Coloured Lines offers the advanced Call Journey speech analytics platform (“Workbench”) and their underlying EVS (“Emotive Voice Streams “) engine.  EVS is a state of the art, cloud-based Conversation Analytics Engine. It uses Artificial Intelligence to understand long conversations between multiple speakers.

This platform will permit you to ingest call recordings from your contact centre / telephony platforms and provide instantaneous, customised and predictive analysis on the content of those calls.  The analysis will lead to better customer outcomes, more effective agent performance and a reduction in risk to the business.

Within every single connection is a complex and invaluable collection of data, which when unlocked can unleash a wealth of insights about your customers and staff. With this information you can do a lot. You can listen better and understand both sides of a conversation, turning everyday interactions into valued relationships.
