Transcribing numbers and punctuation
Amazon Transcribe treats numbers differently depending on the language and the context in which they're used. For most languages, numbers are transcribed into their word forms. English and German dialects support digit transcription, as outlined in Rules for transcribing numbers in English and Rules for transcribing numbers in German.
Amazon Transcribe automatically adds punctuation to all supported languages, and capitalizes words appropriately for languages that use case distinction in their writing systems.
