Emotion Detection

Press on pictures to see analysis





VoiceSense emotion detection analytic engine provides real-time indications of the four basic emotions:
happiness, anger, sadness and contentment.
The analysis consists of two scales:
     Emotional excitement level - vertical scale
     Polarity (positive/negative) - horizontal scale
The combination of the two scales creates the four basic emotions:
     Happiness, enthusiasm – positive, high excitement
     Anger, frustration – negative, high excitement
     Sadness, disappointment – negative, low excitement
     Content, satisfaction – positive, low excitement

The analysis is fully language independent – it works well in different languages, including tonal languages.
The analysis is fully speaker independent – it doesn't require learning/training of the specific speaker voice.
The analysis has a short response time of 5-10 seconds and it reflects emotional changes in the speech over the last 30 seconds.  
The analysis engine provides also statistical summaries of emotion distribution over longer time periods.
