In this article, for those of you in that situation, we will introduce **alternative solutions** in an easy-to-understand way for when **VOICEVOX cannot be used on iPhone (iOS) or Android smartphones**!
VOICEVOX, a high-performance speech synthesis software that can be used for free, is very popular, isn't it?
Many of those thinking about starting video production might want to use VOICEVOX on their own smartphones.
However, **VOICEVOX is software exclusively for PC, and there is no official smartphone app.**
Therefore, it is not possible to run the original VOICEVOX on an iPhone (iOS) or Android smartphone alone.
So this time, for those who wanted to use VOICEVOX on a smartphone, we will introduce the best alternative method!
In this article, we will thoroughly explain:
- Reasons why VOICEVOX cannot be used on iPhone/Android smartphones

Can VOICEVOX be used on iPhone or Android smartphones? Alternative apps explained

First, we will explain the reasons why the official VOICEVOX app cannot be used on iPhone (iOS) or Android smartphones, and alternative methods.
Conclusion: There is no official VOICEVOX smartphone app
In conclusion, **even if you search for "VOICEVOX" or "Zundamon" on the iPhone (iOS) App Store or Android Google Play, you cannot download the official VOICEVOX app.**
This is because VOICEVOX is an **app developed for PC** such as Windows, Mac, and Linux.
VOICEVOX is an app that can synthesize easy-to-listen-to audio, but it requires a certain level of specs.
Also, the voice adjustment functions for reading text are designed based on the assumption of operation on a PC.
In this way, a **PC is required** to use the voices of Zundamon, Shikoku Metan, or Kasukabe Tsumugi to read aloud in VOICEVOX.


But there are many cases where you want to create audio on an iPhone or Android smartphone instead of a PC, right?
It's okay!
In such cases, there is a recommended **alternative method that doesn't require installation and allows you to easily synthesize audio using only your smartphone.**
Ondoku is recommended as a VOICEVOX alternative! [Free, No Installation Required]
We definitely want you to try a text-to-speech app that can serve as an alternative to VOICEVOX.
The recommended one is the AI text-to-speech app "Ondoku"!
Ondoku is a web app that can be used from a browser.
**No smartphone app installation is required**; you can easily read text aloud and download it **just by accessing the website from your browser.**
Furthermore, it **supports reading long texts**, and you can read up to 5,000 characters of text for free!
Using very high-quality AI voices, you can create attractive videos using only your smartphone.
When you want to post videos to YouTube or TikTok using only your smartphone, why not start by using **Ondoku**, which is **free and requires no installation**?
Thorough comparison of VOICEVOX and Ondoku! Can it be used on a smartphone instead?

Here, let's compare the PC version of VOICEVOX and **Ondoku**, which can be used in a smartphone browser, in detail!
By understanding the characteristics of each, you will clearly see which one is more suitable for your purposes.
[PC, iPhone, Android] Supported devices and installation methods?
First, supported devices.
VOICEVOX is basically for PC use only.
In contrast, **Ondoku** can be used on any device that runs a browser, including PCs, **iPhones, iPads (iOS), Android smartphones, and tablets.**
Also, **VOICEVOX requires downloading and installing the software.**
Since the file size is large, especially the data capacity for each character, it is recommended to download it using a high-speed connection.
In some cases, installation may take some time.
In contrast, **Ondoku requires no installation!**
Since you can use it just by accessing the site in your browser, you can **start creating immediately** when you want audio.
Types of voices? Character nature and practicality are key
**Ondoku** and VOICEVOX also have differences in their voices.
VOICEVOX is characterized by its ability to use voices with strong character personalities, such as "Zundamon," "Shikoku Metan," and "Kasukabe Tsumugi."
Detailed intonation adjustments, known as voice tuning, are also possible.
In contrast, **Ondoku** offers a wide choice from **calm and trustworthy voices** suitable for narration and reading to **cute and friendly voices**.
Its greatest appeal is its high versatility, not depending on specific characters.
Among those looking for a VOICEVOX alternative, some may want to use character voices, while others may be looking for a free, high-quality reading tool.
If your goal is "it doesn't absolutely have to be Zundamon's voice" or "I want to easily create easy-to-understand commentary videos on my smartphone," **Ondoku is the best choice**!
[English/Foreign Languages] Create videos for foreign audiences with multilingual support!
Furthermore, **Ondoku** is equipped with **features that VOICEVOX does not have**!
That is the **multilingual reading function for English and other foreign languages.**
While VOICEVOX is an app specialized for Japanese, **Ondoku allows text-to-speech reading and downloading in languages from around the world, including English, French, Spanish, Chinese, and Korean.**
Even if you want to create videos or short videos for overseas audiences, you can easily create voice narrations using the same tool.

There are also unofficial apps and unofficial tools compatible with iPhone and Android smartphones
So far, we have introduced recommended VOICEVOX alternative tools and how to use them.
Besides those, there are unofficial alternative tools and unofficial apps that allow reading aloud in the voices of Zundamon, Shikoku Metan, and Kasukabe Tsumugi from iPhone (iOS) or Android smartphones.
Zunda Voice: Smartphone app for iPhone (with limitations)

Zunda Voice is a reading app used by installing it on an iPhone (there is no Android version).
It can be installed for free, but you can also pay for the paid version to use it even more conveniently.
While it is possible to read aloud with voices used in VOICEVOX such as Zundamon, being a smartphone app, it also has many limitations.
- Character limit: Up to 200 characters at a time for the free version, and up to 600 characters at a time for the paid version
- Free version requires using a "Gacha" function to increase the types of voices (all types unlocked in the paid version)
In this way, because it is a smartphone app for iPhone, its **functionality is limited** compared to the official VOICEVOX for PC.
Also, for commercial use, it is necessary to follow the terms of use for characters such as Zundamon, Shikoku Metan, and Kasukabe Tsumugi.
Web Version VOICEVOX: Reading aloud via VOICEVOX from a browser (with limitations)

Web Version VOICEVOX is a web app for browsers created unofficially by volunteers.
It is a tool that reads aloud by using VOICEVOX running on a computer prepared by an individual from a website, and the created audio can be downloaded.
It can be used as a substitute from an iPhone or Android smartphone browser.
However, **there are limits on reading long texts** required for video creation.
Also, there are **many difficult parts for advanced users in terms of usage**, such as the need to save a "Project Key" in the browser to save progress.
As a simple tool developed by an individual, there is also the disadvantage that it is unknown when it might become unusable.
Furthermore, when using it, it is necessary to follow the terms of use for the VOICEVOX software itself and for characters such as Zundamon, Shikoku Metan, and Kasukabe Tsumugi.
Apps and alternative tools for VOICEVOX have many limitations
In this way, alternative apps and software for using VOICEVOX on iPhone (iOS) or Android smartphones have functional limitations.
For conveniently reading text aloud with simple operations on an iPhone (iOS) or Android smartphone, the AI text-to-speech service Ondoku is recommended.
