Q & A

Here are some common questions the users have asked me more than once, with my answers. If you have any other questions, suggestions or you want to report a bug please don't hesitate to contact me.

Why can't I hear the sound in my browser when I play lesson's audio?

Some browsers (Chrome, Firefox, Edge, Opera...) on some platforms (Windows, Linux, macOS, Android,...) will be able to play sound, while other browsers on other systems won't. For example, Opera on Android doesn't support the functionality needed to play sound from text. The Chrome browser, on the other hand, worked pretty well for me on Windows and Android.

A bit more technical explanation:
The technology used to generate sound from text on this website is called Web Speech API. The Web Speech API was introduced in 2012 by the W3C community, but until now it has not been standardized, and it seems like every browser manufacturer on every different platform has its own way of implementing this specification. There are commercial options for converting text-to-speech, but since this is a free site, my only option was to implement text-to-speech functionality with the Web Speech API.

Some tips:
To be able to reproduce the sound from text, the browser needs voices. On Windows I suggest you install the German language pack. This doesn't mean that the UI for Windows will be in German, you will just get the opportunity to change the keyboard to a German one, and you will get German voices.
Chrome browser can use Windows voices for German, but it also has its own web voices that worked for me well on Windows and Android.
On other systems (device, operating system, browser), please check for yourself to see what is available.

Why can't I hear the sound for the language course?

Language course has prepared audio files, and you should be able to hear the sound. Every modern Internet browser should be able to play sound, so please update your browser. You can also check if your device has sound muted.

When I open a lesson, it takes a long time to load the page content?

Your machine (computer, smartphone, or tablet) paginates the content of the lesson to make it more user-friendly. If you have a slow machine, this might take some time. In that case you can turn off pagination in your user's page. If pagination is turned off, the entire content of your lesson will be displayed immediately, and page loading for a lesson will work much faster.
