2. VOICEVOX

VOICEVOX , a text-to-speech and speech synthesis software, is one of the most popular software for converting text into speech.

This is software that you install and use , and is compatible with both Windows and Mac.

A special feature of this app is that there is a character for each type of voice .

Have you seen any of these characters on the internet, such as "Zundamon," an anthropomorphized version of Zunda mochi, or Kasukabe Tsumugi, a high school girl from Saitama?

Benefits of VOICEVOX

Intonation can be edited

The VOICEVOX software has an intonation editing function.

If you want to hear text speak more realistically, you can fine-tune the voice.

You can also specify the speed and intonation of the audio in detail.

You can interact with multiple characters

It is also possible to convert text into audio using multiple characters at the same time.

Free to use

VOICEVOX can convert text into speech for free.

Commercial use is also possible .

Disadvantages of VOICEVOX

It may be difficult to use for business purposes due to its strong character.

The biggest disadvantage of VOICEVOX is that the voice has a very strong character.

When audio includes characters, depending on the purpose of converting text to audio, the characters may be too strong and difficult to use .

When using it to convert text to audio for work, it is recommended to choose characters that are not often used on video sites such as YouTube.

Each character has different terms of use

In addition to the terms of use for VOICEVOX itself, there are also terms of use for each character .

It's a bit of a hassle to have to look it up for each character every time.

Please note that if you use the images for commercial purposes without crediting the copyright holder, a usage fee may be charged .

(For example, Zundamon, Shikoku Metal, Kyushu Sora, and Chugoku Usagi sound sources cost 400,000 yen + consumption tax for each character.)

Large download size

The download size is large, and depending on your environment, it may take a long time to install .

This is because all voices (tones of voice) are installed during installation.

The initial installation requires downloading over 1GB of files , so if you do not have a fast Internet connection or are using wireless rather than fiber optic, the installation will take a considerable amount of time.

Usability depends on PC specs

Since VOICEVOX is software that must be installed on a PC, the speed of voice synthesis depends on the PC specifications.

To use the "GPU mode" comfortably, you will need a high-spec PC equipped with a GPU (graphics board).

Foreign languages not supported

Since VOICEVOX was developed for the Japanese language, it can only convert Japanese text into audio.

3. COEIROINK

COEIEOINK is a text-to- speech software designed primarily for use in creative writing .

This is software that you install and use , and is compatible with both Windows and Mac.

Credit is required when using.

Benefits of COEIROINK

Charming characters

The official and authorized characters are very attractive and of high quality in both audio and illustrations.

Commercial use allowed

COEIROINK is available for commercial use .

However, credit is required for both commercial and non-commercial use.

Comprehensive editing features

Although it takes some time, it also has comprehensive editing functions for accents and intonation.

You can create your own original voice synthesis

COEIROINK has a function that allows you to create and publish original synthetic voices called "MYCOE."

It is also possible to create audio material based on your own voice.

Disadvantages of COEIROINK

The characters are very impressive

Like VOICEVOX, the downside is that the characters are very memorable .

If you are trying to convert text to audio for work or business purposes, you may find it difficult to use.

The terms of use are a bit complicated

Please note that the scope of use for each character is determined separately from the terms of use for COEIROINK itself.

Voices created by users other than official or certified characters may also have their own terms of use.

Conversely, depending on the character, uses that are prohibited by other voice synthesis services and software, such as "use in adult content," may be permitted.

Large download size

Like VOICEVOX, COEIROINK also has a large download size .

The first time you install it, you will need to download a file of about 2GB , which may take some time depending on your internet connection.

Installation is time-consuming

Installing COEIROINK requires some knowledge about PCs .

You will need to download multiple files, unzip them, and place them in a folder.

Usability depends on PC specs

Like VOICEVOX, COEIROINK is software that needs to be installed and used, so ease of use depends on the specifications of your PC.

For comfortable use, we recommend a high-performance PC equipped with a GPU (graphics board).

4. Boyomi-chan

Boyomichan is a text-to-speech software compatible with Windows .

This software uses the long-existing synthetic voice library "AquesTalk," and can read text in a unique, though not realistic, voice.

Benefits of using Boyomi-chan

Very light operation

Since it is an old software, it is very lightweight .

You can convert text to audio without any problems even on a PC with low specifications.

Small download size

The file size is also very small, only about 1.5MB , so it can be downloaded quickly.

Easy to use

The operation screen is very simple.

At the same time, it still has the minimum adjustment functions such as speed and pitch.

Commercial use allowed

Boyomi-chan uses the older version of "AquesTalk," which can be used free of charge for both commercial and non-commercial purposes, so it can also be used for commercial purposes .

Extensive collaboration features

It has a wide range of functions that allow it to link with other software to read out displayed content, such as the ability to read out the clipboard (copied text) and the ability to read out Twitter posts.

Advanced usage such as reading content from other software is also possible.

Disadvantages of Boyomi-chan

Lack of realism

Since Boyomichan is an older generation synthetic voice software, it lacks realism.

All of the voices you can choose from are old-fashioned synthetic voices .

It is used in a distinctive way in videos on the Internet, including so-called "yukkuri videos," so if you are not careful about the situations in which you use it, it can sound awkward.

5. AIVOICE

AIVOICE is a voice synthesis software developed by AI Corporation.

We use the speech synthesis engine "AITalk" .

Software to succeed VOICEROID and VOICEROID+, for which support has ended, is also available as AIVOICE.

Disadvantages of AIVOICE

Expensive for personal use

It has many features and high performance, but it is also quite expensive for personal use .

May be difficult to use for business purposes

AIVOICE, which is aimed at personal users, comes with many attractive characters, but for business use, the strength of the characters can sometimes be a negative.

The speech synthesis engine used, "AITalk," is very high-performance, so if you want to use it for business purposes, we recommend using AITalk for businesses, which will be introduced next .

6. AI Talk

Speech synthesis software using the speech synthesis engine "AITalk" is also sold as a product for corporate use.

It is perfectly suited to business situations where you need to convert text to audio, making it ideal for business use.

Disadvantages of AITalk

The price is high

For example, the basic fee for the narration creation software "AITalk Voice Craftsman" is 50,000 yen per month (excluding consumption tax).
