Pitch Determination of Speech Signals

Více o knize

The book delves into the complexities of pitch measurement in acoustic speech signals, emphasizing its crucial role in conveying prosodic information. It highlights the ear's heightened sensitivity to changes in fundamental frequency compared to other parameters. Despite the seemingly straightforward task of detecting pitch, challenges arise from speech's nonstationary nature, the variability of human vocal tracts, and the wide range of fundamental frequency across different speakers. These factors contribute to the difficulty of accurately determining pitch in speech analysis.
