I need to know how many minute I have used.
I can't find it anywhere in the dashboard.
(By the way, Google Speech to Text API have 60 minute/month free trial)
Update: @mk_sta's answer seem like correct:
But after more testing, (upload a 55 seconds audio and check if 393+55=448)
It doesn't work. the number still is 393("7 Day Peak Usage")
But "Current Usage" did change to 55. which is correct, but the left showed "Audio second per day", I don't need "per day"
