so,i saw a command in default command, but when i said it it doesn't took any action.
so i have an idea for this

this is called as (Speech to text). we can use a Speech to Text converter.
now we can create a saving speech text and command links to save speech in that.
converter name:we can use Speechnotes (or) Dragon Naturally Speaking
command for jarvis in shell :
command: jarvis,enable saving speech
response : opening Dragon Naturally Speaking {{d}}
Action : C:\program Files\ Dragon Naturally Speaking\dragon.exe\
now open Dragon Naturally Speaking options and search for speech saving location to C:\Users\DELL\AppData\Roaming\LINKS\Data save it as and rename it as test_saving speech
i hope this will work
if any errors please reply
