Sinkronigo
Multimedia digital publishing technology


What we do

We create electronic books enhanced with human narrations, in which text is highlighted as it is spoken. Although read aloud electronic books have been defined in the latest epub standard since 2011, producing electronic books with an accompanying narration, manually aligned with the text, is very time consuming and not cost-effective when large volumes of text (like novels and essays) are at stake. By using the latest speech and text processing technology we can automatically and accurately align text and audio at word, sentence or paragraph-level. The resulting electronic books are fully compatible with both iTunes and Google Play stores.


Who we are

Founded by people with a large experience in research in the areas of speech and text processing, Sinkronigo was born from their passion for digital publishing and their experience as avid eBook readers. Sinkronigo emerged from the realization of how tiring it is to listen to long text documents narrated by artificial voices generated by text-to-speech systems, and the non-existence of fully automatic end-to-end solutions to combine existing human narrations with text.


What does Sinkronigo mean

Sinkronigo means synchronization in Esperanto. It represents well what we do and mirrors the fact that our technology is language independent.
