Exercise

Transcribing audio with one line

Alright, now you've got functions to convert audio files and find out their attributes, it's time to build one to transcribe them.

In this exercise, you'll build transcribe_audio() which takes a filename as input, imports the filename using speech_recognition's AudioFile class and then transcribes it using recognize_google().

You've seen these functions before but now we'll put them together so they're accessible in a function.

To test it out, we'll transcribe Acme's first call, "call_1.wav".

speech_recognition has been imported as sr.
