In the read aloud ebooks, the visual rendering of the text is accompanied by and synchronized to the rendering of audio files embedded in the ebook container. “Read aloud" assumes that the words in the audio file fit the written text. Two separate documents, ebook and audiobook, are assembled into a single electronic document - read aloud ebook.
The read aloud files can be developed in EPUB or PDF format. EPUB format presents a reflowable layout that exploits the capabilities of the modern e-reading devices to display the content on various screens. But EPUB can also present, like PDF, a fixed layout with pre-paginated content. Moreover, the latest version of EPUB (EPUB3), supports Media Overlays. This specification defines a profile of SMIL (Synchronized Multimedia Integration Language) grammar for synchronizing text rendering with audio playback. Advanced features such as synchronous highlighting of the text while reading and touch-to-play can be enabled as well.
The audio file can be created by recording human reading or using Text To Speech (TTS) specialized software apps. The best quality can be achieved by employing professional voice actors to narrate the text. This is usually an expensive solution and also not a very affordable one. As a convenient alternative, we use TTS software to generate natural sounding synthetic voices from the text.
You can choose between English, French, German, Spanish or Italian languages and for each of them, between male or female voice.
