k" in "make."
The distinction between long and short sounds is also a difficult point for Japanese people.
There are many words where the meaning changes depending on the length of the vowel, such as "sheep" and "ship."
We recommend practicing pronunciation intensively using English audio created with "Ondoku".
Pronunciation checks along with shadowing practice
Shadowing is a speaking practice method where you speak the same content slightly after listening to the audio.
It is a very effective English learning method that can train pronunciation and listening at the same time.
With "Ondoku", you can create high-quality audio materials for shadowing.
In shadowing, you perform speaking practice in stages while listening to the audio.
First, listen only to the audio to grasp the content and rhythm.
Next, pronounce along with the audio while looking at the text.
Finally, shadow without looking at the text, relying only on the audio.
The key is also to start with short sentences first and gradually challenge yourself with longer sentences or complex content.
Since "Ondoku" allows you to adjust the playback speed, you can start shadowing at a slow speed according to your level.
Once you can do it smoothly at normal conversation speed, try challenging yourself with a slightly faster setting!
By recording your shadowing voice and performing pronunciation checks, synergistic effects can be expected.
Shadowing is also effective for acquiring a sense of rhythm in English.
Why not start shadowing using "Ondoku" English reading audio?
