Pragmatic vs 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”).
Compare pragmatic versus phonetic analysis.
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 |
