The Fractal Fabric of Speech
نویسندگان
چکیده
An experiment was conducted in order to characterize the intrinsic fluctuations of human behavior as they are reflected in multiple repetitions of a single spoken word. Ten participants repeated the word “bucket” 1100 times, and fluctuations across repetitions in the acoustic measures of syllable duration, peak pitch, peak intensity and spectral intensity were analyzed for power law scaling relations. All measures for all subjects showed fluctuations resembling the scaling relation known as 1/f noise, with many distinct streams of 1/f noise running in parallel. These results provide evidence for the emergent basis of human behavior.

متن کاملFractal Characteristic-Based Endpoint Detection for Whispered Speech
In this paper, a fractal based approach is proposed to detect endpoints in whispered speech. The underlying principle is based on the fact that whispered speech is sufficiently chaotic and thus can be analyzed using fractal theory. Due to the different scope of fractal dimensions of silence, noise and speech segment, speech/non-speech segment could be determined from that with a simple decision...
