====== Voice of Customers (VOC) ====== Based on natural language processing, theme modeling and sentiment analysis, the voice of the customer (VOC) analyzes the messages of customers and agents, generates the sentiment indexes of customers and agents and frequent keywords, and allows admins to track the messages and conversations that correspond to these keywords. VOC enables the customer service management team to understand the most frequently mentioned themes and keywords in the historical conversations and the corresponding sentimental temperatures, to determine the hot issues in the service. VOC is a value-added service. To activate it, please provide the tenant ID and contact Hyphenate.
