Here at Speechmatics, audio is the lifeblood of everything we do, from training our models right through to crafting effective demos of our technology. One of the best examples of this is our Portal translation demo, which allows the user to see their speech translated into a number of languages in realtime. However, accessing media devices through the browser isn't straightforward. Browsers require the user to explicitly permit access to the media device, and to make things even more complicated, each browser engine has its own quirks that have to be handled. In this article, I'll walk through how we were able to provide a consistent and straightforward microphone access experience for our demos across all the major browsers and devices.
