Effects of low-pass filtering on the judgment of vocal affect in speech directed to infants, adults and foreigners. ACCEPTED MANUSCRIPT 2 ABSTRACT Low-pass filtering has been used in emotional research to remove the semantic content from speech on the assumption that the relevant acoustic cues for vocal affect

Pairs of Thai tones were presented for perceptual discrimination in three linguistic contexts (normal speech, low-pass filtered speech, and as musical (violin) sounds) to tonal language speakers, Thai and Cantonese, and non-tonal (English) language speakers. English speakers discriminated the tonal contrasts significantly better in the musical context than in filtered speech, and in filtered sp...

This study investigates the variance and invariance in speech rate as a reflection of conceptual planning and cognitive rhythm. A four-frame comic strip was used to elicit speech and low-pass smoothing was done afterwards to filter out high frequency noise. Results showed that subjects invariably planned narration in terms of story plots. Variance lies in the way subjects synchronize planning a...

This letter describes a zero-speed start-up method of a speed sensorless stator-flux-oriented direct vector-controlled induction motor drive with the help of a machine current model that does not use any speed signal. The machine starts smoothly with vector control at finite developed torque and then transitions to the standard direct vector-control mode with the voltage model signals as the sp...

Can the foreign accent of a speaker be recognized based on suprasegmental temporal information? For a perception experiment we created stimuli based on German sentences read by six French and six English speakers. These foreignaccented sentences were manipulated by (1) applying a lowpass filter with a cutoff frequency of 300 Hz and (2) applying the same lowpass filter and monotonizing F0. In a ...

This paper deals with voltage model flux estimators for speed sensorless induction motor drives. In order to eliminate the drift problems, the pure integrator of the voltage model is replaced with a first-order low-pass filter, and the error due to this replacement is compensated. An effective way to calculate the compensation is presented, and the compensation is carried out before the low-pas...

This paper presents semicircular microstrip low pass filter with the sharp rejection and wide stop band. The proposed filter design is based on the calculations of filter parameters from traditional Hi-Lo impedance method and is available in the literature of microstrip filter. To further improve the design performance, high impedance lines are magnetically coupled, resulting an attenuation pol...

So effectively, you can say that the capacitor acts as a low-pass filter when it in a transistor circuit, it blocks the DC and acts as a low impedance path for AC. Official Full-Text Publication: Single Transistor Active Filters: What is Possible and The results presented here fill both a circuit-theoretic gap and an application-oriented gap related to single a case is the low-pass filter numbe...
