Using Amazon Transcribe streaming with WebSocket Voila! No need to worry about cross-origin resource sharing (CORS) as there would be when using HTTP. It is also practical for cross-domain usage. WebSocket is suitable for long-lived connectivity whereby both the server and the client can transmit data over the same connection at the same time. The protocol was standardized by the IETF as RFC 6455 in 2011. WebSocket is a full-duplex communication protocol built over TCP. However, for reference on using HTTP/2, you can read our previous blog post and tech documentation. ![]() In this blog post, we assume that you are aware of our streaming transcription service running over HTTP/2, and focus on showing you how to use the real-time offering over WebSocket. WebSocket support makes streaming speech-to-text through Amazon Transcribe more accessible to a wider user base, especially for those who want to build browser or mobile-based applications. We are excited to share that we recently started supporting real-time transcriptions over the WebSocket protocol. This enabled users to pass a live audio stream to our service and, in return, receive text transcripts in real time. In November 2018, we added streaming transcriptions over HTTP/2 to Amazon Transcribe.

Amazon Transcribe can be used to transcribe customer service calls, to automate closed captioning and subtitling, and to generate metadata for media assets to create a fully searchable archive. Many of these providers use outdated technology that does not adapt well to different scenarios, like low-fidelity phone audio common in contact centers, which results in poor accuracy.Īmazon Transcribe uses a deep learning process called automatic speech recognition (ASR) to convert speech to text quickly and accurately. Historically, customers had to work with transcription providers that required them to sign expensive contracts and were hard to integrate into their technology stacks to accomplish this task. Therefore, recorded speech needs to be converted to text before it can be used in applications. Audio data is virtually impossible for computers to search and analyze.
