Since more than one year we see rising numbers in whooping cough globally. Today we can reed Ireland, Seattle and Louisina in the USA in the news. It is globally, last year we were informed by our school about a case of whooping cough in my son’s class. The cases are currently increasing across the Germany and whole world, if you check Google for the news.

Another case has now occurred with my son`s class. There is a certain unrest among the parents, especially due to the experiences of the last few years. The children are partly at an age where the effect of the vaccinations is waning, and some have infants at home, for whom it can be critical.

I have started with VOIZZR an app that measures deviations in the voice. I observe my voice daily and can tell when I am tired or going through a stressful phase. You can also recognize a good wine tasting. Various athletes already use the app for performance diagnostics, etc.

Now about whooping cough: My son had to be the test subject again for some tests, see the picture: Top left is my son, bottom left (view in the cockpit) and right (view in the app) is a boy of the same age with a verified diagnosis of whooping cough. It is noticeable that the values for the boy with whooping cough are almost zero and well below 0.1.

The number of Pertussi infections are increasing globally

The task sounds easy. We want to identify whooping cough cases as early as possible

Your voice is remarkably sensitive and responds to various influences. These can include stress, fatigue, or illness. Interestingly, a whooping cough infection can also impact the voice. In preparation for a new model of artificial intelligence, we now seek your support.

You can recognize many psychological and physical strains in the voice.

Given the sensitivity of this topic, athletes and trainers are eager to find a straightforward way to identify and communicate these phases. Our approach involves voice analysis.

Study Objective:

We aim to identify parameters and biomarkers in the voice and especially the coughing that significantly change before the infection of whooping is increasing. Our goal is to find a proper and reliable way to increase the healthiness of our kids.

How You Can Help:

If you’re an athlete, your participation matters. We simply need your daily voice recordings via the VOIZZR PITCH ANALYZER APP, along with some information about your current cycle phase. Don’t worry; it’s okay if you miss a day.

Test Preparation:

1. Download the app: Choose your preferred platform—Google Android or iPhone or Xiaomi

2. Select your language: In the app’s navigation menu, choose your desired language (currently available in English and German).

3. Configure Settings:

4. Daily tests: If possible, do the tests every day and at the same time. If you forget a day, this is no problem, testing at a different time is also no problem.

5. Monitoring: In VOZZR Analytics you will find the results of your voice audiofiles analysed by more than 50 AI algorithms.

We’ve received reports from several users and have also observed in friends and family members that symptoms of whooping cough occur with cough values that are almost at zero like in the following screenshot.

Please take into account: VOIZZR is not a medical product. VOIZZR is measuring technical signals in your voice and is showing deviations from YOUR “NORMAL”

Users who had a cold or the flu reported values very close to 1.

There are more things to monitore if you want.

Enjoy and they healthy.

Can the timing of menstruation and ovulation within the female cycle be predicted? What would be the implications if yes? And that too, days in advance? Just by using the voice?

The questions sound exciting. We want to find the answers together with female athletes.

Your voice is remarkably sensitive and responds to various influences. These can include stress, fatigue, or illness. Interestingly, the female menstrual cycle can also impact the voice. In preparation for a new model of artificial intelligence, we now seek your support.

The female menstrual cycle significantly affects the performance of female athletes. Depending on the cycle phase, athletes should consider the following:

1. Longer recovery periods: During specific phases, allocate more time for recovery.
2. Preference for endurance sports: Opt for activities that align with your cycle phase.
3. Strength training: Adjust strength training based on where you are in your cycle.
4. Risk of injury: Be aware that the risk of injury varies with the cycle phase and level of exertion.

Great importance is attached to the timing of ovulation. We want to determine this exact moment with the help of AI. For this, we need your support.

Given the sensitivity of this topic, athletes and trainers are eager to find a straightforward way to identify and communicate these phases. Our approach involves voice analysis.

Study Objective:

We aim to identify parameters and biomarkers in the voice that significantly change before ovulation. Our goal is to assist not only elite female athletes but all women in better determining the timing of ovulation. This knowledge can help tailor training, prevent injuries, and enhance overall well-being.

Some are optimizing their COVID testing processes with the VOIZZR App.

In our surroundings, whether in the social circle, workplace, school, daycare, sports club, or personally, the number of “positive” COVID cases is rising again. As expected, the numbers are increasing in the cold season. However, there are neither prescribed testing protocols from associations and the Bundesliga nor a sufficient number of available testing centers. How should we handle this, especially after Christmas celebrations and before Christmas with family? Or after holidays?

It’s a seasonal effect.

In professional sports, there are no fixed testing protocols anymore. However, some clubs and athletes rely on the VOIZZR PITCH ANALYSER or VOIZZR RPE App (optimized for professional sports). The goal is to identify potential cases early and raise awareness not only among athletes but also among family members and the coaching staff. Athletes, such as skiers, snowboarders, or biathletes, are often on the move, and some athletes could quickly test positive and be unable to compete. Athletes voluntarily use the app every morning to record coughing and read a predetermined sentence. This typically takes less than a minute. AI algorithms analyze the voice files in the background. If cough values are significantly in the upper range and a declining pattern appears in the P-Score, athletes are prompted to see the hygiene officer and discuss further steps. Often, a rapid test is then conducted to clarify the situation.

“Last season, we identified three cases before the Bundesliga’s testing protocol would have come into play,” reported a hygiene officer. “Additionally, we divided ‘Family and Friends’ of the players and the youth squads into separate groups for better oversight. Most infections come into the team through these contacts. The earlier we identify a player or the risk in their environment, the lower their personal risk, and the less likely they are to potentially infect others.”

“We simply sent the app links to our athletes in the youth squads, and they could start right away. Since we only see the athletes at regular intervals for training sessions at the training centers, we need a simple and pragmatic solution!” commented a national team coach. “We now receive the information before it reaches us!”

For those interested: Up to 10 tests per month are available for free. If you want to test friends and family with your own app, you can create additional profiles here.

In this spirit: Stay healthy, be mindful, and have a wonderful Christmas in the company of your loved ones.

This article presents a comprehensive systematic literature review (SLR) on the outcomes of using artificial intelligence (AI) for the recognition of diseases through voice analysis, with a focus on biomarkers. The SLR process involved the selection and analysis of relevant research studies, including their methodologies, datasets, and findings. This review highlights the effectiveness of AI-guided tools for screening COVID-19 infections using cough and sneezing sounds, discusses the state-of-the-art methods employed, and explores the potential of deep learning models in improving disease detection and prediction.

Eligibility of the Studies:

The SLR included a total of 28 studies that met the inclusion and exclusion criteria. The selected studies utilized various datasets, including cough sound data from laboratory-confirmed patients, crowd-sourced data, and data collected via mobile apps. While some studies focused on COVID-19 prediction, others provided essential information for the SLR without specific COVID-19 relevance. The analysis excluded studies with invalid measurements, unavailability of full text, and publication years before 2019. Eight studies were included based on references, resulting in a final set of 28 studies for synthesis.

Studied non-Laboratory Confirmed Dataset and State-of-the-Art Methods:

The review examined the use of deep learning methods, such as convolutional neural networks (CNNs), for the recognition of COVID-19 through cough and sneezing sounds. AI-guided cough screening tools employing CNNs showed promising results, with high sensitivity, specificity, and overall accuracy. The studies compared laboratory-confirmed datasets with non-laboratory-confirmed datasets, demonstrating the superior performance of AI-guided approaches when trained on reliable data. Ensemble learning, CNNs, and deep neural networks were utilized to identify COVID-19 in sneezing noises. The research also emphasized the potential of incorporating biomarkers and clinical data, such as respiration, speech, throat clearing, wheezing, and breathing, to enhance decision-making in disease screening.

Discussion and Conclusions:

Based on the selected studies, coughing was identified as one of the most prominent symptoms for the detection and prediction of COVID-19. AI-guided cough screening, along with clinical testing, can aid in the diagnosis of COVID-19, making it a valuable tool, particularly in resource-constrained areas. Deep features were found to extend the generalization of AI models without relying on past information, allowing for more precise predictions and insights. The use of AI-guided tools for COVID-19 screening showed superior performance when trained on laboratory-confirmed datasets. However, some studies lacked comprehensive method descriptions or employed biased models, highlighting the need for further improvements.

The review concluded that AI-guided solutions using biomarkers and clinical data, combined with advanced deep learning models like CNNs, hold promise for improving the analysis and prediction of COVID-19 and other diseases. Future research should explore the integration of ensemble deep neural networks and multimodal learning methods to enhance disease screening outcomes.

Overall, this systematic literature review provides valuable insights into the application of AI in biomarker recognition and disease detection from voice analysis. The findings demonstrate the potential of AI-guided tools for accurate and efficient screening, paving the way for advancements in healthcare and disease management.
