This software product will automatically convert user specified text information into audio information, and can automatically merge audio data into video files, so as to generate MP3 audio files and MP4 video files. The software product uses the TTS function provided by the operating system to convert Chinese text to speech. The TTS engine can be installed in the operating system. Two TTS engines, WinRT and sapi, are provided by default in Windows 10. The WinRT engine is more powerful and supports more roles. You can install the required TTS language package on the operating system. After the TTS language is successfully installed, it will be displayed on this interface. Common languages are Chinese, English, Japanese, Russian and so on. The TTS language determines not only the language used for text-to-speech, but also the language used to output the relevant information in the video screen, and the language used to output the relevant information in the generated PDF and HTML documents. Users can specify multiple language types of text files for the same image screen, and the software will automatically select the corresponding text files according to the TTS language when it is actually generated. TTS roles are used to select a particular voice model, such as male and female voices. There are TTS engines that offer multiple speech models for the same gender. Audio recording device Specifies which device to use for recording. The software will record the voice message while playing it using TTS. The user should choose a stereo mixing device as the recording device, so that the final video will contain only the sound played on the local computer, and not the sound recorded to the external environment.
