I found a problem with streaming decoding, and all above codes have this problem.
The currently sent data will not be transcribed until 3 seconds later, so the last 3 seconds of text will be lost in the transcribed text of a file. If another 3 seconds of data are sent in, they will not be transcribed. Is there any way to solve this problem? Or let this data be solved immediately without delay? Thanks.
