Improve customer service efficiency with AI-powered summarization using Amazon Transcribe Call Analytics

Machine Learning

In the fast-paced world of customer service, efficiency and accuracy are paramount. After each call, contact center agents often spend up to one-third of the total call time summarizing the conversation with the customer. Additionally, manual summarization can result in inconsistencies in style and level of detail due to different interpretations of note-taking guidelines. Not only does this post-contact work increase wait times for customers, but it can also put pressure on some agents to avoid note-taking altogether. Supervisors also often listen to call recordings and read transcripts to understand the key points of customer conversations when investigating customer issues or evaluating agent performance. It takes a lot of time. This can make it difficult to scale quality control within your contact center.

To address these issues, we launched a generative artificial intelligence (AI) call summarization feature in Amazon Transcribe Call Analytics. Transcribe Call Analytics is an AI-powered generative API that generates highly accurate call transcripts and extracts conversation insights to improve customer experience, agent productivity, and supervisor productivity. Powered by Amazon Bedrock, a fully managed service that provides high-performance foundation model (FM) choices through a single API, Transcribe Call Analytics' generative call summarization helps agents capture notes after each conversation. Generate call summaries that reduce the time you spend summarizing. . This reduces customer wait times and increases agent productivity. Generative call summaries also allow supervisors to gain quick insights into conversations without having to listen to the entire call recording or read the entire transcript.

Praphul Kumar, Chief Product Officer, SuccessKPI said:

“The Amazon Transcribe Call Analytics API's generative call summarization allows us to add generative AI capabilities to our platform more quickly. This feature automatically summarizes calls and eliminates the need for agents to write notes after a call. We look forward to bringing this valuable functionality into the hands of even more large enterprises.”

We previously published how you can use generated AI to improve agent productivity through automated call summarization. This new generative call summarization feature automatically integrates with multiple services and handles the necessary configuration, making it easy and seamless to get started and realize the benefits. There is no need to manually integrate with services or perform any additional configuration. Simply turn on this feature from the Amazon Transcribe console or using the start_call_analytics_job API. You can also generate post-call summaries through Amazon Transcribe Post Call Analytics Solution.
