Why Voice

When it comes to emotions understanding and communication, our tone of voice, or the way we pronounce our words and sentences, communicate a great deal of information and insights – sometimes more than the spoken words themselves. Therefore, understanding emotions through our voice – not just the words but the tone of voice as well – becomes an essential element in making AI-driven Personal Assistant more emotionally aware as well as more in tune to the customers' needs and expectations. Here are a few ways it can play a role with your Virtual Private Assistant.

Adding Conversation: Humanizing the interaction between the person and the device

Recommendations and Predictions: Content suggestions, e.g. music, restaurants or TV shows, via a more intelligent device that factors in the mood of the speaker.

Brand Perception: Immediate customer feedback on packaging, products, services and sellers. A post sale communication with the consumer is indispensable for full satisfaction, sustained engagement and recommendations.

Digital Health and Wellness: Further down the road – ongoing monitoring of vocal biomarkers that indicate certain health conditions to promote behavioral changes toward a healthier style
