Basic Knowledge of Auto Text-to-Speech Apps for iPhone and iPad (iOS)

What are the features of iPhone's auto text-to-speech?

First, we will briefly explain auto text-to-speech apps for iPhone and iPad (iOS).

What is an iPhone Auto Text-to-Speech App? The Mechanism of Converting Text to Speech on a Smartphone

Convenient AI reading apps available for iOS on iPhone and iPad.

The auto text-to-speech technology used in these AI apps is called "TTS (Text-to-Speech)."

This is a technology that converts text data into human speech, and with recent advances in AI technology, incredibly natural reading has become possible.

Unlike previous mechanical voices, an increasing number of modern auto text-to-speech apps achieve human-like quality in terms of intonation and pausing, making them less tiring to listen to for long periods.

In particular, reading apps utilizing the latest AI technology achieve natural speech that sounds as if an actual narrator is reading.

There are Limitations to the Standard Reading Function Built into the iPhone

The iPhone comes with a standard reading function, but this function has several inconvenient points.

First, the operation is complex.

It needs to be enabled from the Accessibility settings, which is a bit of a high hurdle for beginners.

Furthermore, the quality of the reading voice is inferior compared to dedicated apps.

It can only read in a voice that feels a bit monotonous for listening to long texts continuously.

Additionally, with the standard function, you cannot save the read speech as a file, which is inconvenient if you want to listen to it again later.

In this way, the iPhone's standard function is designed primarily as an accessibility feature and has limitations.

To read text automatically on iPhone more comfortably, it is recommended to use dedicated AI reading services or apps.

What is the Difference Between iOS App-type and Browser-based Type?

There are two types of auto text-to-speech services available for iPhone and iPad (iOS): app-type and browser-based type.

The app-type is the type you download and use from the App Store; it takes some effort to install but has the advantage of being usable offline.

On the other hand, the browser-based type (web app type) is the type you access directly from a browser like Safari, and its appeal is that it can be used immediately without installation.

For example, Ondoku is a representative example of a browser-based type (web app type), and can be accessed immediately from Safari on an iPhone.

The biggest advantage is that you can use high-quality reading functions without tedious installation work.

For iPhone users concerned about storage capacity, a browser-based reading service that can be used without installation is a very convenient choice.

What Can You Do with Text-to-Speech? Recommended Ways to Use iPhone Reading Apps

It is also possible to input information without using your hands while doing housework or cooking.

In language learning, it is useful for improving listening and speaking skills because you can listen to accurate pronunciation repeatedly.

In business settings, checking long emails or reports by voice can reduce eye strain while processing information efficiently.

Furthermore, for people with visual impairments or the elderly, reading aloud the text displayed on the iPhone screen makes accessing digital content easier.

In this way, iPhone reading apps are very convenient tools that support our lives in various scenes.

Then, simply tap the "Read" button to start the high-quality auto text-to-speech.

First, tap the "Share" button (the icon of a square with an upward arrow) at the bottom of the Safari screen.

From the displayed menu, select "Add to Home Screen."

The edit screen will open, so tap "Add."

The Ondoku icon has now been added to the home screen of your iPhone or iPad, and you can now access it with just one tap, just like an app.

By using this method, you can use Ondoku more comfortably without having to enter the URL in the browser every time.

Accessing from the home screen icon opens it in "App Mode," where Safari tabs and the address bar are not displayed, allowing for more focused use.

This method is especially recommended for those who want to make effective use of screen space on their iPhone or iPad.

How to Customize Voice and Reading Speed

With Ondoku, you can easily customize the voice and reading speed even from an iPhone or iPad.

The type of reading voice can be selected from the "Voice" drop-down menu, and for Japanese, you can choose from 17 types of voices.

How to Choose an Auto Text-to-Speech App for iPhone/iPad (iOS) Users

Next, we will explain how to choose an auto text-to-speech app for iPhone and iPad (iOS).

Choose by Voice Quality and Naturalness

When choosing a reading app to use on iPhone or iPad (iOS), one of the most important points is voice quality and naturalness.

Mechanical reading makes long-term use painful, and unnatural intonation makes understanding the content difficult.

Reading apps like Ondoku, which use the latest AI technology, read with natural intonation as if a human were speaking, so a characteristic is that your ears are less likely to get tired even during long listening sessions.

Especially in Japanese reading, it is important whether it can appropriately handle language-specific complexities such as how to read kanji and the handling of particles.

If you plan to read a lot of Japanese content on your iPhone, we recommend choosing an app that is strong in Japanese processing.

Compare Ease of Use and UI

Considering that you will be operating on the small screen of an iPhone, a reading app with a simple and intuitive UI design is desirable.

Apps that require complex settings or cumbersome operations are not suitable for use on a smartphone.

Browser-based services like Ondoku are designed with a simple interface so that even beginners can use them without hesitation.

Also, the ease of access to frequently used functions, text input methods, and reading voice control methods are important factors that affect ease of use on an iPhone.

By choosing an app with a UI optimized for the iPhone's display size, you will be able to utilize the reading function without stress.

Choose by Differences in Pricing Plans and Cost-Effectiveness

Reading apps for iPhone and iPad have various pricing structures, from free ones to expensive monthly subscriptions.

While some free apps provide sufficient functions, there may be cases where you seek advanced functions or refined voice quality unique to paid apps.

Services like Ondoku, which can be used for free, can be said to be excellent in cost-performance.

Many iOS apps for iPhone and iPad, even if labeled as free versions, require payment for actual use.

It is important to check in advance whether the truly necessary functions can be used for free, or if there is a possibility that an upgrade to a paid plan will be needed in the future.

Check Battery Consumption and Impact on Performance

The battery life of an iPhone or iPad is very important.

Some reading apps consume a large amount of battery due to background processing or always-on execution functions.

In particular, apps that perform advanced voice processing tend to put a load on the iPhone processor, leading to faster battery consumption.

Lightweight services like browser-based Ondoku perform processing only when needed, so it can be said that the impact on iPhone battery life is relatively small.

If you plan on long reading sessions, we recommend choosing an app with low battery consumption or taking measures such as carrying a charger or mobile battery when going out.

What are the Practical Ways to Use iPhone/iPad Reading Apps?

Make Effective Use of Commuting Time! Easily Collect Information While Moving

iPhone reading apps are powerful tools for making effective use of commuting and school travel time.

Even if it is difficult to open a book and read in a crowded train or bus, you can obtain information via voice using earphones.

By using browser-based reading services like Ondoku to copy and have the text of news articles or blogs you are interested in read before leaving for work, you can listen to them during your commute.

Even in the short time during a commute, you can secure tens of minutes of learning time a day by using a reading app.

It is also, of course, recommended for those commuting by car.

Using a reading app allows you to obtain information safely, so you don't end up wasting time.

Utilize iPhone Text-to-Speech Apps for Language Learning!

iPhone reading apps are also very effective for language learning.

Using multi-language compatible reading services like Ondoku, you can have foreign language texts read to you with accurate pronunciation.

Listening to the same text repeatedly leads to improved listening skills and the acquisition of natural pronunciation.

The learning method called shadowing, where you read aloud yourself while having the foreign language text read to you, is also recommended.

If combined with language learning apps, you can listen to phrases and grammar learned in the app within actual context, enabling more effective learning.

The great appeal of reading apps is that you can create a learning environment with just an iPhone, as if a native speaker were right next to you.

Efficiently Check Business Documents and Emails

For business professionals, iPhone reading apps can be powerful tools for streamlining the process of checking emails and documents.

Having long business emails or reports read by apps like Ondoku allows you to take in information through hearing as well as sight, deepening your understanding of the content.

By preparing while having materials read to you before a meeting, you can input information efficiently.

Listening by voice makes it easier to notice nuances of expression or awkwardness that you might not have noticed with text alone.

Especially in proofreading work, small mistakes that are often overlooked when reading by eye can often be discovered by listening to the voice.

By combining with iPhone's Siri shortcuts, it is also possible to have the latest emails read aloud with just a voice command like "Read today's emails."

For business professionals who travel a lot, iPhone reading apps can be said to be an essential tool for making effective use of time.

Achieve "Reading While Doing"! Information Input During Housework or Exercise

iPhone reading apps enable "reading while doing," taking in information hands-free during housework or exercise.

Even while doing housework such as cooking, cleaning, or laundry, you can listen to the content of books or articles using reading apps like Ondoku.

During exercise such as jogging or walking, combining an iPhone with wireless earphones allows you to input information without using your eyes.

The simple operability of Ondoku is also suitable for a bit of operation between housework or exercise.

For busy housewives or dual-income households who cannot actually take the time to read using their eyes, iPhone reading apps provide precious "reading time."

You can efficiently take in information by utilizing all the gap times in daily life, such as morning preparation or the routine before bed.

Troubleshooting iPhone/iPad Reading Functions

Causes and Solutions for "No Sound" Trouble

While using a reading app on iPhone or iPad iOS, trouble where no sound comes out can occur.

The first thing to check is whether the iPhone or iPad is in "Silent Mode."

If the silent switch on the side of the main body is in the orange state, silent mode is enabled.

Next, confirm that the volume is set appropriately.

You can adjust it with the volume buttons on the iPhone or iPad or check from the Control Center.

If you are using Bluetooth earphones or speakers, it is also necessary to confirm that they are correctly connected and whether the audio is being output to another device.

For browser-based services like Ondoku, please confirm whether audio is permitted in the browser settings.

Check if it is set to "Allow" in "Website Settings" → "Auto-Play" from Safari settings.

If these checks do not solve the problem, restarting the iPhone often resolves the issue.

Adjustment Methods When Japanese Reading is Unnatural

If the Japanese reading on the iPhone feels unnatural, there are several adjustment methods.

While services using the latest AI technology like Ondoku are good at natural Japanese reading, there are tips to further improve naturalness.

If the reading of kanji is wrong, it may improve if you write it in hiragana or katakana.

For example, if "今日は雨です" is read unnaturally, entering "きょうはあめです" may result in correct reading.

The placement of punctuation is also important.

By putting punctuation marks in appropriate positions, it can be read with more natural intonation and pauses.

Trying to change the reading voice is also recommended.

With Ondoku, you can easily change the type of voice, so you can immediately find a voice that sounds more natural.

Please also see here for how to adjust the voice.

Methods you should try when you want to adjust intonation and inflection in Ondoku

If you want to adjust intonation even a little in Ondoku, you can adjust intonation and inflection to some extent by making full use of hiragana, katakana, kanji, alphabets, and punctuation marks.

Optimal Settings to Restrain Battery Consumption

When using a reading app on an iPhone or iPad, there are several settings to restrain battery consumption.

First, lowering the screen brightness can significantly restrain battery consumption.

It can be easily adjusted from the Control Center.

During reading, you can further save battery by locking the screen and turning off the display.

For browser-based services like Ondoku, you can restrain battery consumption by downloading the read speech in advance and playing it later in a music app.

Enabling Low Power Mode limits background processing and automatic updates, improving battery life.

This is especially effective if you plan on long reading sessions.

It is also effective to check which apps are consuming battery from iPhone/iPad "Settings" → "Battery" and close unnecessary apps.

Also, since battery consumption tends to be lower when connected to Wi-Fi than during mobile data communication, we recommend using it in a Wi-Fi environment if possible.

Summary: Why Not Utilize Text-to-Speech Apps on iPhone/iPad?

When using iPhone or iPad auto text-to-speech functions for the first time, we recommend starting with browser-based services like Ondoku.

Because it can be easily tried without installation, you can experience the basic usage and convenience of the reading function.

Start with short sentences first to check the operational feel of the reading and the naturalness of the voice.

Once you get used to it, we recommend gradually challenging long texts and various contents and finding a way to use it that suits your application.

Why don't you also try using text-to-speech apps for iPhone and iPad, including Ondoku?
