Serverless speech recognition with WebAssembly

In plain words

Patter.io is a speech recognition service built with WebAssembly that operates without requiring traditional servers. Launched in 2017, it converts spoken audio into text locally in the browser. The product is designed for developers and users who need speech-to-text functionality with reduced server dependency. Its serverless architecture and WebAssembly implementation allow processing to happen on the client side, potentially offering faster response times and improved privacy compared to cloud-based alternatives.
