The voice consists of sound made by a human being using the vocal folds for talking, singing, laughing, crying, screaming, etc. Habitual speech fundamental frequency ranges in 75–150 Hz for men and 150–300 Hz for women. The human voice is specifically that part of human sound production in which the vocal folds (vocal cords) are the primary sound source.

We are trying to use stem-loop primers for miRNAs expression investigation.
The RT reaction was performed using treated total RNA and the RT primer stem loop specific for our targeted miRNA (miR-125a). The 10 µl of RT reaction mixture contained 1 µl of treated RNA (0.1 ng–5 µg), 1 µl of RT primer (5 µM) and 1 µl of U6 (reference miRNA) RT primer (5 µM), 1 µl of 10 mM dNTP Mix, 2 µl of reaction buffer, 0.5 µl M-MLV Reverse Transcriptase. The mixture was incubated at 25°C for 5 min, and then incubation was continued at 42°C for 60 min. The reaction was inactivated by heating at 70°C for 5 min.
The 10 µl PCR volume included 1 µl of RT product, 5 µl of SYBR Green real-time PCR Master Mix, and 1 µl of primer (forward and reverse, 1 µM each). The reactions were incubated at 95°C for 3 min, followed by 40 cycles of 95°C for 5 s, 62°C for 35 s.
results were not satisfying . Negative control revealed expression and samples did not.
Do you have any suggestions regarding the protocol whether reverse transcription or PCR?
I understand non-associative learning is learning from a single stimulus. Many sources I can find show that habituation and sensitisation are forms of non-associative learning. Examples of single stimulus habituation are simple to imagine, but single stimulus sensitisation not so much. Many of the examples of sensitisation that people mention are actually examples of associative learning. I think the problem stems from the terminology, which suggests the following:
Desensitisation = opposite of sensitisation.
Habituation = opposite of sensitisation.
Therefore, habituation = desensitsation
I do not think that habituation is the same as desensitisation, but the terminology seems to be saying this is the case. I thought habituation was single stimulus learning, but desensitisation was the unlearning of a classically conditioned response (and therefore a type of associative learning).
Can anyone shed any light on this for me?

Hello,
I performed a GC-MS analysis for my plant extracts (stems and leaves) my questions are:
1- How can we identify the molecules if the probabilities are very close and we don't have a lot of information in the literature with which we can compare?
2- Can I compare my results with those of other species of the same family?
3- Can a molecule be observed at 2 different retention times?
4- A few molecules are present on the stems and absent on the leaves, is this normal?
Thank you in advance
What is its unit of measure?

I'm a 3rd-year psychology student at the University of East London and I'm conducting a 10-15 minute anonymous online survey to capture the everyday experience of Fibromyalgia patients and how they feel they are supported by their medical experts for my final year dissertation.
As leading voices for those who experience chronic illness and who may also be diagnosed with fibromyalgia, I would like to request your assistance in reaching those who often lack a voice, to allow me to capture their thoughts and feelings. Can you help me reach the 150 people that I need to complete the survey over the next two months.
All participation is anonymous and will be carried out under the strict guidelines of the British Psychological Society and the University of East London Ethics Committee.
As you are aware Fibromyalgia lacks robust research, I very much hope that gathering as many voices as possible through completion of the survey will be an opportunity to start addressing that.

I am trying to build a model that can produce speech for any given text?
i could not find any speech cloning algo that can clone the voice based on speech only so I turned to TTS(Text-to-speech) models. I had the following doubts regarding data preparation?
As per LJSpeech dataset which has many 3-10 sec recordings we require around 20 hours of data. It will be very hard for me to build these many 10 sec recordings. What would be the impact if I make many 5 min recordings. One could be high resource req (but how much), are there any others.
Also is there some way through which I could convert these 5 min recordings as per LJSpeech format

Hello,
I read some papers they used Pre-processing steps with text that will classify based on Sentiment Analysis.
My question is, can I use text Pre-processing techniques in the sentiment analysis classification, such as the Stop Words Removal and Stemming techniques? If can, it will cause Negations Words or Negation Prefix to be deleted, such as ( I am Not happy), will be (happy) after we use Stop Words Removal technique or (unlucky) will be (lucky) after we do Stemming process. That's mean the sentence that should classified into negative class will be classified into positive class. How to deal with that?
Thanks to answers in advance.
Hi, do you know any literature or article, that analyse any kind of unorthodox ADR, revoicing? Extreme example is when there's woman on screen but we hear male voice. Subtle use of this could be actor doing some kind of extreme action but his voice is calm. Or something similar. Thanks a lot!
Are there open source datasets and pre-trained deep learning models available for voice sentiment classification ?

Several reports exists relating to the frequency fundamental of male and female speech. Though they not all agree, there is a clear trend that the fundamental frequency of men's voices is lower than females. One example: "The voiced speech of a typical adult male will have a fundamental frequency from 85 to 155 Hz, and that of a typical adult female from 165 to 255 Hz."[1]
QUESTION: Is it meaningful to study speech below these frequencies and why?
I am studying speech directivity and for some reason in the literature the male and female voice seems to repeatedly compared at 125 Hz, near the male fundamental. This seems nonsensical to me but maybe there is a good reason for this? I have recorded a fair bit of female speech and I see very little sound energy in this frequency band.

Hello everyone,
for my thesis I want to extract some voice features from audio data recorded during psychotherapy sessions. For this I am using the openSMILE toolkit. For the fundamental frequency and jitter I already get good results, but the extraction of center frequencies and bandwidths of the formants 1-3 is puzzling me. For some reason there appears to be just one formant (the first one) with a frequency range up to 6kHz. Formants 2 and 3 are getting values of 0. I expected the formants to be within a range of 500 to 2000 Hz.
I tried to fix the problem myself but could not find the issue here. Does anybody have experience with openSMILE, especially formant extraction, and could help me out?
For testing purposes I am using various audio files recorded by myself or extracted from youtube. My config file looks like this:

When a Maize plant is given normal condition for growth development, stand & establishment, it grows without tillering. But, when it get infected by any infestans for eg, Stem borer or FAW that infestes on Plant whorl making it unable to grow any further tall.
Hello, Please I need help with a statistical analysis. I don't know which statistical test to use.
The study I did is as follows :
an extraction by maceration of the leaves and stems of a plant and an ultrasonic assisted extraction of the leaves and stems as well. I then performed the following tests in triplicate (polyphenols, flavonoids, flavonols, condensed tannins and DPPH).
I want to make the following comparisons:
- leaves with stems
- Leaves (maceration) with leaves (sonication)
- stems (maceration) with stems (sonication)
My research direction is to modify existing molecular beacons but I cannot seem to get the solid phase synthesis of the quencher-free molecular beacon with flurophore attached at the loop region. It appears they are lots of work on this but the synthesis is not clear. I need help on whether the fluorophore is attached before the stem region or after the stem region.
I do my research and have a big problem to collect speech sample of cleft palate child.
thank you for your help.

We are planning a study in which we want to isolate PBMCs from study participants blood in order differentiate osteoclasts. As we are interested in differences between two groups of participants, we are worried about inter-assay differences, which do not stem from participants but rather from the assay itself. We are not able to collect blood from all the participants at the same time. Is there a way to minimize any inter-assay differences or at least to somehow control for them?
Thank you very much in advance.

In an upcoming research project we need voice recordings. The recordings will be transcribed and used together with the texts for statistical analysis.
According to ethical principles, personal data must be anonymised or at least pseudonymised after a certain time as indicated in our informed consens. This is problematic in the case of sound recordings because a person can be recognised by his or her voice.
Is there an uncomplicated way to make the voice recordings anonymous or pseudonymous?
What are ethically acceptable alternatives?
I have a complex channel matrix 'H' and I want to quantize it in such a way so that the quantization error is minimum. In particular, how to select the dynamic range (the maximum and minimum interval) of the quantization level. Also, what is the best way of finding the appropriate values of each quantized point?
A MATLAB code-based supported answer would be icing on the cake. :)
-------
Below is what I am doing, at the moment, but it is not the best way.
Example:
H =
[-0.9767 + 1.0234i, -1.0477 - 0.4223i;
1.0364 + 0.0454i , 0.0095 - 0.4758i;
0.2724 - 0.4980i , -0.4430 - 0.7466i;
-0.7302 + 0.7945i , -0.2508 + 0.1906i]; %Matrix H having 4 rows and 2 columns
H = H.';
H = reshape(H,1,[]);
partition = [0:1]; % Quantization levels
codebook = [0:2]; %Values for each quantized point.
[index,Q_H_real] = quantiz(real(H),partition,codebook); % Quantized real of H.
[index,Q_H_Im] = quantiz(imag(H),partition,codebook); % Quantized img. of H.
Q_H=Q_H_real+i*Q_H_Im;
%Fig. 1. Plot real part of H and its quantized version
stem(real(H),'b');
hold on
stem(Q_H_real,'r')
legend('Original (Real Part) H','Quantized (Real Part) H')
title('Quantization of Real Part of H')
%Fig. 2. Plot Imaginary part of H and its quantized version
figure;
stem(imag(H),'b');
hold on
stem(Q_H_Im,'r')
legend('Original (Img Part) H','Quantized (Img Part) H')

I am working on a project related to Mine to Mill optimisation. I would like to predict and incorporate the heterogeneity of fragmentation in the associated analyses.

Any idea is highly welcome.
