Earlier work reported in the STL‐QPSR (Speech Transmission Laboratory, Quarterly Progress and Status Report, KTH, Stockholm) each year since 1979 has been extended to the modeling of the supraglottal impedance to include five formants and a time span of analysis to embrace several successive glottal periods. The acoustic interaction is highly nonlinear and may give rise to spectral peaks between formants. This is largely due to nonlinear superposition ripple originating from previous…

A source model taking the acoustic interaction into account is briefly described. As an integrated component, the approach to deriving a lumped-parameter representation of the VT load is also

Measuring and modeling vocal source-tract interaction

The purpose of this paper is to present an algorithm for automatically measuring source-tract interaction for voiced speech, and to present a simple speech production model that incorporates source-Tract interaction into the glottal source model.

Notes on glottal source interaction ripple 1

Interaction ripple is caused by the nonlinear relation between glottal flow and transglottal pressure, the latter containing components of vocal tract oscillatory modes evoked during the past history

On the production mechanisms of the singer’s formant

A small extra tube directly located above the glottis (laryngeal tube), which is about six times smaller in cross-sectional area than the pharyngeal-oral tube section and which has a length of about

Sensitivity of Source–Filter Interaction to Specific Vocal Tract Shapes

Results show that the ventricle, the false-fold glottis, the conus elasticus entry, and the laryngeal vestibule are the regions to which acoustic variables are most sensitive.

Articulatory Speech Synthesis from the Fluid Dynamics of the Vocal Apparatus

It is proposed that the articulatory speech production model has the potential to synthesize speech and provide a compact parameterization of the speech signal that can be useful in a wide variety of speech signal processing problems.

A study of temporal structure of glottal flow derivative estimates obtained via inverse filtering

The extent by which Liljencrants-Fant's model can be used to represent the glottal flow derivative estimates obtained via closed-phase pitch synchronous inverse filtering of recorded speech is ascertained.

A study of voice source interaction

INTRODUCTION Inverse filtering combined with extraction of LF-source parameters, e.g. Gobl(1988), Karlsson(1992) have provided a knowledge base for improved quality in speech synthesis, Carlsson,

Truncation and superposition effects in voice production

A time‐domain analysis of format amplitudes has to cope with both truncation effects from excessive damping in the glottal open period and superposition effects, i.e., the carryover of residual
