The effectiveness of subliminals that claim to change your voice and appearance is a topic of debate and lacks scientific consensus. Subliminals are audio or visual messages that are designed to bypass your conscious awareness and target your subconscious mind. Proponents of subliminals believe that by repeatedly listening to or watching these messages, you can influence your thoughts, behaviors, and even physical characteristics.
However, it's important to approach these claims with caution. While there is some evidence to suggest that subliminal stimuli can have a subtle impact on behavior under specific conditions, there is limited scientific research specifically addressing the efficacy of subliminals for changing physical characteristics like voice or appearance.
It's worth noting that any perceived changes attributed to subliminals could also be attributed to a placebo effect or the result of other factors such as confidence-building, self-improvement practices, or simply the passage of time.
If you're interested in making changes to your voice or appearance, it is generally more reliable and effective to seek professional guidance from experts in those fields. For example, if you want to improve your voice, you could consult a voice coach or speech therapist. If you're concerned about your appearance, a dermatologist, cosmetic professional, or personal stylist may be able to provide appropriate guidance and solutions.
