1, phonological history: studying the changes of phonology in the long river of history. By analyzing ancient documents and modern dialects, phonologists can trace the evolution of pronunciation and reveal the laws and reasons of phonetic changes.
2. Phonology: study the composition and characteristics of phonetic system. Phonology pays attention to the relationship between different sounds and their distribution and application in a specific language or dialect, and explores the classification, combination and phonetic change of sounds.
3. Dialectics: Study the phonetic features of dialects in different regions. Through the investigation and comparison of dialects, phonologists can understand the phonetic differences and * * * between dialects and reveal the regional and social factors of phonetic changes.
4. Experimental phonetics: using modern experimental means to study the physiological, physical and psychological processes of speech. Experimental phonetics can make an empirical study on the generation, spread and perception of speech, and provide scientific basis and methodological support for phonology.
5. The relationship between phonology and literature: study the relationship between phonology and literature. By analyzing the prosody phenomenon in literary works, phonologists can reveal the role and influence of pronunciation in literary creation and provide new perspectives and methods for literary research.
Phonology research methods;
1, research method of historical documents: through in-depth study of ancient documents, we can understand the evolution process and laws of pronunciation. Through the comparative analysis of documents in different historical periods, we can reveal the changes of pronunciation in the long history.
2. Comparative method: Compare the phonetic features of different regions and languages, and understand their differences and * * * relationships. By comparing the phonetic features of different dialects, we can reveal the regional and social factors of phonetic changes.
3. Investigation method: Through field investigation and sampling, we can understand the pronunciation characteristics of people from different regions and social backgrounds. By investigating and comparing the pronunciations of people from different regions, ages and genders, we can reveal the social and individual differences of pronunciations.
4. Experimental method: The modern experimental method is used to make an empirical study on pronunciation. Through the phonetic experiment, we can reveal the physiological, physical and psychological process of pronunciation, and understand the pronunciation mechanism and phonetic perception law.
5. Induction: Through the statistics and analysis of a large number of data, the general rules and characteristics of pronunciation are summarized. By summarizing and classifying the phonetic systems of different languages, we can reveal the systematicness and regularity of pronunciation.
6. Mathematical analysis: using mathematics and computer science to process and analyze voice data. Mathematical analysis can accurately describe the acoustic characteristics and pronunciation process of speech and provide technical support for speech research and application.
