A company has dual-channel recordings of customer service calls and needs an AWS managed service that can automatically convert the audio to text while identifying which words were spoken by the agent versus the caller. Which service should they use?
Amazon Lex
Amazon Polly
Amazon Comprehend
Amazon Transcribe
Amazon Transcribe performs automatic speech-to-text conversion for both real-time streams and stored audio files. It supports channel identification and speaker diarization, allowing transcripts to label who said what on each channel. Amazon Polly provides text-to-speech, Amazon Lex builds conversational chatbots, and Amazon Comprehend analyzes sentiment and entities in existing text-none of these services convert audio into labeled transcripts.
