Why Should You Use this Voice App?

Lifestyle: Getting to Know Yourself Better

    (1) Get involved and learn more about the complex interplay between body and mind under high levels of stress caused, for example, by modern work conditions or by tight schedules and frequent examinations in college.

    (2) Learn more about your affects, the evolutionarily very old processes deep inside your body. Affects such as aggression, fear, anger, happiness, sadness, grief, or love, can be triggered through internal and external events, and are often accompanied by bodily reactions, such as sweat, rapidly increased blood pressure, increased heart rate, dizziness, and others.

    (3) Learn how regular voice recordings can improve your coping behavior under stress, so that you feel pretty comfortable, for example, when speaking in public — such that mean vocal pitch doesn’t go up by a halftone or so.

Subjects at Risk of Mood Disturbances

    (4) Get involved and learn how low mood reduces the dynamic expressiveness of your voice and how your voice sounds when it regains energy, vivacity and spiritedness.

    (5) Find out how helpful it is to go for a 20-minute walk, to ride a bicycle, or to do sports.

    (6) And best of all: getting involved on a routine basis is a great remedy to better cope with the ups and downs of real life.
