Techno-Speech, Inc. (located in Higashi-ku, Nagoya and led by Representative Director Keiichiro Oura) released the official version of its AI speech synthesis software "VoiSona Talk," which uses the latest AI technology to realistically reproduce human speech on March 22, 2024.

On September 1, 2023, we released a trial version of our speech synthesis software "VoiSona Talk" and have received a lot of feedback from our users, which has led to many improvements. After making various improvements, including the preset feature for speech styles and a user dictionary feature, we were able to release the official version on March 22, 2024. We are very grateful to our users for their feedback and warm encouraging comments so far.
New users can start using the software for free by registering an account at the official website below. Please download the latest version of the software and try it out. Existing users do not need to register again. "Tanaka San," a female voice library that is included as the default voice library and is characterized by her cute, slightly childish voice juxtaposed with a calm speaking tone, will continue to be available free of charge after the official release.

[About VoiSona Talk]
<Basic Editing Features>
You can synthesize voice simply by selecting the speaker in the track at the top of the window and entering text in the text field in the middle of the window. You can change any speech speed, volume, pitch, intonation strength, huskiness, and speech style in the editing UI on the right side of the window. In addition, on the editing UI at the bottom of the window, you can change readings, insert and delete pauses, change accents, and change phoneme lengths, etc., allowing you to create the nuances you want.

<Interpolation Feature for Speech Styles>
You can change the interpolation ratio of the speech style even in the middle of a sentence. It is possible to reproduce speech styles such as a gradual change from a sad voice to a happy voice.

<Preset Feature for Speech Styles>
There is the preset feature UI on the right side of the window that saves and restores preset values for speech speed, volume, pitch, speech style, etc., for each voice library. Favorite presets can be registered.

<User Dictionary Feature>
There is the UI on the right side of the window for the user dictionary feature, which registers user-specific proper nouns. By registering the readings and accents of proper nouns that occur frequently in your environment in advance, you can synthesize speech without having to edit the readings and accents each time.
