ITPEC FE Morning April 2021 Question 63
ITPEC FE Morning April 2021 — Question 63 of 80
A chatbot is software that uses natural language processing (NLP) techniques and is employed for applications to communicate with a human — conducting interactive, two-way dialogue in text or voice.
Why not others:
- (a) Describes image recognition/captioning software (image processing → describe image details), not a chatbot.
- (c) Describes speech-to-text (voice recognition) software — converts voice into text, no interactive dialogue.
- (d) Describes automatic subtitle generation — also speech processing, but the purpose is one-way (generating subtitles for video), not conversational interaction.
Key rule: A chatbot = NLP + two-way communication with a human. If the description mentions image, signal, or speech processing without interactive dialogue, it's not a chatbot.
