May 24, 15:00，Researcher Xiong Ziyu, Director of the Phonetic Research Office of the Institute of Linguistics, Chinese Academy of Social Sciences, is a guest in the 376th issue of "New Xingtan"，Academic lecture entitled "Calculation and Application of Tone Value" in A606, Zhixin Building。The lecture is hosted by Associate Professor Liu Wen of our college，Professor Yue Lijing attended，Attracted dozens of teachers and students to listen。
The beginning of the lecture，Associate Professor Liu Wen gave a brief introduction to Researcher Xiong Ziyu’s research fields，Talk about researcher Xiong Ziyu’s experimental phonetics research、Very fruitful results have been achieved in speech corpus construction and speech data processing。In addition, Associate Professor Liu Wen mentioned，Researcher Xiong Ziyu developed a series of recordings、Tools for phonetic annotation and scripts for acoustic analysis and perception experiments，Bet365 gamesIt has brought great convenience to the investigation and analysis of dialects and ethnic languages in the academic community。
First，Researcher Xiong Ziyu’s early wave plan、Tone inference ruler、Electronic picture adjuster、Talking about Yutuyi，Introduced to the students various acoustic instruments used for experimental research on intonation since the beginning of Chinese experimental phonetics。Then researcher Xiong Ziyu pointed out，With the continuous upgrading of computers，Acoustic analysis software has gradually replaced some acoustic instruments with higher thresholds。PraatSpeech analysis software5231_5235Give voice acousticsofResearch brings great convenience，Its portability and its batch collection of acoustic data、Mark、The function of analysis is alsomoreSuitable for large-scale data processing.At the same time,Researcher Xiong Ziyu is based onPraatThe program explains the collection (using a self-developed voice corpus recording toolxRecorder.exe）、Automatic labeling、Three aspects of automatic extraction and verification of pitch data，And take the analysis of dialect tone system as an example，Summary of the experimental process and related basic data。
After，Researcher Xiong bet365 online sports betting liveZiyu gave a detailed explanation on the method of measuring intonation value，And demonstrated the application examples of tone value calculation in the analysis of tone systems of various dialect points。In the study of dialect single tone system，Researcher Xiong Ziyu takes Chongqing Hechuan dialect and Shandong Gaomi dialect as examples，Shows the histogram of the tone value distribution data of each tone type example and the tone pitch data graph produced by the script program，Intuitive using diagrams、Quickly captures information on whether ancient tunes are differentiated，Successfully investigated the evolution of ancient and modern tones in this dialect。Research on continuous reading tone changes，Researcher Xiong Ziyu used materials in Tianjin dialect to show the students the specific process of data processing，Including self-developedofxSegmenterWorkerTools for cutting and labeling voice materials,UsePraatScriptProgram to extract data, etc.，Later, through the analysis of the distinguishing coefficients between each tone class，To draw a picture、The list shows the conditions for the occurrence of continuous tone changes。
final，Researcher Xiong Ziyu is based in Beijing、Guangzhou、Experimental materials from dialect points such as Xiamen bet365 online sports betting liveas examples，Introduced an example of applying the aforementioned intonation value calculation method to the evaluation of learners' tone system。Learner’s intonation system evaluation is measured by four indicators，After measuring the intonation value of each speaker，On this basis, the independence coefficient of each adjustment class、Stability coefficient、Calculate the correctness coefficient and the discrimination coefficient between the two classifications，Use this as the "score" of the learner's intonation system。These coefficients reflect the learner’s tone type and its distribution information from different angles，Be able to better describe the learner’s tone acquisition on a unified scale，Thus achieving cross-speaker、Comparison across dialect points。
Associate Professor Liu Wen expressed his gratitude to Researcher Xiong Ziyu for his wonderful speech on behalf of teachers and students，And summarized the content of this lecture。Associate Professor Liu Wen pointed out，Researcher Xiong Ziyu showed many details of data processing during the lecture，In addition, he also presented an experimental phonetics research oriented to linguistics based on the perspective of acoustics。A good phonetics study is not limited to Bet365 gamesthe completion of experimental procedures，But there is a specific research goal，Solve a specific linguistic problem，This is worth learning and thinking by students。
During the question session, Researcher Xiong Ziyu JiYuPraatSpeech analysis software performanceshows the specific operation process of tone value calculation。At the same time，On-site teachers and students discussed the application of tone value calculation in the study of the evolution of ancient and modern dialect tones、Recording and annotation of dialect survey materials、Asked researcher Xiong Ziyu about the explanation of learners’ tone system evaluation indicators and other issues，Researcher Xiong Ziyu patiently and carefully answered these questions，The communication atmosphere is very active，The lecture ended successfully with warm applause。
