2025 Best In KLAS Ambient Speech

Executive Summary: With the primary goal of improving clinician well-being, St. Luke’s Health System set out to invest in a technology solution that would (1) alleviate burnout and improve documentation efficiency and (2) deliver a financial ROI within two years. To do so, they partnered with Ambience Healthcare and implemented Ambience—an AI-powered ambient platform that automatically generates clinical documentation and associated diagnostic and billing codes directly in the providers’ natural workflow. By eliminating manual note-taking and enhancing coding accuracy, St. Luke’s has realized substantial returns, including measurable financial gains and reduced clinician burnout.

Over the past year, the adoption of ambient speech technology—solutions that use healthcare-specific language models to capture patient-provider encounters and contextualize them into structured notes—has surged exponentially (see below). Additionally, this technology has rapidly evolved in recent months, further enhancing provider documentation and even expanding beyond note creation. More and more, healthcare leaders are looking to ambient speech solutions to improve clinician satisfaction, documentation quality, and efficiency. This report—KLAS’ first to compare vendor performance in this high-performing space—examines how well vendors drive customer satisfaction and facilitate EHR integration; market insights around adoption and outcomes are also shared.

Ambient Speech 2024

25 October 24 | Braden Taylor and Mac Boyter

With the rapid expansion of generative AI, ambient speech technology has been top of mind for healthcare organizations as they seek increased efficiency, improved note quality, and improved provider well-being. While ambient speech vendors previously had to provide QA specialists to review created notes, generative AI has enabled ambient speech technology to become more fully automated and do more than just transcribe medical notes. Many organizations are currently making or have made ambient speech purchase decisions in the last year; while some are beginning to move past the pilot stage, broad adoption of this technology is not yet common. To help healthcare organizations understand why certain vendors are being considered and selected, this report—KLAS’ first to focus on only ambient speech technology—examines feedback from 80 organizations that are making or have recently made decisions between January 2024 and August 2024. (This report does not represent a comprehensive census or win/loss market share study.)

Healthcare organizations continue to evaluate ambient speech AI solutions with the goal of improving clinician well-being, increasing operational efficiencies, and enhancing care quality. Ambience Healthcare offers a voice-enabled, fully automated generative AI solution that is used across various care settings to create clinical documentation and assist with workflow tasks such as code suggestions and pre-charting. This report examines early customer experiences and satisfaction with the product.
