Which service automatically converts spoken language in audio into written text?

• A. AWS CloudTrail
• B. Amazon Transcribe
• C. Amazon Translate
• D. Amazon Rekognition

Answer: (B)

Converting spoken language in audio into written text is the job of automatic speech recognition. In AWS, that capability is provided by Amazon Transcribe. It processes audio input and returns a text transcript, supporting features like real-time streaming or batch transcription, punctuation, and even speaker labeling. The other services serve different purposes: CloudTrail records API activity for governance and auditing, Translate turns text from one language into another, and Rekognition analyzes images and videos for content such as objects or faces. So for turning spoken words into written text, Amazon Transcribe is the appropriate choice. If you later need to translate the transcript into another language, you could apply Amazon Translate to the resulting text.
