Here is a note from the “Rain” agency:
Voice is a natural channel for conveying our emotions and feelings. However, voice technology is still trying to crack analyzing sentiment and how these data points can inform the creation of emotionally intelligent voice experiences and assistants. We have seen voice assistants like Amazon Alexa and Google Assistant expand their speaking styles to include different emotions in certain responses, reflecting more humanlike interactions.
However, monitoring emotions on the consumer side is still a nascent technology. Amazon has made some steps toward realizing this with its health and wellness wearable Halo, which tracks users’ tone through their voices to make them more aware of their communication styles. This week, we’ve seen a new update in emotion recognition with Spotify’s patent approval of technology that analyzes listeners’ moods. Even though the patent only points to a small amount of features and a targeted use case, we are beginning to see how voice technology might leverage sentiment to provide more relevant recommendations and experiences for consumers in many contexts.
