ThisGen.ai is revolutionizing the training of 911 dispatchers by using AI-generated voices to create realistic emergency call simulations, which are crucial for preparing new dispatchers for the diverse challenges they will encounter on the job. Supported by an ElevenLabs Grant, the platform has developed lifelike caller voices representing various ages, genders, accents, and emotions, which reflect the real challenges of emergency response. The platform addresses the high vacancy rates in U.S. dispatch centers, enabling quicker training through its realistic simulations, which have been adopted by over a hundred dispatch centers in just a few months. ThisGen's simulations are not only valuable for new hires but also for on-the-job and remedial training, ensuring teams are prepared for high-stakes, infrequent situations. The company is further enhancing the platform with features like multi-participant calls and background noise to increase training immersion, effectively blending AI with practical needs to transform emergency response training.
