The bioacoustic analyses and its relative figures were performed using Raven Pro 1.4 (Cornell Lab, 2011) software with sampling rate of 44.1 KHz and 16 bits of resolution, with FFT size of 512 points and Window type in Hanning for better spectrogram
Now, with the help of computer tomography, a magnetic vibration spectrogram
or an angiogram, a "map" of the patient's brain will be created.
Given an STFT [F.sup.g.sub.x], the spectrogram
[S.sup.g.sub.x] is defined as:
SLIVERprofessional also provides assistance with analyzing faults, for example by displaying periods and draft waves in the spectrogram
. Operators can thus quickly rectify faults and increase the availability of the machine.
first is the acoustic spectrogram

The top image in Figure 2 is a spectrogram
of the sentence "Please select the word went," as spoken by Female 1 in the Institute for Telecommunication Sciences (ITS) ABC-MRT speech database.
Based on these encouraging results, in this paper we propose a new, fully automated method for the classification of EEG spectrogram
images for the detection of motor impairments in patients using a deep convolutional neural network architecture.

) and include a Frequency Mask Trigger.
According to a paper published in arXiv.org, the system first creates a spectrogram
of the text, a visual representation of how the speech should sound.
The Fourier analysis display of the speech signal is called a sonogram or spectrogram
. A spectrogram
is a three-dimensional spectrum that represents a graph of the frequency spectrum of a voice over time, with the vertical axis as the frequency and the horizontal axis as the time.
It should be noted that, in the building of a spectrogram
, it was not the window Fourier transform of one long record, but the successive fast Fourier transform of the individual AE waveforms.
better preserves energy distribution (comparing to wavelet transform), but it has issues with time/frequency resolution and gives rather rough estimates.
