What this topic is really about
Amazon Bedrock Knowledge Bases automates Retrieval-Augmented Generation (RAG) by connecting foundation models to internal data sources for more accurate, context-aware responses. It does not train new foundation models from scratch (Option A), which is a highly resource-intensive process typically handled by SageMaker or pre-training pipelines.
Amazon Transcribe is an AWS service designed specifically to convert spoken audio files into accurate text transcripts using automatic speech recognition technology. In contrast, converting text back into lifelike speech is handled by Amazon Polly, which makes the text-to-speech option incorrect.
