Please someone help me with this below code:

Transcribe the audio using Whisper API

openai.api_key = "My API Key"
audio_file = open("output.wav", 'rb')
transcript = openai.Audio.transcribe("whisper-1", audio_file)

Save the transcript results in a variable

transcription = transcript

I'm trying transcribe a record and don't be working. The library that i'm using is "openai".

And when i used the "os" with "os.getenv" ahead of my API key happened this error : openai.error.AuthenticationError: No API key provided.
