Question
You are designing an AI solution to monitor meetings. The AI model should be able to indicate when people are happy or sad using their facial expressions. Which cognitive service should you use for the solution?
A. Text Analytics.
B. Face API.
C. Computer Vision.
D. Speech-to-text.
Answer
B. Face API.
Explanation
The Azure Face API is a cognitive service that provides algorithms for detecting, recognizing, and analyzing human faces in images. One of its key capabilities is detecting facial expressions and inferring emotional states like happiness, sadness, anger, contempt, fear, disgust, surprise and neutral.
By contrast:
- Text Analytics API extracts information from text, such as sentiment, key phrases, named entities, and language. It cannot analyze facial expressions in images/videos.
- Computer Vision API provides algorithms for processing images and returning information about visual features, but it does not specialize in human face detection and emotion recognition like the Face API does.
- Speech-to-text converts spoken audio to text. It does not analyze facial expressions or emotions.
Therefore, when designing an AI solution to monitor meetings and determine when people are happy or sad based on their facial expressions, the Azure Face API is the best fit among the cognitive services listed. You would use its facial expression recognition capabilities to infer emotional states from images or video frames of meeting participants’ faces.
The Face API can analyze facial expressions to detect emotions like happiness or sadness, which is suitable for your AI solution to monitor meetings based on facial expressions.
