How Amazon Transcribe works
Amazon Transcribe uses machine learning models to convert speech to text.
In addition to the transcribed text, transcripts contains data about the transcribed content, including confidence scores and timestamps for each word or punctuation mark. To see an output example, refer to the Data input and output section. For a complete list of features that you can apply to your transcription, refer to the feature summary.
Transcription methods can be separated into two main categories:
-
Batch transcription jobs: Transcribe media files that have been uploaded into an Amazon S3 bucket. You can create batch transcriptions using the AWS CLI, AWS Management Console, and various AWS SDKs.
-
Streaming transcriptions: Transcribe media streams in real time. You can create streaming transcriptions using the AWS Management Console, HTTP/2, WebSockets, and various AWS SDKs.
Note that feature and language support differs for batch and streaming transcriptions. For more information, refer to Amazon Transcribe features and Supported languages.
