Periodicity extraction for voiced sounds with multiple periodicity
A periodicity extraction method is introduced to analyze voiced sounds with a complex excitation behavior. Although general voiced sound has only one periodicity, some voiced sounds such as the pathological voice and the singing voice often have multiple periodicities. A method for estimating multiple periodicities from voiced sounds to deal with these kinds of voices is proposed in this articl...
متن کاملA measure of aperiodicity and periodicity in speech
In this paper, we discuss a direct measure for aperiodic energy and periodic energy in speech signals. Most measures for aperiodicity have been indirect, such as zero crossing rate, highfrequency energy and the ratio of high-frequency energy to lowfrequency energy. Such indirect measurements will usually fail in situations where there is both strong periodic and aperiodic energy in the speech s...
متن کاملEpoch Extraction of Voiced Speech
A general theory of epoch extraction of overlapping nonidentical waveforms is presented. The theory is applied to outputs of models of voiced speech production mechanism and to actual speech data. Some typical glottal waveshapes are considered to explain their effect on the speech output. It is shown that the points of excitation of the vocal tract can be precisely identified for continuous spe...
متن کاملMonaural Voiced Speech Separation with Multipitch Tracking
Separating voiced speech from its mixtures with interferences in monaural condition is not only an important but also challenging task. As multipitch tracking can enable much better performance of speech separation for CASA systems, we propose a new multipitch determination algorithm, which can be used under various kinds of noise conditions. In the process of multipitch estimation, a new repre...
متن کاملReverberation impairs brainstem temporal representations of voiced vowel sounds: challenging “periodicity-tagged” segregation of competing speech in rooms
The auditory system typically processes information from concurrently active sound sources (e.g., two voices speaking at once), in the presence of multiple delayed, attenuated and distorted sound-wave reflections (reverberation). Brainstem circuits help segregate these complex acoustic mixtures into "auditory objects." Psychophysical studies demonstrate a strong interaction between reverberatio...
