Tips to Speak and Communicate Confidently
The voice reflects a person’s inner energy. The voice is also a tool for self-expression. The louder a person speaks, the more attention they want to attract and the stronger they want to feel their importance. How can we establish the right dialogue between the body and the voice, and what does biohacking have to do with it? Our experts explain!

What Is Communication Biohacking?
We all more or less guess or even know for sure that the quality of our voice and the condition of our body are directly related. However, understanding this with your head and feeling it with your body are completely different levels of understanding.
Body-Voice-Conversation as a System Skill
Body language and speech are closely related: for example, nonverbal signals (gestures, facial expressions, posture) complement, reinforce, and sometimes contradict what is said, revealing true emotions and intentions; The body conveys subconscious messages, building trust and empathy and influencing the perception of the interlocutor, and can even affect our internal state. For example, “power poses” increase confidence, while inconsistencies in signals reveal lies. Albert Mehrabian proposed that nonverbal communication, such as tone of voice and facial expression, accounts for 93% of all communication. This means that spoken words account for only 7%!
A speaker at a biohacking conference who sends negative body language signals during a presentation (turning their back to the audience or slouching) is less likely to engage the audience and encourage them to listen attentively. Not only does this speaker lose the audience’s interest, but they also distract them from the topic, no matter how important it may be. No one wants that to happen.
This means that although we use verbal communication (words) to express our opinions, body language often conveys much more information to the audience than we realize.
How Biohacking Enhances Communication Skills
Biohacking can improve communication skills in one way or another by increasing mental clarity, energy, and emotional regulation through better sleep, nutrition, and mental health, allowing you to better understand yourself and others, be more attentive, and be less irritable. In addition, participation in biohacking communities and conferences develops communication skills through the exchange of experience and knowledge with like-minded people, as well as through public speaking and presentations.
Nowadays, biohackers are increasingly and more actively sharing their knowledge and experience in open communities, forums, and blogs. They believe that sharing information contributes to the development of science and technology and helps others improve their health. Communication and the dissemination of new knowledge will save the world and make it healthier!
Body
Biohacking aims to improve the body, enhance its functions, and realize its maximum potential for longevity. This requires a comprehensive approach that encompasses physical, biological, and psychological levels. Body language, how we behave, and what we show are directly related to our physical condition and emotional stability. How can we support our body and monitor our gestures?
Relax Your Body to Speak Clearly
If you have ever watched a presentation where the speaker is rushing, using quick gestures, and cannot stand still, you probably know what we are talking about. Fast, decisive actions that convey urgency signal that you feel uncomfortable in a given situation and can elicit a similar feeling in your audience. You may feel uncomfortable, but you don’t want your audience to know it.
Take a break! Take time to relax before an important presentation or project deadline, put aside unnecessary thoughts, take a break from your gadgets, and take a relaxing bath. Your body needs to rest to return to a normal state. This will make your movements calm, smooth, and appropriate. By slowing down your body movements in front of an audience, you will become more relaxed and confident in your words — and so will your audience!
Use Open Body Language
What is the difference between an open and a closed posture?
- An open posture is a relaxed person using open body language, such as turning to face the other person or spreading their arms to the sides to appear accessible and receptive.
- A closed posture is when a person crosses their arms or turns away from the other person during a conversation. This indicates a defensive reaction and indifference to the other person or the conversation. Open postures and gestures make it easier to establish contact. Try to move gently and not tense your body. If you are communicating one-on-one, also maintain an open posture, make eye contact, use open hand gestures during the discussion, and smile.
This means no crossed arms, no hands on hips, no abrupt gestures, and no avoiding eye contact! A distant posture can give the impression that you are not interested in what they are saying, even if this is not the case.
Good Posture
A straight back is a sign of a confident speaker and a healthy, active person. Watch your back, because first of all, it won’t hurt, and secondly, it will give you status and cheerfulness!4
Additional tip: if you find it difficult to remember to maintain an open posture, try the mirroring technique.
This is when you pay attention to other people’s body language and subtly mirror it — copying their facial expressions or poses. This does not mean copying every move they make. Still, you need to do it discreetly to establish mutual understanding with the person.
Practices for Better Body Awareness
Regular physical activity is beneficial for strengthening the immune system, maintaining a healthy weight, improving physical health, and promoting psychological and emotional well-being. Exercise not only helps you lose weight, tone your body, and straighten your back, but also distracts you, helps you forget negative emotions, and balances your hormones. Adults need at least 150-300 minutes of moderate-intensity physical activity per week or at least 75-150 minutes of high-intensity activity, if there are no contraindications. This can be, for example, yoga, stretching, or Pilates. Breathing exercises are also beneficial.
Voice
A good voice is a person’s calling card, so it is important to pay attention to your voice. The voice is critical to a speaker because it is the primary tool for conveying emotions, persuading, establishing trust, and holding the audience’s attention. It shapes the perception of the speaker as confident or insecure, and its absence or monotony kills interest, making even the most interesting and well-written speech empty and ineffective. The timbre, intonation, and volume of your speech convey more information than your words alone, influencing the charisma and success of your performance.
Breathe Before You Speak
Start with simple sounds, such as humming on a single note (e.g., “mmmm”), gradually expanding the range and intensity. A simple life hack: inhale through your nose for a count of 4, filling your abdomen and chest with air. Hold your breath for a count of 7. Exhale through your mouth for a count of 8, aiming for an even, smooth exhalation. This practice improves breath control and helps you calm down before a speech. Avoid shouting and sudden transitions, as this can damage your vocal cords.
Start with a Pause
Another effective tip from experienced speakers is to pause. Sometimes silence is more eloquent than words. To start your speech with a pause, simply take a deep breath, look at the audience, and give yourself a few seconds of silence before saying your first word. This will show your confidence, help you gather your thoughts, add meaning to your words, and attract your listeners’ attention, who will instinctively fall silent in anticipation, turning silence into a powerful tool.
Finish Sentences with a Downward Tone
Have you noticed how your voice drops at the end of a sentence? That’s downward intonation in action! When we use downward intonation, our voice drops in tone, often at the end of a sentence. This creates an impression of confidence and logical completeness, which helps the listener understand that the information is final.
The key is to do this logically. For example, interrogative intonation rises toward the end of speech, while affirmative statements often end with a lowering of tone.
Slow Down Speech
To slow down your speech, practice deliberate pauses, take deep belly breaths, focus on enunciating clearly by opening your mouth more, use props like a water bottle for natural breaks, and practice exercises like “turtle talk,” all while being patient and listening to yourself speak to build awareness and control.
Improve Articulation and Clarity
Clear articulation is important because it improves communication, helps you connect with others, and conveys confidence and authority. Working on your articulation will help you become a better communicator in both your personal and professional life, whether you are giving a presentation, having a conversation, or giving a speech.
To improve articulation and clarity of speech, regularly perform articulation exercises for the lips, tongue, and jaws; practice tongue twisters; read aloud slowly and clearly; and use a pencil to complicate pronunciation and control breathing. Working with a speech therapist or taking public speaking courses will also provide targeted support.
Vocal Exercises to Unlock Your Natural Voice
One of the ways to improve communication skill is to unlock your natural voice, practice warm-ups like lip trills, humming, and sirens, focusing on diaphragmatic breathing, maintaining good posture, and releasing jaw/tongue tension for better resonance and range, all while staying hydrated and consistently applying techniques to find clearer, fuller tones. You can practice simple vocal exercises at home or in your car for this!
Conversation
Our brains are programmed to process information efficiently. When we hear clear, well-articulated speech, our brains can quickly and accurately decipher messages. This creates a positive cognitive perception and makes us more inclined to enjoy listening to that person’s voice. In addition, a well-constructed dialogue, the right questions, and clear, accurate speech can convey confidence and authority, attractive qualities in a speaker.
Start with the Headline
The first words spoken to the audience are the most important for the speaker. They set the tone for the entire speech and establish contact with the audience. You need to talk about the most important things, the things that matter.
You are the center of attention, and you need to take advantage of that. At the same time, you have only just appeared before your audience, and they do not yet know who you are. Their questions at this moment are, “Who is this speaker?” and “Is he an expert or not?” You need to motivate the audience — tie your greeting to the topic you are speaking about and show that the presentation will be relevant and important to them. This will dispel any fears that the speech will be boring and fail to provide new knowledge. You will also show yourself as a professional. Contact with the audience in a public speech is established when the audience realizes you can be trusted and are likely to say something interesting.
The main rule when communicating with someone for the first time is to start with something positive. If you start the conversation with something you don’t like, you won’t be able to establish open communication. The person may agree with your opinion, but their mood will worsen. You will be remembered for causing negative emotions, which means they will try to avoid communicating with you again.
Use the PREP Method
PREP (Principle of Preceding Conclusion) is a structured way of expressing an opinion by (1) first stating the conclusion, (2) then explaining reasons based on data, (3) reinforcing the impression with appropriate examples, and (4) finally fully repeating the main points. The PREP method involves the following four steps:
- Point (Conclusion first): сlearly state your views and position first.
- Reason: provide a reason or argument in support of your view.
- Examples: reinforce your reasons with specific examples to make them more persuasive.
- Point (Conclusion again): emphasize the main points of view one last time to ensure that the information is conveyed.
The PREP method helps maximize the impression of essential points to the listener by clarifying the subject at the beginning and reemphasizing important information in the conclusion.
Leave Space for Questions
There are other techniques for attracting and holding the audience’s attention. Make a positive statement, then ask a question that would require a show of hands to answer. You could create a short Q&A & session! For example, ask how many of those present have their own business or how long they have been involved in biohacking. Show them what you want them to do by raising your hand! Once a certain number of people have raised their hands, you can engage them in a short conversation, so ask them something else or find out a specific person’s opinion, and then move on to your topic.
Or ask those present to turn to their neighbors and discuss a specific topic. For example, what they want from their profession, or what knowledge they plan to gain from this event.
Remember that almost all techniques for attracting and retaining the audience’s attention — and this one in particular — only work when you feel like a leader.
Listeners will be willing to do what you say as long as you feel and act confident.
Be an Active Listener
At the same time, it is important not only to listen, but also to hear! This perfectly complements the point about audience interaction. It is also important to respond to how people around you react to your words, gestures, ideas, and interactions. If you only do what you have decided in advance, without analyzing what is happening and reading people’s reactions, everything will be ruined. Be prepared to improvise and make spontaneous decisions. By hearing the audience’s wishes or responses in time, you can orient yourself and continue your performance in the right direction.
Preparation for Better Communication
Strong communication isn’t just a talent — it’s a trainable skill. With a biohacking mindset, you can optimize how clearly, confidently, and effectively you express ideas by practicing a few intentional habits and communication techniques.
Read to Improve Vocabulary
Reading high-quality nonfiction, psychology, and well-written journalism expands your vocabulary and sharpens your ability to choose precise words. The broader your language range, the easier it becomes to explain complex ideas simply.
Write to Express and Structure Thoughts
Writing forces clarity. Journaling, outlining ideas, or summarizing what you’ve learned helps organize thoughts, improve logical flow, and reduce mental noise before speaking.
Create an Elevator Speech
A short, clear explanation of who you are and what you do trains your brain to communicate better and have a strong focus. This practice improves confidence, conciseness, and adaptability in real conversations.
Record Yourself
Listening to your own voice reveals pacing, tone, filler words, and emotional cues you may not notice otherwise. It’s one of the fastest ways to fine-tune verbal delivery.
Books for Improving Communication Skills
A few well-chosen books can significantly accelerate progress by offering proven frameworks, practical exercises, and insights into human behavior and influence.
- Crucial Conversations: Tools for Talking When Stakes Are High by Kerry Patterson, Joseph Grenny, Ron McMillan & Al Switzler — This practical guide teaches how to handle tough conversations where emotions run strong, and outcomes matter.

To sum up
Nonverbal expressions of emotion are a vital part of public speaking. Facial expressions, body position, gestures, and movements can say a lot about us. Openness and friendliness are effective ways to work with listeners, as these emotions are always read.
Good articulation demonstrates respect for the listener, making the speech easier to understand and saving the listener’s mental resources. Clear speech can convey confidence and competence, while poor articulation can create a negative impression. By practicing methods of effective communication to improve your articulation, start new communication habits and seek professional help, you can become a more confident communicator and enjoy the benefits of clear and interesting speech.
