However, software that you install and use on a PC is very troublesome to set up.
PC specs are also necessary to use AI reading comfortably.
In that regard, text-to-speech sites that can be used online can be used easily without installation!
Of course, downloading is also possible!
We will also introduce text-to-speech sites that can be used for free, so why not use this article as a reference to have AI read your text?

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 out entered sentences (text) as an audio file.
Services that read text as audio have existed for a long time, but with the spread of AI, more services have appeared than ever 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, it is necessary to note that service content varies greatly from site to site for text-to-speech sites.
Advantages of text-to-speech sites
Text-to-speech sites have several advantages compared to reading software that you install on a PC.
1. No installation required and ready to use immediately
The biggest advantage of a text-to-speech site is that there is no need to install anything.
Text-to-speech software that you install on a PC takes time and effort to install and perform initial settings.
In that respect, with a text-to-speech site, no software installation work is required at all.
You can open the website when you want to use it and read text aloud immediately.
2. Slow connection speeds are OK
The fact that no large downloads are 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, downloading before installation can take time.
In particular, because the latest AI reading software has a large AI voice synthesis engine capacity, it is normal for the download size to be 1GB or more.
In contrast, text-to-speech sites can be used without problems even if the connection speed is not fast.
The download size of the audio file is much smaller than the capacity of AI reading software, so it is possible to download 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 the 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 instead, high PC specs are required if you install and use it.
With text-to-speech sites used from a browser, the actual processing is performed by high-performance computers (servers) at the other end of 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, text-to-speech sites used from a browser are recommended over reading software that you install and use.
Things to keep in mind when choosing a text-to-speech site
There are things to keep in mind when choosing a text-to-speech site.
That is,
- Whether files can be downloaded even when using it for free
This is the point.
Among text-to-speech sites, there are services like 『Ondoku』 that can be used for free.
However, depending on the service:
- You can read aloud for free and listen on the website
- Downloading is paid
There are such cases.
If you are choosing a text-to-speech site from now on, it is recommended to check in advance whether files can be downloaded even when using it for free.
