Do Voice Surveys support free-form text input?

Yes. Voice Surveys support free-form text input through Free Text survey questions. When the configured language supports speech recognition, customers can provide open-ended responses by speaking, which are captured using speech-to-text. Free-form text responses are limited to 500 characters. If speech recognition is not supported for the configured language, free-form spoken input is not available and survey questions must rely on DTMF-based responses instead. For more information, see: Add questions to a customer survey form, and Ask Survey Question action.
