This blog post is a roundup of voice emotion analytics companies. It is the first in a series that aim to provide a good overview of the voice technology landscape as it stands. Through a combination of online searches, industry reports and face-to-face conversations, I’ve assembled a long list of companies in the voice space, and divided these into categories based on their apparent primary function.

The first of these categories is voice emotion analytics. These are companies that can process an audio file containing human speech, extract the paralinguistic features and interpret these as human emotions, then provide an analysis report or other service based on this information.


Beyond Verbal

Beyond Verbal was founded in 2012 in Tel Aviv, Israel by Yuval Mor. Their patented voice emotion analytics technology extracts various acoustic features from a speaker’s voice, in real time, giving insights on personal health condition, wellbeing and emotional understanding. The technology does not analyze the linguistic context or content of conversations, nor does it record a speaker’s statements. It detects changes in vocal range that indicate things like anger, or anxiety, or happiness, or satisfaction, and cover nuances in mood, attitude, and decision-making characteristics.

Beyond Verbal’s voice emotion analysis is used in various use cases by clients in a range industries. These include HMOs, life insurance and pharma companies, as well as call centres, robotics and wearable manufacturers, and research institutions. An example use case would be to help customer services representatives improve their own performance, by monitoring the call audio in real-time. An alert can be sent to the agent if they start to lose his/her temper with the customer on the phone, making them aware of their change in mood, and affording them the opportunity to correct their tone.

The technology is offered as a API-style cloud-based licensed service that can be integrated into bigger projects. It measures:

  • Valence – a variable which ranges from negativity to positivity. When listening to a person talk, it is possible to understand how “positive” or “negative” the person feels about the subject, object or event under discussion.
  • Arousal – a variable that ranges from tranquility/boredom to alertness/excitement. It corresponds to similar concepts such as level of activation and stimulation.
  • Temper – an emotional measure that covers a speaker’s entire mood range. Low temper describes depressive and gloomy moods. Medium temper describes friendly, warm and embracive moods. High temper values describe confrontational, domineering and aggressive moods.
  • Mood groups – an indicator of speaker’s emotional state during the analyzed voice segment. The API produces a total of 11 mood groups which range from anger, loneliness and self-control to happiness and excitement.
  • Emotion combinations – A combination of various basic emotions, as expressed by the users voice during an analyzed voice section.

“We envision a world in which personal devices understand our emotions and wellbeing, enabling us to become more in tune with ourselves and the messages we communicate to our peers. Understanding emotions can assist us in finding new friends, unlocking new experiences and ultimately, helping us understand better what makes us truly happy.”
Yuval Mor, CEO
