What is speech analytics?

Chevron down icon

Speech analytics is the process of analyzing voice recordings to extract insights. It identifies patterns, emotions, keywords, and sentiments in customer service calls, helping businesses improve service, monitor compliance, and understand customer needs. By analyzing how and what customers are saying, businesses can make informed decisions to improve their products, services, and customer interactions.

Why use speech analytics?

Speech analytics is used to gain customer insights, improve service quality, ensure compliance, enhance employee training, identify trends, resolve issues quickly, and support data-driven business decisions.

Is NLP and speech analytics the same?

Chevron down icon

No, NLP (Natural Language Processing) and speech analytics are not the same, although they are related fields. NLP (Natural Language Processing) is an AI field focused on enabling computers to understand human language, while speech analytics is an application of NLP that analyzes spoken language, particularly in business settings, for insights and trends.

Is NLP and speech recognition the same?

Chevron down icon

No, NLP (Natural Language Processing) and speech recognition are not the same. NLP deals with understanding and interpreting human language by computers, while speech recognition focuses specifically on converting spoken words into text.

Is using speech analytics in a call center more beneficial compared to the traditional methods?

Chevron down icon

Yes, using speech analytics in a call center is more beneficial compared to traditional methods due to several reasons:

  • Enhanced Customer Insights: Speech analytics can provide deeper insights into customer needs, preferences, and pain points by analyzing call content.
  • Quality Assurance: It enables more comprehensive and efficient monitoring of call quality and agent performance compared to manual review processes.
  • Operational Efficiency: Automatic analysis of calls saves time and resources, allowing for quick identification and resolution of issues.
  • Data-Driven Decisions: The ability to analyze large volumes of calls provides a robust data set for informed decision-making and strategy development.
  • Improved Compliance: Speech analytics can help in ensuring adherence to regulations and standards by identifying non-compliant practices.
  • Employee Training and Development: Insights from call analyses can be used for targeted training and feedback for customer service representatives.
  • Trend Identification: It helps in spotting trends and recurring issues in customer interactions, leading to proactive problem solving.

Traditional call center methods, prior to speech analytics, included random call sampling, live call monitoring by supervisors, evaluations using standardized checklists, post-call customer surveys, agent self-assessments, and analysis based on basic call metrics like duration and volume. These methods were very time-consuming and less comprehensive compared to modern speech analytics.
