Of course, downloading is also possible!
We will also introduce text-to-speech sites that can be used for free, so why not try reading text with AI using this article as a reference?

How to use downloadable text-to-speech sites?
We will explain the features of text-to-speech sites and points you should check before using them.
What is a text-to-speech site?

A text-to-speech site is a site that reads the entered text aloud as an audio file.
Services that read text as audio have existed for a long time, but with the spread of AI, many more services have appeared compared to before.
Text-to-speech sites using the latest AI can generate realistic and easy-to-hear audio files that sound like a real human is speaking.
However, please note that the service content of text-to-speech sites varies greatly from site to site.
Advantages of text-to-speech sites
Text-to-speech sites have several advantages compared to text-to-speech software that you install and use on a PC.
1. No installation required and can be used immediately

The biggest advantage of text-to-speech sites is that there is no need to install them.
Text-to-speech software installed on a PC takes time and effort to install and perform initial settings.
In contrast, with a text-to-speech site, no software installation work is required at all.
You can open the website whenever you want to use it and immediately read the text aloud.
2. Slow internet speed is OK

The fact that no software download is required is also a convenient point of text-to-speech sites.
Software that requires installation has a large download capacity, and depending on the connection status, the download before installation can take a long time.
In particular, because the AI voice synthesis engine capacity of the latest AI text-to-speech software is large, it is common for the download size to be over 1GB.
On the other hand, text-to-speech sites can be used without problems even if the connection speed is not fast.
Since the download size of audio files is much smaller than the capacity of AI text-to-speech software, downloading is possible without problems even if you are concerned about connection speed.

However, depending on the text-to-speech site, the capacity of the top page itself may be large, and loading may take time.
In such cases, it is recommended to try other services like 『Ondoku』 where page loading is lightweight.
3. No impact from PC specs

Text-to-speech sites can be used comfortably without being affected by PC specs.
Text-to-speech using AI is very high-performance, but in exchange, high PC specs are required when installing and using it.
With text-to-speech sites used from a browser, the actual processing is performed by a high-performance computer (server) on the internet, so you can comfortably read text with AI regardless of the specs of the PC at hand.
- The specs of the PC provided by the company are low
- Using an old PC
In such cases, a text-to-speech site used from a browser is recommended rather than text-to-speech software that requires installation.
Points to consider when choosing a text-to-speech site

There are things you should be careful about when choosing a text-to-speech site.
That is,
- Whether you can download files even when using it for free
Text-to-speech sites include services that can be used for free, such as 『Ondoku』.

However, depending on the service:
- You can read text for free and listen on the website
- Downloading is paid
There are such cases.
If you are choosing a text-to-speech site, it is recommended to check in advance whether you can download files even when using it for free.
