Frication and Voicing Classification
نویسندگان
چکیده
Phonetic detail of voiced and unvoiced fricatives was examined using speech analysis tools. Outputs of eight f0 trackers were combined to give reliable voicing and f0 values. Log energy andMel frequency cepstral features were used to train a Gaussian classifier that objectively labeled speech frames for frication. Duration statistics were derived from the voicing and frication labels for distinguishing between unvoiced and voiced fricatives in British English and European Portuguese.

Amplitude modulation of frication noise by voicing saturates
The two distinct sound sources comprising voiced frication, voicing and frication, interact. One effect is that the periodic source at the glottis modulates the amplitude of the frication source originating in the vocal tract above the constriction. Voicing strength and modulation depth for frication noise were measured for sustained English voiced fricatives using high-pass filtering, spectral...

The present study investigates the extent of word-final devoicing in Russian for three groups of speakers: monolingual native Russian speakers (4 Ss), native Russian speakers with knowledge of English (7 Ss), and American English learners of Russian (9 Ss). Thirty-four minimal pairs of Russian words differing in the underlying voicing of word-final obstruents were recorded. Acoustic analysis fo...
متن کاملVoice onset time and fundamental frequency as cues to the /zi/-/si/ distinction
The present series of experiments used factorial designs to evaluate which acoustic features are primarily responsible for the voicing distinction in the syllables Izil and Isi/. Increases in frication duration tend to make the syllable more voiceless only if vocal cord vibration is absent or at a very low level during the frication period. Increasing the period between the onset of frication a...
متن کاملDuration of frication noise required for identification of English fricatives.
Natural speech consonant-vowel (CV) syllables [( f, s, theta, s, v, z, ŏ] followed by [i, u, a]) were computer edited to include 20-70 ms of their frication noise in 10-ms steps as measured from their onset, as well as the entire frication noise. These stimuli, and the entire syllables, were presented to 12 subjects for consonant identification. Results show that the listener does not require t...
