## Question

Compare pragmatic versus phonetic analysis.

## Short answer

Pragmatic analysis is the highest NLP level, using context and world knowledge to find intended meaning (e.g., interpreting “Can you pass the salt?” as a request). Phonetic analysis is the lowest, dealing with speech sounds, pronunciation, and converting speech signals into phonemes or words (e.g., recognising “ba-nk” as “bank”).

## Answer

**Pragmatic analysis** is the highest level of NLP analysis; it interprets a sentence in the context of the situation, speaker, listener and world knowledge to find the intended meaning. **Phonetic (phonological) analysis** is the lowest level; it deals with speech sounds and how they are produced and combined into words.

| Point | Phonetic analysis | Pragmatic analysis |
|---|---|---|
| Level | Lowest (sound level) | Highest (use/context level) |
| Concerned with | Speech sounds (phonemes), pronunciation, intonation | Intended meaning, speaker intention, context |
| Input | Speech signal | Sentence plus situation and previous discourse |
| Used in | Speech recognition and synthesis only | Text and speech understanding |
| Knowledge needed | Sound rules, acoustics, phoneme inventory | World knowledge, speaker goals, discourse context |
| Output | Sequence of phonemes/words | Real intended meaning or action |
| Example | Recognising "ba-nk" as the word "bank" from sound | "Can you pass the salt?" understood as a request, not a question about ability |
| Difficulty | Accent, noise, homophones | Sarcasm, indirect speech, reference |

## Check yourself

The answer's key points as multiple-choice questions, with the correct option and why.

1. Which statement about the levels is correct?
   A. Phonetic analysis is the highest level and pragmatic the lowest
   B. Both are the same level
   C. Phonetic analysis is the lowest (sound) level and pragmatic the highest (context) level
   D. Both apply only to written text
   Answer: C. Phonetic analysis deals with sounds at the lowest level, while pragmatic analysis finds intended meaning in context at the highest level. (Key point: Level of analysis)

2. Which analysis is used only for spoken input (speech recognition and synthesis)?
   A. Pragmatic analysis
   B. Phonetic analysis
   C. Both equally
   D. Neither
   Answer: B. Phonetic analysis works on the speech signal, whereas pragmatic analysis applies to both text and speech. (Key point: Input and use)

3. What knowledge does pragmatic analysis need compared with phonetic analysis?
   A. Phoneme inventory and acoustics
   B. Only a dictionary
   C. Only grammar rules
   D. World knowledge, speaker goals and discourse context
   Answer: D. Pragmatics needs context and world knowledge, while phonetics needs sound rules, acoustics and phonemes. (Key point: Knowledge needed)
