Amazon Transcribe streaming adds support for Japanese, Korean, and Brazilian Portuguese

Amazon Transcribe is an automatic speech recognition (ASR) service that makes it easy to add speech-to-text capabilities to your applications. Today, we’re excited to launch Japanese, Korean, and Brazilian Portuguese language support for Amazon Transcribe streaming. To deliver streaming transcriptions with low latency for these languages, we’re also announcing availability of Amazon Transcribe streaming in the Asia Pacific (Seoul), Asia Pacific (Tokyo), and South America (São Paulo) Regions.

Amazon Transcribe added support for Italian and German languages earlier in November 2020, and this launch continues to expand the service’s streaming footprint. Now you can automatically generate live streaming transcriptions for a diverse set of use cases within your contact centers and media production workflows.
