In the Children’s Online Privacy Protection Act (COPPA) section, select No.For Runtime role, select Create a role with basic Amazon Lex permissions.For Description, enter an optional description.On the Amazon Lex console, choose Switch to the new Lex V2 console.For this post, we use the newer V2 console. When the CloudFormation stack is complete, we’re ready to create the Amazon Lex bot. Note the name of the Lambda function because we reference it later when creating the Amazon Lex bot. When it’s complete, you can go to the Resources tab to check out the Lambda function and DynamoDB table created. The AWS CloudFormation stack takes a few minutes to complete. You must deploy the DynamoDB table and Lambda function directly by choosing Launch Stack. Download all the files, including the PocketSphinx model files downloaded from their repo. You can find all the files of our custom voice assistant solution on our GitHub repo. Now you’re ready to create the components needed for this solution. Amazon Lex sends back a voice message, and we use Amazon Polly, a service that turns text into lifelike speech, to create a consistent experience. ![]() Sensor types include blood pressure, blood glucose, body temperature, respiratory rate, and heart rate. The sensor data is generated by another Python script, generate_data.py, which you also run on your computer. After the wake word is recognized, the voice assistant starts recording what you say and sends the audio to Amazon Lex, where it uses an AWS Lambda function to retrieve dummy patient data stored in Amazon DynamoDB. In our solution, we first interface with a voice assistant script that runs on your computer. The following architecture diagram presents the high-level overview of our solution. Custom voice assistant solution architecture With our easy-to-set-up and managed services, developers and innovators can hit the ground running and start developing the devices of the future. In this post, you learn how to create a custom voice assistant using PocketSphinx and Amazon Lex. ![]() However, most devices are limited, so developers must often build their own customized versions.Īs Solutions Architects working in the healthcare industry, we see a growing trend towards the adoption of voice assistants in hospitals and patient rooms. Today, voice assistants are becoming more available as natural language processing models advance, errors decrease, and development becomes more accessible for the average developer. They can be a powerful tool to help doctors save time, reduce stress, and spend more time focusing on the patient versus the administrative requirements of clinical documentation. Voice assistants are now starting to automate the vital yet manual parts of patient care. Voice assistants as a solution to physician burnout We also walk through creating a custom voice assistant using PocketSphinx and Amazon Lex. In this post, you learn the importance of voice assistants and how they can automate administrative tasks for doctors. In addition, it can lead to higher turnover, reduced productivity, and costly medical errors, affecting people’s lives and health. Physician burnout is one of the leading factors that lead to depression, fatigue, and stress for doctors during their careers. To maintain these records, physicians often spend multiple hours each day to manually enter data into the EHR system, resulting in lower productivity and increased burnout. That record is stored in the hospital electronic health record (EHR) system, a database that contains the records of every patient in the hospital. Physicians and clinicians must keep a detailed medical record for each patient. Although patient interaction and diagnosis are critical aspects of a physician’s job, administrative tasks are equally taxing and time-consuming. ![]() For the past few decades, physician burnout has been a challenge in the healthcare industry.
