AllGoodSpeakers ApS: The rhetoric research company
What is the shortest path between two points? A straight line, i.e. a direct link without waypoints and detours. So what is the fastest and most effective way to offer up-to-date rhetorical training? To do own research and directly implement its results in products and services. This is what we do.
AllGoodSpeakers does not simply take research into account. AllGoodSpeakers is itself a research company! We continuously conduct top-notch experimental and instrumental speech-production and speech-perception research. We can rely on one of the world's largest oral-presentation databases, and each new dataset makes PISCA and Acoustic Voice Profiling® a little smarter and more precise.
And this is only the first step. In combination with the charismatic voice of a speaker, we also do research on attire, the sound of shoe heels, foreign-language accents, the ideal microphone, and a lot of other things that help you improve your personal charismatic impact on people. In the near future, PICSA will be able to measure how tall you sound acoustically! The taller a person the stronger is his/her charismatic impact. We will be the first to teach you how to sound not just better but also taller. Imagine the advantage that this ability gives you over others, for example, on the phone or in video conferences!
Research conducted by AllGoodSpeakers also helped confirming or busting some common myths about charismatic speech. Is a clear pronunciation really beneficial for your charismatic impact? Yes, that's right! Does belly breathing help in sounding more charismatic? No, that's just a myth! Do more charismatic speakers have lower voices? No, that's a myth as well. Rather, the opposite is true! Have a look at this scientific article here. And if you want to learn what really matters for charismatic leadership and presentations, book a course with us!
Our goal: We define the state-of-the-art in rhetorical charisma training!
