+         Understanding human emotions is critical for businesses that interact with customers, employees, or users through text, speech, or images.
+         Subjectivity of Emotions: Emotions can be complex, overlapping, and vary based on individual perceptions.
+* Data Limitations: Labeled emotional datasets are often limited or imbalanced.
+* Real-time Processing Needs: Businesses require fast, scalable solutions for handling large volumes of data.
+* Multimodal Complexity: Emotions can be expressed through text, speech, or facial expressions, requiring different ML models.
+* Privacy & Ethical Concerns: Emotion analysis can raise ethical and legal issues related to data privacy.""")
