Therefore, the scale parameter b has to be chosen as (c/sigma _{chi }^{2}), given an estimate of the speech STSA variance, (sigma _{chi }^{2}), and the shape parameter c.
The results establish the feasibility of detecting and mitigating speech-related variance in rapid event-related fMRI experiments with single word utterances.
If left unmodeled, speech-related variance can result in regional detection bias that affects some areas critically implicated in language function.
We investigated the timing, magnitude, and location of speech-related variance in an overt picture naming fMRI study with a rapid event-related design, using a data acquisition system that time-stamped image acquisitions, speech, and a pneumatic belt signal on the same clock.
where ({sigma _{v}^{2}}) and (sigma _{chi }^{2}), respectively, denote the noise and speech spectral variances and a Rayleigh PDF has been assumed for the speech STSA PDF p as in [3].
The present study indicates that multiple acoustic parameters vary in natural competitive- and courtship-generated men's speech, and that variance in these parameters may be differentially attended to by men evaluating dominance and women evaluating attractiveness.
Factor 5 (11.5% of variance) contained speech abnormalities (pressured speech) and insight and negative loading for sleep.
At the same time, it maintains a stochastic distribution of interstimulus intervals to avoid confounding task covariates with speech-related signal variance.
Another possibility is to use a decoder of the form [32]. Fig. 6 A comparison of analytical and experimental AMMSEs of HDA systems designed for unit-variance speech signals, HDA-PQ (left) and HDA-TC (right).
Electrical-field interaction accounted for as much as 70% of the variance in speech recognition scores, suggesting that electrical-field interaction is a significant contributor to the variability found across patients who use simultaneous strategies.
