Crash Course Computer Science: Natural Language Processing Quiz

What is the main difference between machine languages and natural languages?

• Machine languages have large vocabularies.

• Natural languages are used only in programming.

• Machine languages require 100% accuracy in spelling and syntax.

• Natural languages follow highly structured conventions.

What is the primary goal of Natural Language Processing (NLP)?

• To improve computer vision capabilities.

• To create new programming languages.

• To enable computers to understand and generate human language.

• To develop new hardware for computers.

What are 'parts of speech' in the context of NLP?

• Different programming languages.

• Algorithms for speech recognition.

• Types of words in a language like nouns, verbs, and adjectives.

• Rules for constructing sentences.

What is a 'parse tree' used for in NLP?

• To store all possible sentences in a language.

• To tag words with parts of speech and show sentence structure.

• To translate languages.

• To generate new words.

How do modern chatbots differ from early rule-based chatbots?

• They use hand-crafted rules.

• They are based on machine learning and large datasets.

• They can only handle simple tasks.

• They do not require any training data.

What was the first speech recognition system developed by Bell Labs called?

• ELIZA

• Harpy

• Audrey

What is the main advantage of using deep neural networks in speech recognition?

• They require no training data.

• They can recognize an unlimited number of words.

• They provide the best accuracy.

• They are based on hand-crafted rules.

What is a spectrogram used for in speech recognition?

• To convert text into speech.

• To visualize the amplitude of sound waves over time.

• To plot the magnitude of different frequencies over time.

• To store phonetic components of words.

What is the main challenge in speech synthesis?

• Creating natural-sounding speech from text.

• Translating languages.

• Generating text from speech.

• Recognizing spoken words.

What is the expected future trend for voice user interfaces?

• They will become less common.

• They will be used only in specialized applications.

• They will become as common as screens and keyboards.

• They will be replaced by new physical input devices.
