Speaker-labeled transcription with WhisperX on SageMaker AI
Amazon Web Services 2 weeks ago 22 ● 2 sources
AWS published a guide for deploying the WhisperX speech-to-text deep learning container on Amazon SageMaker AI to produce transcripts with word-level timestamps and speaker labels. The real-time endpoint must return within a 60-second response cap, while long audio should use the asynchronous endpoint. This changes transcription outputs and deployment workflow by adding per-word alignment and diarization labels and by routing requests through either synchronous or S3-backed async inference on SageMaker.
