CHAPTER 1 INTRODUCTION
The Emotion AI engine (API V5) of Beyond Verbal takes raw voice input and analyzes it for mood and emotional state.
- The Emotion AI engine (API V5) measures the speaker's current emotional state. It requires at least 10 seconds of authentic speech to render the initial emotional analysis. All subsequent analyses are rendered every 5 seconds. For more information, please refer to our recording guidelines.
- The outputs are distributed into several emotional parameters, as listed below within this document.
CHAPTER 2 EMOTION PARAMETERS
The Emotion AI engine measures the speaker's emotional state during the analyzed voice section into three separate emotion parameters: Temper, Valence, and Arousal.
Temper reflects the speaker’s emotional state. It includes three main categories: depressive, embracive and aggressive.
The Temper output is divided into two distinct measurements:
- Value of Temper is represented by a number on a continuous scale ranging from 1 to 100.
- Group of Temper, which consist of three distinct groups: Low, Med, High.
2.1.1 High Temper
High temper occurs when the speaker experiences and expresses aggressive emotions oriented outwards, such as active resistance, anger, hatred, hostility, aggressiveness, forceful commandment and/or arrogance.
2.1.2 Medium Temper
Medium temper occurs when the speaker experiences and expresses the following two types of emotions:
- Embracive “positive” emotions, communicated in a warm and friendly manner, such as empathy, acceptance, friendliness, closeness, kindness, affection, love, calmness, and motivation.
- Self-controlled “neutral” emotions communicated in a “matter-of- fact” intonation.
2.1.1 Low Temper
Low temper occurs when the speaker experiences and expresses negative emotions in an inhibited fashion, such as sadness, pain, suffering, insult, inferiority, self-blame, self-criticism, regret, fear, anxiety and concern (can also be interpreted as fatigued). It is as though the speaker is waning, growing smaller, or pulling back.
Valence refers to the level of negativityorpositivity It ranges from negative emotional state to positive emotional state.
The Valence output is divided into two distinct measurements:
- Value of Valence is represented by a number on a continuous scale ranging from 1 to 100.
- Group of Valence, which consist of three distinct groups: Negative, Neutral and Positive.
2.2.1 Negative Valence
The speaker’s voice conveys emotional pain and weakness or aggressive and antagonistic emotions.
2.2.2 Neutral Valence
The speaker’s voice conveys no preference and comes across as self-control or neutral.
2.2.3 Positive Valence
The speaker’s voice conveys positive emotions, such as happiness, warmth, enthusiasm or calmness.
Arousal is an output that measures the speaker’s level of energy, ranging from tranquility, boredom or sleepiness to alertness or excitement. Arousal can also correspond to similar concepts such as involvement and stimulation.
The Arousal output is divided into two distinct measurements:
- Value of Arousal is represented by a number on a continuous scale ranging from 1 to 100.
- Group of Arousal, which consist of three distinct groups: Low, Neutral and High.
2.3.1 Low Arousal
The speaker’s voice conveys low levels of alertness and can be registered in cases of sadness, comfort, relief, or sleepiness.
2.3.2 Neutral Arousal
The speaker’s voice conveys a medium level of alertness and can be registered in cases of normal conduct, indifference, or self-control.
2.3.3 High Arousal
The speaker’s voice conveys a high level of alertness such as excitement, surprise, passionate communication, extreme happiness, or anger.
CHAPTER 3 EMOTION GROUPS
