T5. Natural Language and VR

Question 1

What is the purpose of Natural Language Processing?

Answer 1

NLP is concerned with the ability of a computer to understand human interaction in both spoken and written form, enabling machines to analyze, understand, and generate human speech, making interactions more ‘human-like’.

Question 2

What is Natural Language Processing used for?

Answer 2

1. Spam filtering: To identify and block unwanted emails by scanning text.
2. Answering search engine questions: Using key words.
3. Extracting key information: Evaluating stock market patterns for buy/sell/hold decisions.
4. Summarising information: Picking out key information.

Question 3

What is a Voice Recognition System?

Answer 3

A combination of hardware and software that decodes spoken commands to operate devices or execute commands without peripherals like keyboards or mice.

Question 4

How do Voice Recognition Systems work?

Answer 4

The first stage involves input and digitisation of spoken words into VR software, requiring a computer with a sound card and a microphone or headset.

Question 5

How can voice recognition be achieved?

Answer 5

1. Pattern matching:
2. Pattern and feature analysis: .
3. Statistical analysis:
4. Artificial neural networks

Question 6

Pattern matching:

Answer 6

Recognizes spoken words in their entirety, often used in automated switchboards

Question 7

Statistical Analysis

Answer 7

This applies the rules of grammar to help predict words to support speech recognition in instances when the spoken word was not entirely clear.

Question 8

ANN

Answer 8

This can be used to support voice recognition They can be trained using examples to recognise spoken input to improve the accuracy of voice recognition applications.
