Named entity recognition in spaCy
Named entities are real-world objects which have names, such as, cities, people, dates or times. We can use spaCy to find named entities in our transcribed text.
In this exercise, you'll transcribe call_4_channel_2.wav (file) using transcribe_audio() and then use spaCy's language model, en_core_web_sm to convert the transcribed text to a spaCy doc.
Transforming text to a spaCy doc allows us to leverage spaCy's built-in features for analyzing text, such as, .text for tokens (single words), .sents for sentences and .ents for named entities.

Have a go at this exercise by completing this sample code.
import spacy
# Transcribe call 4 channel 2
call_4_channel_2_text = transcribe_audio("call_4_channel_2.wav")
# Create a spaCy language model instance
nlp = spacy.load("en_core_web_sm")
# Create a spaCy doc with call 4 channel 2 text
doc = nlp(____)
# Check the type of doc
print(type(___))
