# Custom Vocabulary

Custom Vocabulary in AWS Transcribe allows you to define domain-specific terms, unique product names, or uncommon words to improve the accuracy of speech-to-text transcriptions. By creating and managing custom vocabularies, you can ensure that specialized terminology is recognized correctly during transcription jobs. This resource is part of the Transcribe service and is retrieved through the GetVocabularyResponse API.
