00:00 Summary. Well done! You’ve made it to the end of the course. In it, you’ve seen how to install the SpeechRecognition package and use its Recognizer class to easily recognize speech from both a file using .record() and microphone input using .listen().

00:18 You saw how to process segments of an audio file using the offset and duration keyword arguments of the .record() method. You’ve seen the effect noise can have on the accuracy of transcriptions, and have learned how to adjust a Recognizer instance’s sensitivity to ambient noise with .adjust_for_ambient_noise().

00:36 You’ve also learned which exceptions a Recognizer instance may throw—RequestError for bad API requests and UnknownValueError for unintelligible speech—and how to handle these with try/except blocks.

00:51 Speech recognition is a deep subject, but the foundations you’ve learned in this course will allow you to investigate further the areas that you’re interested in in this exciting topic. As ever, we hope you found this course useful and that we’ll see you again soon at realpython.com.
