By processing this data with machine learning algorithms, speech analytics can reveal patterns, trends, and insights that can be used to improve various aspects of call center performance, such as:

  • Customer service quality
  • Operational efficiency
  • Sales and marketing effectiveness
  • Risk and compliance management

How does Speech Analytics work?

The process of speech analytics involves several steps, including:

  • Recording and transcribing the spoken conversation
  • Analyzing the text for relevant data points, such as keywords and sentiment
