Second, I've been trying for a while to develop an application, using the google-tts https://github.com/horihiro/esp8266-google-tts library, that can download the embedded audios in the generated google translator links, but I don't have a sufficient level of knowledge to make this possible.
My intention is to create a talking clock (for my sister who is blind), and by pressing a button it tells her the time (wristwatch version) or by doing a clap (wall clock / alarm clock version).
Since I personally know other people who have this condition who speak other languages, it would be great to be able to automatically download the audios of the hours of other languages, instead of having to "do it manually"; I know that there are already devices that fulfill this task, but I would like to achieve this goal to give my sister a useful gift, and by the way, help other people.
My question is, how can I "download" the embedded audio in this link and save it to an SD?
English is not my mother tongue, sorry if I make mistakes.
