Why not try using convenient apps for iPhone and iPad (iOS) by referring to this article?

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

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

What is an iPhone automatic text-to-speech app? The mechanism for converting text to speech on a smartphone

A convenient AI reading app that can be used on iPhone or iPad iOS.

The automatic 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 voice, and with recent advances in AI technology, incredibly natural reading has become possible.

Unlike previous mechanical voices, modern automatic text-to-speech apps have intonation and pauses that are more human-like, and an increasing number of them achieve a quality that is not tiring even when listening for long periods.

In particular, reading apps utilizing the latest AI technology achieve a natural voice as if an actual narrator were reading.

Limits of the standard reading function built into iPhone

iPhone comes with a standard reading function, but there are several inconvenient points to this function.

First, the operation is complex.

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

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

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

Furthermore, since standard functions cannot save the read voice as a file, it is inconvenient if you want to listen back to it later.

In this way, the standard function of iPhone is designed primarily as an accessibility feature, and there are limitations to its functionality.

For more comfortable automatic text-to-speech on iPhone, 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 automatic text-to-speech services available for iPhone and iPad (iOS): app-type and browser-based type.

The app-type is the kind you download from the App Store; while it takes effort to install, it has the advantage of being usable offline.

On the other hand, the browser-based type (web app type) is the kind you access directly from a browser such as 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 iPhone.

The biggest advantage is being able to 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 option.

What can you do with text-to-speech? Recommended ways to use iPhone reading apps

iPhone automatic text-to-speech apps can be utilized in many situations.

During commutes, you can make effective use of travel time by having articles, blogs, or e-books read to you.

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

In language learning, since you can listen to accurate pronunciation repeatedly, it helps improve listening and speaking skills.

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 text displayed on the iPhone screen makes access to digital content easier.

In this way, the iPhone reading app is a very convenient tool that supports our lives in various scenes.

It is a long-established app that has been around for a long time.

It supports files in various formats (PDF, Word, EPUB, web pages, etc.) and can read aloud various documents saved on your iPhone.

However, note that the basic app is paid, and additional voices require separate purchases, so costs may add up.

Because learning support features are extensive—such as text highlighting, reading speed adjustment, and automatic scrolling—it is also recommended for students studying with an iPhone.

Since it can be used offline, another big advantage is that you can use it without worrying about iPhone data usage.

3. iPhone Standard Reading Function: The benefit is being able to read text aloud automatically without installation

The reading function (accessibility feature) standardly built into iPhone and iPad can also be utilized as a fully functional reading app.

It can be used by turning on "Accessibility" -> "Spoken Content" -> "Speak Screen" from the iOS Settings app.

The biggest advantage is that you don't need to install additional apps, so it doesn't consume iPhone storage capacity.

Reading speed and voice types can also be changed from the settings, but options are limited compared to third-party apps.

Also, a disadvantage compared to dedicated automatic text-to-speech apps is that it is difficult to save as an audio file.

While the free version allows you to use basic reading functions, high-quality voices and advanced features are only available in paid plans.

The iPhone app is easy to use with a simple design, and can be comfortably operated even in a mobile environment, from loading text to converting to MP3.

Because the cloud synchronization function allows you to continue work on both iPhone and computer, it is convenient when using across devices.

Speechy is a reading app characterized by natural reading voices that utilize AI voice technology.

Since the UI for iPhone is sophisticated and the operational feel is smooth, even beginners can master it intuitively.

While a free version is provided, high-quality voices and advanced features are only available with a paid subscription.

Developing from the background of being created for people with learning disabilities, it is also characterized by extensive features to aid understanding, such as text highlighting.

The function to directly scan and read printed materials using the iPhone camera is also convenient.

However, since it is a monthly subscription, the point of continuous cost should be considered.

6. Yukkuri Bouyomi Talk: An app that can read aloud with Yukkuri voices on iPhone

Main functions of the app include setting reading text, starting and stopping reading, changing speed, repeat settings, selecting voice types, and monotone settings.

How to Master "Ondoku" on iPhone

For first-timers! A 3-step guide to using "Ondoku" on iPhone

"Ondoku" can be used on iPhone or iPad as easily as on a computer.

First, access the Ondoku official website in the Safari browser of your iPhone or iPad.

Next, paste the text you want to read into the input field or enter it directly.

Then, just by tapping the "Read" button, high-quality automatic text-to-speech will begin.

Once the reading process is complete, the read voice will be automatically played.

"Ondoku" can be used for free for up to 1,000 characters without registration, but if you register your email address, the free quota expands to 5,000 characters, so registration is recommended if you want to read long texts.

Audio can be downloaded in MP3 format, so you can save the read voice to your iPhone or iPad and listen to it offline.

How to add to the iPhone/iPad home screen and use it like an app

Although "Ondoku" is a browser-based service, it can also be used like an app on iPhone or iPad.

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

Select "Add to Home Screen" from the displayed menu.

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

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

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 address bars are not displayed, allowing for more focused use.

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

How to customize voice and reading speed

In "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" dropdown menu, and for Japanese, you can choose from 17 types of voices.

The reading speed can be adjusted with the "Speed" slider, and can be changed from 0.5x (slow) to 2.0x (fast).

The pitch of the voice can also be adjusted with the "Pitch" slider, allowing for changes to lower or higher voices.

Because such detailed adjustments are possible, you can find voice settings to your liking that are not tiring even if you keep listening for long periods on your iPhone.

"Ondoku" is a multi-language supported text-to-speech web app for iPhone

Another point is that "Ondoku" supports multiple languages.

Languages can also be selected from the dropdown menu like this.

Since "Ondoku" allows you to change the playback speed, it is ideal for language learning.

In particular, in language learning, listening at a slow speed makes it easier to catch, and once you get used to it, you can increase the speed for practical listening practice.

Since the UI design is easy to operate even on the small screen of an iPhone, the charm is also being able to change settings without stress.

In this way, "Ondoku" is convenient and easy to use!

When looking for an iPhone reading method, why not experience "Ondoku" first?

How to Choose an Automatic Text-to-Speech App for iPhone and iPad (iOS) Users

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

Choose based on voice quality and naturalness

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

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

Reading apps like "Ondoku" that use the latest AI technology read with natural intonation as if a human were speaking, so the feature is that your ears are less likely to get tired even after long periods of listening.

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

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

Compare ease of use and UI

Considering operation 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, ease of access to frequently used functions, text input methods, and methods for controlling the reading voice are important factors that influence ease of use on an iPhone.

By choosing an app with a UI optimized for the iPhone display size, you can utilize the reading function without stress.

Choose based on differences in pricing plans and cost-performance

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

While some free apps provide sufficient functionality, there are also cases where you seek advanced functions and sophisticated voice quality unique to paid apps.

Services like "Ondoku" that can be used for free can be said to excel in cost-performance.

Among iOS apps for iPhone and iPad, not a few require payment for actual use even if they are described as free versions.

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

Also check the impact on battery consumption and performance

Battery life of an iPhone or iPad is very important.

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

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

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

If you plan on long-term reading, 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 practical ways to utilize iPhone/iPad reading apps?

Make effective use of commute time! Easily collect information while on the move

iPhone reading apps are a powerful tool for making effective use of commuting or 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 a browser-based reading service like "Ondoku" and copying and reading the text of news articles or blogs you are interested in before leaving for work, you can listen to them while commuting.

Even with just a little time during a commute, you can secure dozens of minutes of learning time in a day using a reading app.

Of course, it is also recommended for those commuting by car.

Using a reading app allows you to safely obtain information, so you don't have to waste time.

Utilize iPhone text-to-speech apps for language learning!

iPhone reading apps are also very effective for language learning.

If you use a multi-language supported reading service like "Ondoku", you can have foreign language text read aloud with accurate pronunciation.

Listening to the same sentence over and over leads to improved listening skills and the acquisition of natural pronunciation.

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

Because the iPhone reading app allows for speed adjustment, beginners can start slowly, and once used to it, they can increase the speed for practical listening practice.

If combined with a foreign language learning app, you can listen to phrases and grammar learned in the app within actual context, allowing for more effective learning.

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

Efficiently check business documents and emails

For business people, the iPhone reading app becomes a powerful tool for streamlining the task of checking emails and documents.

If you have long business emails or reports read aloud by apps such as "Ondoku", you can take in information not only visually but also auditorily, deepening your understanding of the content.

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

By listening to audio, it becomes easier to notice nuances of expression or awkwardness that you might not have noticed with text alone.

In particular, in proofreading work, small mistakes that are often overlooked just by reading with eyes can often be discovered by listening to audio.

By combining it with iPhone 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 people who travel a lot, the iPhone reading app can be called an essential tool for making effective use of time.

Achieve "multi-task reading"! Input information during housework or exercise

The iPhone reading app enables "multi-task reading," taking in information hands-free during housework or exercise.

Even while doing chores such as cooking, cleaning, or laundry, you can listen to the contents of books or articles using a reading app like "Ondoku".

During exercise such as jogging or walking, if you combine an iPhone with wireless earphones, you can 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 actually don't have time for reading using eyes, the iPhone reading app provides precious "reading time."

Utilizing every gap in daily life, such as morning preparation or routines before bed, information can be taken in efficiently.

First, why not try making an audiobook with "Ondoku"?

Troubleshooting the Reading Function of iPhone and iPad

Causes and solutions for "No sound" trouble

While using a reading app on iPhone or iPad iOS, a trouble where sound is not produced may 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 unit is in the orange state, silent mode is enabled.

Next, check if the volume is set appropriately.

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

If you are using Bluetooth earphones or speakers, it is also necessary to check if they are correctly connected and if the sound is being output to another device.

For browser-based services like "Ondoku", check if sound is permitted in the browser settings.

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

If the problem is not resolved after these checks, restarting the iPhone often solves the problem.

How to adjust when Japanese reading sounds unnatural

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

Services like "Ondoku" that use the latest AI technology are good at natural Japanese reading, but there are also tips to further improve naturalness.

If the way a kanji is read is wrong, it may improve if you write it in hiragana or katakana.

For example, if "今日は雨です" (Kyō wa ame desu) is read unnaturally, it may be read correctly if you enter "きょうはあめです."

The placement of punctuation marks is also important.

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

Trying a different reading voice is also recommended.

Since "Ondoku" allows you to easily change the voice type, you can quickly find a voice that sounds more natural.

Please also see here for how to adjust the voice.

Optimal settings to reduce battery consumption

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

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

It can be easily adjusted from the Control Center.

By locking the screen and turning off the display during reading, you can further save battery.

For browser-based services like "Ondoku", downloading the read voice and playing it later in a music app etc. can suppress battery consumption.

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

This is particularly effective if you plan on long-term reading.

It is also effective to check which apps are consuming battery from "Settings" -> "Battery" of the iPhone or iPad and close unnecessary apps.

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

Summary: Why not try utilizing text-to-speech apps on iPhone and iPad?

When using the automatic text-to-speech function of an iPhone or iPad for the first time, we recommend starting from browser-based services such as "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 at first and check the operational feel of reading and the naturalness of the voice.

Once you get used to it, it is recommended to gradually challenge yourself to read long texts and various contents, and find a usage method that suits your purpose.

Why don't you also try using text-to-speech apps on iPhone or iPad, starting with "Ondoku"?
