When you are working on your language online you may be on zoom or another audio sharing tool that you can record
What can you do with the recording. It has some good examles, a few words you want to work on, some grammer you did not know before
There are tools for you to annotate your video/audio file but some are expensive or need a computer
So here are some simple ones:
1. if you have just an audio file – you may need to conver to video using some sites like https://www.onlineconverter.com/audio-to-video
2. Apps like Inshot allow you to add titles, emojis etc to a video on your phone for keeping.
3. Tools like Wavepad audio editor allows you to edit audio and insert say translations when you wnat, but does not provide any text to annotate audio
4. If you load your video to Youtube you can add cards – see example
a Select uploaded video in Studio
b. move down and select “cards” tab:
c. Add cards to places that interest you
