Microphones and Measurements
Gert Foget Hansen, Nicolai Pharao · 2009
This paper presents the current status of an ongoing investigation of differences in formant estimates of vowels that may come about solely due to the circumstances of the recording of the speech material. The impact of the interplay between type and placement of microphone and room acoustics are to be examined for adult males and females across a number of vowel qualities. Furthermore, two estimation methods will be compared (LPC vs. manual). We present the pilot experiment that initiated the project along with a brief discussion of some relevant articles. The pilot experiment as well as the available results from other related experiments seem to indicate that different recording circumstances could induce apparent formant differences of a magnitude comparable to differences reported in some investigations of sound change.
