What kind of software is text-to-speech software?

First, let's briefly explain reading software and sites.

Features of text-to-speech software/sites

Features of reading software/sites

Text-to-speech software and sites are tools that load text and read it aloud as audio.

They read based on the input text and can save it as audio files such as MP3 or WAV.

Software for synthesizing speech has existed for a long time, but previously only software with robot-like voices existed, where it was immediately obvious that a computer had synthesized it.

However, it is different now.

Latest text-to-speech software and sites use AI to synthesize speech, allowing them to read text in clear and realistic voices, just like a professional narrator is speaking.

For reading text aloud, it is recommended to choose software or sites that use the latest AI.

Benefits of reading software/sites

Can read aloud immediately

Can read aloud immediately

Reading software and sites using the latest AI can read input text immediately.

For example, in the case of "Ondoku", it can generate 1,000 characters of reading audio in just a few seconds and save it as an MP3.

Easier and clearer than reading it yourself

It is very difficult for someone who is not a professional narrator or voice actor to read text aloud, and it usually results in articulation and pronunciation that is very hard to hear.

In such cases, by using a reading software or site, anyone can easily read aloud in a clear and easy-to-hear voice.

Furthermore, editing also takes a long time.

With text-to-speech software and sites using the latest AI, such effort is unnecessary.

Good cost performance

You can request a professional narrator or voice actor to do the reading, but it incurs a very high fee.

Furthermore, when requesting a professional, it takes time until the audio file, such as an MP3, is delivered.

In contrast, with reading software and sites, it is possible to read text for free and save the MP3 file immediately.

Dedicated software/sites are recommended for utilizing reading audio

Dedicated software/sites are recommended for utilizing reading audio

In fact, text-to-speech functions are standard on iPhone and Android smartphones.

By turning on the smartphone's reading function from the settings app, it is possible to read the content displayed on the screen.

However, if you want to utilize reading audio for hobbies or work, it is recommended to use dedicated reading software or sites.

The reason is that dedicated reading software and sites can save audio in formats such as MP3.

Since the reading functions standard on smartphones are for improving accessibility, they do not have an audio saving function.

With dedicated software and sites, you can save as audio files such as MP3, making it easy to import into video editing software or play as a broadcast on an audio player.

Since there are services like "Ondoku" that allow you to save MP3 files for free, dedicated software or sites are recommended for reading text.
