This is a must-have application for video text-to-speech, sub-speech creation, and multi-language support.
If you load an "SRT" file, which is a format for video subtitles, you can play the audio at the time the subtitles are displayed.
By attaching the audio file created by this application to the video using video editing software, you can play the synthesized audio in the video.
By applying this, it is possible to convert audio from YouTube, etc. into multilingual audio.
Please use an external free service for the acquisition of the video, acquisition of the subtitle file, and translation of the subtitle file.
The audio can be saved as "WAV" files with common extensions, and can also be converted to mp3 files.
