Output definition

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

2.1 TEMPER

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:
