Transcribing numbers and punctuation
Amazon Transcribe automatically adds punctuation to all the languages that it supports. It also capitalizes words appropriately for languages that use case distinction in their writing systems. For example, the spoken number "one thousand two hundred fortytwo" is transcribed as "1242" in supported languages. For all other languages, numbers are transcribed into their word forms.
For a list of supported languages, see Supported languages and languagespecific features.
