Exploiting Glottal Formant Parameters for Glottal Inverse Filtering and Parameterization (2010)

Exploiting Glottal Formant Parameters for Glottal Inverse Filtering and Parameterization (2010)

O'Cinneide, Alan; Dorran, David; Gainza, Mikel; Coyle, Eugene

Abstract:

It is crucial for many methods of inverse filtering that the time domain information of the glottal source waveform is known, e.g. the location of the instant of glottal closure. It is often the case that this information is unknown and/or cannot be determined due to e.g. recording conditions which can corrupt the phase spectrum. In these scenarios, alternative strategies are required. This paper describes a method which, given the parameters of the glottal formant of the signal frame, can accurately parameterize the glottal shape source and vocal filter for a broad range of voice quality types and which is robust to the corruption of the phase spectrum. Index Terms: glottal inverse filtering, frequency domain, glottal models, glottal formant

Voice-to-affect mapping: Inferences on language voice baseline settings (2017)

YANUSHEVSKAYA, IRENA; GOBL, CHRISTER; NI CHASAIDE, AILBHE

Abstract:

Modulations of the voice convey affect, and the precise mapping of voice-to-affect may vary for different languages. However, affect-related modulations occur relative to the baseline affect-neutral voice, which tends to differ from language to language. Little is known about the characteristic long-term voice settings for different languages, and how they influence the use of voice quality to signal affect. In this paper, data from a voice-to-affect perception test involving Russian, English, Spanish and Japanese subjects is re-examined to glean insights concerning likely baseline settings in these languages. The test used synthetic stimuli with different voice qualities (modelled on a male voice), with or without extreme f0 contours as might be associated with affect. Cross-language differences in affect ratings for modal and tense voice suggest that the baseline in Spanish and Japanese is inherently tenser than in Russian and English, and that as a corollary, tense voice serves a...

On the Appearance of a Positive Real Pole in the Results of Glottal Closed Phase Linear Prediction (2010)

On the Appearance of a Positive Real Pole in the Results of Glottal Closed Phase Linear Prediction (2010)

O'Cinneide, Alan; Dorran, David; Gainza, Mikel; Coyle, Eugene

Abstract:

Often when performing glottal closed phase covariance linear prediction, a positive real pole can appear in the resulting filter transfer function. The commonly adopted approach is to discard this pole, as it does not fit with the usual model of the all-pole vocal tract filter. However, this real pole describes some aspect of the speech signal; this paper provides a novel perspective on its occurrence. This viewpoint has a useful implication to the speech community, especially from the perspective of fitting a glottal pulse to the inverse filtered signal, as the real pole describes the return phase of the glottal flow for certain voice types that adhere to a reasonable criterion. Tests with synthetic signals are performed to validate this approach.
