Exercise

From AudioFile to AudioData

As you saw earlier, there are some transformation steps we have to take to make our audio data useful. The same goes for SpeechRecognition.

In this exercise, we'll import the clean_support_call.wav audio file and get it ready to be recognized.

We first read our audio file using the AudioFile class. But the recognize_google() method requires an input of type AudioData.

To convert our AudioFile to AudioData, we'll use the Recognizer class's method record() along with a context manager. The record() method takes an AudioFile as input and converts it to AudioData, ready to be used with recognize_google().

SpeechRecognition has already been imported as sr.

Instructions
