About a month ago I had an idea while riding the bus to school: what if I could listen to my handwritten notes instead of reading them? I wanted a simple, cost-effective solution, and since I usually work with AWS, I decided to set everything up on that platform.
The architecture I chose is serverless, inexpensive, and easy to deploy. I use Amazon Textract to extract text from images, Amazon Polly to convert that text into natural-sounding speech, AWS Lambda and API Gateway for serverless logic and routing, and Amazon S3 to store images and audio files. All of this is orchestrated with Terraform to ensure infrastructure as code and reproducible deployments.
The basic application flow is simple: the user uploads an image to the API Gateway endpoint, the image is saved to S3, Textract extracts the text, Polly converts the text to MP3, the MP3 is saved to another S3 bucket, and a pre-signed URL is generated so the user can listen to or download the file. I tested it with photos of my class notes and got an audio file within seconds.
I chose these technologies for their effectiveness and cost. Amazon Textract handles handwritten or printed text, Amazon Polly offers natural voices and customization options, AWS Lambda eliminates the need to manage servers, and API Gateway securely exposes the service. S3 acts as durable, low-cost storage. With Terraform I automate buckets, Lambda functions, IAM permissions, and the API Gateway endpoint, and deployment is reduced to running terraform init and terraform apply.
The result was a practical tool for students: I can listen to notes while walking, traveling, or cooking, paying only for what I consume thanks to the serverless model. Polly can sound a bit robotic at times, but it is perfectly usable for this use case.

This project also serves as an example of how to integrate managed services to accelerate development time and reduce operational costs. For companies interested in automating document conversion processes, accessibility, or audio content generation, combining Textract and Polly with Lambda and S3 is a solid option. At Q2BSTUDIO we can adapt this solution as custom software for your organization, integrating AI agents, data pipelines compatible with Power BI, and cybersecurity controls according to regulations and best practices.
Some key benefits of this approach: reduced reading time, greater accessibility for users with visual impairments, the ability to create podcasts from notes or automatic summaries, and controlled costs thanks to the serverless model. Additionally, implementing infrastructure as code with Terraform provides traceability, reproducibility, and ease of replicating environments on AWS or Azure depending on the chosen cloud strategy.
If you are interested in a demo or developing a customized version, Q2BSTUDIO offers consulting for AI projects, custom software development, integration with AWS and Azure cloud services, and deployment of business intelligence solutions with Power BI. We can design AI agents that automate content organization, tagging, and document reading tasks, always reinforcing the cybersecurity of the solution.
In summary, converting notes into audio using Textract, Polly, Lambda, API Gateway, and S3 is a practical and cost-effective solution. Terraform automates the entire infrastructure lifecycle. If you are looking to take this idea to production, enhance it with advanced artificial intelligence, or integrate the solution into a corporate ecosystem, at Q2BSTUDIO we design custom software and custom applications that include AI for businesses, AI agents, business intelligence services, and cybersecurity and cloud strategies to ensure a secure and efficient deployment.
