The Fourier transform is essential to understanding more
complex wave structures, like human speech. Given a complicated, messy wave
function like a recording of a person talking, the Fourier transform allows us
to break the messy function into a combination of a number of simple waves,
greatly simplifying analysis. When processing signals, such as audio, radio
waves, light waves, seismic waves, and even images, Fourier analysis can
isolate individual components of a compound waveform, concentrating them for
easier detection and/or removal. A large family of signal processing techniques
consist of Fourier-transforming a signal, manipulating the Fourier-transformed
data in a simple way, and reversing the transformation. The method gets its
name from a French mathematician and physicist named Jean Baptiste Joseph (Baron)
de Fourier.
The Fourier transform is at the core of modern signal
processing and analysis.
Articulatory Phonetics is the study of the sound waves produced by human speech, and is the key to understanding a valid AVP response. I have developed methods, and procedures with the purpose of collecting data that can easily evaluated professionally. Along with the use of Spectrum Analysis an advanced mathematical technique for the study of frequencies according to its component wavelengths producing a visual representation, call a spectrogram, or (sonogram.) Primarily used in astronomy, music, electronics, and signal research.
I will provide just enough basic information to familiarize you with basic articulatory phonetics, and the phonology of North American English, phonemes and basic contrasts without getting into major allophonic variation such as vowel nasalization, and nasal place assimilation.

A formant is a dark band shown here in yellow on a wide band spectrogram, which corresponds to a vocal tract resonance. In speech, primarily the vibration of the vocal folds provides the source of sound.
Spacing between the harmonic changes up, or down with the pitch of the voice.
Technically, it represents a set of adjacent harmonics, which boosted by a resonance in some part of the vocal tract. Thus, different vocal tract shapes will produce different formant patterns, regardless of what the source is doing. There's the turbulence generated by the air as it moves past the walls of the vocal tract, usually called 'channel frication'. This is just 'drag', resistance to the free flow of air. Frication noises are generated in two ways, either by blowing air against an object ‘obstacle frication’ or moving air through a narrow channel into a relatively more open space ‘channel frication’.
Voicing represented on a wide band spectrogram by vertical striations, especially in the lowest frequencies. Each vertical 'line' represents a single pulse of the vocal folds, a single puff of air moving through the glottis.
Frication noise is generated in two ways, by either blowing air against an object (obstacle frication) or moving air through a narrow channel into a relatively more open space (channel frication).
Plosives refer to voice less sound from produced by complete closure of the oral passage and subsequent release accompanied by a burst of air.
Nasals (Nasal stops) have some formant structure, but are better identified in lower amplitude than in the vowel. Best described as a resonance left over in the nasal tract.
The first formant correlates to height (openness) of the vocal tract. The formant with the lowest frequency called f1, the second f2, and the third f3. (Fig. A)
The next highest formant in the vowel space correlates vowel quality, and vowel duration. Vowels will usually have four or more distinguishable formants; sometimes there are more than six. The first two formants are enough to determine vowel quality.
The final burst is the release of the final plosive, and the last bit of noise echoing around the vocal tract. In a wide band spectrogram as weaker formants and turbulence generated by the air as it moves past the walls of the vocal tract called channel frication. If you want to know, more take a class in acoustic phonetics. (Above in Fig. B)
Comparing Human Speech to the Anomaly
When comparing human speech to the response from the entity. You can clearly see vowels in human speech will usually have four or more distinguishable formants followed by vertical striations caused by air movement through the glottis to drive vibration. It is the lack of these characteristics such as vibration of the vocal folds. That distinguishes human speech from a valid electronic voice response. In the anomalys' response, that there is no physical signs of a throat, mouth, or breath. You must understand there are numerous skeptical explanations for EVP all them are true when it comes to the inexperienced paranormal team. For a professional organization to be taken seriously needs to address every skeptical concern. There will always be new questions, and skeptical concerns about anything and everything. There are techniques used that are designed to intentionally dismiss all your work by making it sound utterly ridiculous. Such methods are obvious and only used by weak minded malcontents that struggle with any sort of original thought.
How voice recorders can record what or ears cannot hear. The average frequency ranges on these devises are between 40Hz – 21,000 Hz well within the range of human hearing 20Hz – 20,000 Hz. Electronic voice phenomena described as being at a range of 60Hz and lower. Showing up on a wideband spectrogram on average within the range of 1-4 kHz, it is not so much that it is above or below the range of human hearing just that the amplitude is too faint to be heard by the human ear. When the volume played back, it is turn all the way up the same goes for audio editors. We found it necessary to use headphone amplifiers in aiding us in identifying the sound anomalies, audio spectrum analysis, and procedures developed along with training to ask questions that would require an extended answer at the point where we would be listening for the response. An extensive understanding, and comprehensive knowledge of Acoustic and Articulatory Phonetics are requires in separating the differences between noise and human speech patterns from the artificial characteristics of a true EVP. The experiments we have conducted show that the entity exists well within our physical plain of existence.
There is a blind physicist friend David Kent Cullers that joined us on a couple investigations. I had an idea on how I could explain human speech in a formant structure when referring to a valid AVP response in an audio spectrogram. Picture in your mind a 6-foot stepladder. The shorter ladders are wider at the bottom, and narrower at the top. The ladder has rungs, or steps separated by space. The formants in a spectrogram for human speech look like a ladder, but at differing widths depending on the length of the word pronounced. The lower or bottom three to six steps are vowels they are mirrored above by three to six steps, but weaker, and shorter as they move up the ladder. This is friction as air moves through the glottis over the tongue through the teeth and the lips, or through the nose. Above that is a uniformed pattern that moves all the way up the spectrogram created by airflow. A valid electronic voice response has one-step maybe another shorter second step, but no friction or vertical uniformed pattern created by airflow. Therefore, we are saying that it has no mouth or breath.
Altering low frequency responses by simply changing the pitch of any noise by slowing it down, or speeding it up can manipulate the sound to come up with whatever you might think it said, or want it to say. The idea is to control your environment, tag your audio; backing up your audio with video can help validate responses, use audio spectrum analysis to rule out questionable sounds that could be mistaken for evidence. The more control you have over the environment the less time spent on audio analysis. We use Adobe Audition audio editing software that will allow you to remove noise from around the sound you want to bring out for use on videos. If the EM response intended as evidence is not clear enough that everyone without help, guessing, or manipulating the sound, can understand it. Throw it out!
There is a University Study published in Sept. 2012 of a series of experiments carried out in Vigo, Spain. Throughout a period of two years under conditions controlled to the highest degree achievable entitled: "A Two-Year Investigation of the Allegedly Anomalous Electronic Voices or EVP" by Corresponding author: Anabela Cardoso they outlined some of the problems they've had with stomach noises, whispering, sound being mistaken for voices, and contamination. Addressing the contamination problem with new procedures, the same methods we have already adopted to address skeptical explanations for anomalous voice phenomena - AVP what others call an EVP. Their conclusion in this study was that the data was real, and yet unexplained.
I encourage everyone to read this research, everything we had already discovered, and addressed with changes in procedures, training, and methodology. Learning to relax your breathing, drinking plenty of water, and practicing speaking at a moderate tone between 50-60dB with the use of a decibel meter, no yelling out your EVP questions their dead not deaf, and no whispering ever.
Convincing Evidence of an Afterlife (More Questions than Answers)
Analyzing one of our intelligent responses caught on audio known as anomalous voice phenomena - AVP. The audio when we listened to it exhibited so much diversity in its response. In both cognitive, and physical traits that are only found in living human beings. The most remarkable is precognition that we thought was impossible without a physical presence. Then there is the absence of sensory organs, which would be necessary to accomplice such a physiological process. The entity first displayed the ability to see the actions taken by the researcher as the attempt was made to open a locked dresser drawer. The capacity to comprehend, and yet display precognition is the foundation of human consciousness, and our higher cognitive abilities. This is firmly established within its first spoken response. 'It's Locked' the entity again displays comprehension and the ability to hear as the researcher acknowledges the locked drawer by responding with a confirmation, and an emotional expletive. The entity responded with 'It is, Fuck You!' Not one single physical region of the human brain could explain the complexity of this response. To date there is no proof that our brain can survive physical death, so the explanation must lie within the yet undiscovered properties of the brain.
One more piece of evidence I wanted to point out. The room they were in was 20x15x15 foot (6.1x4.6x4.6 meters) was full of large pieces of furniture the observation would have had to been made just behind the left shoulder of the researcher. Again female speech shows formant structure the entity none.
When comparing the formant between this EVP, and Human speech in a wide band spectrogram. The formant in the EVP shows no vertical striations.
The female response of the acknowledgment 'It’s locked'. The first word 'Its' shows three clear formants with vertical striations comprised of one formant obstacle frication.
In the second word of the female response 'locked' shows six clear formants with vertical striations comprised of three-formant obstacle frication.
The obstacle frication in the vertical striations signify obstructions caused by air movement through the vocal cords, tongue, teeth, and lips unlike the entities response that shows no vertical striations or obstacle frication.
Vowels in human speech will usually have four or more distinguishable formants followed by vertical striations caused by air movement through the glottis to drive vibration. Again, the EVP shows no vertical striations.
It is the lack of these characteristics such as vibration of the vocal folds. That distinguishes human speech from a valid electronic voice response
