[NEW EXAMPLE REQUEST] Translating with Asynchronous call

[chxrrysy]

Hello! I'm a developer developing a transcribe with php. If you look at the example of Amazon, there is a time delay due to the sleep (5) part, and I want to eliminate this phenomenon. I know that startTranscriptionJob is an asynchronous call, but is there a way to do it quickly without the sleep (5) part? I'm sending you an apology for my immature English. Please reply. Thank you.
