TL;DR: Kindergarten and second-grade children's perception of voicing distinctions among the stop consonants was investigated by assessing their ability to identify and discriminate a series of synthetic speech stimuli varying in voice onset time, suggesting that the differential discriminability of stimuli along the VOT continuum has a biological basis.

TL;DR: The results of the experiment indicate that the present procedure is feasible for studying the intelligibility of syllables and their constituent phonemes, and that the voicing manner of release, and place of articulation of the consonant remain evident when the syllable is truncated at the initial end to commence 50 msec before the peak intensity of the vowel of the syllables.
Abstract: This study was undertaken to determine the effect upon perception of deleting different numbers of 10 msec segments from the initial part of each of a set of consonant‐vowel syllables. The scores that were analyzed were proportions of correct identifications of the residual elements by panels of listeners. The outcome was expressed in terms of correct identifications at each duration of the stimuli. Both the correct and error responses were studied to determine the relationship of voicing, manner of release (plosiveness and fricativeness) and place of articulation, to the identification of the stimuli. The results of the experiment indicate that the present procedure is feasible for studying the intelligibility of syllables and their constituent phonemes, and that the voicing manner of release, and place of articulation of the consonant remain evident when the syllable is truncated at the initial end to commence 50 msec before the peak intensity of the vowel of the syllable. The listeners were able to detect correct place of articulation more accurately than either voicing or manner of release as greater amounts of the initial part of a syllable were removed. The responses were related to the threshold of detectability.

TL;DR: The EmoVoice system, which implements acoustic rules to simulate seven basic emotions in neutral speech, showed that it can generate recognizable emotions but improvements are still necessary to discriminate some pairs of emotions.
Abstract: Generating emotions in speech is currently a hot topic of research given the requirement of modern human-machine interaction systems to produce expressive speech. We present the EmoVoice system, which implements acoustic rules to simulate seven basic emotions in neutral speech. It uses the pitch-synchronous time-scaling (PSTS) of the excitation signal to change the prosody and the most relevant glottal source parameters related to voice quality. The system also transforms other parameters of the vocal source signal to produce the irregular voicing quality. The correlation of the speech parameters with the basic emotions was derived from measurements of the glottal parameters and from results reported by other authors. The evaluation of the system showed that it can generate recognizable emotions but improvements are still necessary to discriminate some pairs of emotions.

TL;DR: A two pass strategy for recognition with a hidden Markov model based first pass followed by a second pass that performs an alternative analysis using class-specific features that provides superior separability to the traditional spectral features is developed.

TL;DR: In this article, two major acoustical correlates of voicing are examined, previously conflated in the Voice Onset Time concept: the time from the burst to the first voicing pulse and the relative position in the formant transition frame at which voicing onsets and is measured as the amount of voiced first formant (F1) transition.
