The human auditory system has a maximum sensitivity in the frequency range of 1,000 to 4,000 Hz (see Fig. 3.4 in Chapter 3), which is also the range of resonance frequencies (formants) of our vocal tract. The human voice and ears are well-matched organs. This chapter analyzes the ...
This Application runs in Maple. Don't have Maple? No problem! Try Maple free for 15 days! This application predicts the fundamental frequency of a human voice using the ComplexCepstrum command. After converting a small window of the audio to the cepstral domain, we find the pitch by noting...
Hierarchical cortical networks of "voice patches" for processing voices in human brain 2021, Proceedings of the National Academy of Sciences of the United States of America Frequency-following responses to speech sounds are highly conserved across species and contain cortical contributions ...

We have now removed the worst of the dirt. But our precious diamond still could use a little grinding. The area between 200 and 500 Hz is called “the mud” frequency range. There’s a lot of signal in my example above. Why? Because most of the energy in a human voice takes ef...
In the present study, we investigated the MMF evoked by voice changes during speech (i.e., a change in the fundamental frequency contour) in young children with ASD (aged 3–5 years) and a speech onset delay (AS-SOD), children with ASD without a speech onset delay (AS-NoSOD), and ...
There, it was shown that voices were processed faster in the go/no-go task compared to strings. Importantly, no voice advantage was found for the simple RT task, sug- gesting that the sound set was well-matched acoustically. The go/no-go RT difference was ascribed to recognition processes...
