Measuring the Accuracy of Historic Phonetic Instruments
نویسندگان
چکیده
The fundamental experimental findings on speech and musical sounds date back to the pre-electronic era. It is interesting to estimate the accuracy of the mechanical measurement tools which have been used in that time. For this purpose, the authors performed measurements at historic acoustic resonators and at some prototypes of MAREY’s capsules. The results are summarized in this paper.

Measuring Pitch with Historic Phonetic Devices
Measuring pitch is one of the most important but also most difficult tasks in experimental phonetics. It is interesting to study how the difficulties have been solved in the times before the computer was introduced in the phonetic laboratories. In this paper, this is discussed using a number of exhibits of the acoustic-phonetic collection of the Dresden University. There will be a small exhibit...
متن کاملAcoustic Experiments with Wethlo’s Larynx Model
Historic phonetic instruments are useful objects to support the education in speech science. In this paper, we describe the reactivation of mechanical models which served in the past for developing the theories of speech production. At first, larynx models from Wethlo (the cushion pipes) are investigated in practical experiments. We describe the materials and pressure conditions which we found ...
متن کاملHow to Gauge Accuracy of Measurements and of Expert Estimates: Beyond Normal Distributions
To properly process data, we need to know the accuracy of different data points, i.e., accuracy of different measurement results and expert estimates. Often, this accuracy is not given. For such situations, we describe how this accuracy can be estimated based on the available data. 1 Formulation of the Problem Need to gauge accuracy. To properly process data, it is important to know the accurac...
متن کاملHow did it work? historic phonetic devices explained by coeval photographs
The early history in experimental phonetics and speech technology is featured by numerous sophisticated devices which we can study today in a number of historic collections which are located mainly at universities. In many cases, however, it is not easy to understand how these devices have been applied in an optimal way. Illustrations and historic photographs are especially helpful. The histori...
متن کاملEstimation of Daily Evaporation Using of Artificial Neural Networks (Case Study; Borujerd Meteorological Station)
Evaporation is one of the most important components of hydrologic cycle.Accurate estimation of this parameter is used for studies such as water balance,irrigation system design, and water resource management. In order to estimate theevaporation, direct measurement methods or physical and empirical models can beused. Using direct methods require installing meteorological stations andinstruments ...
