Voice
The Voice section is relevant when you’re using voice on a flow and the flow has steps of type Choice, Thumbnail or Hero, for which the system will not render the options by using voice. In this case you will provide the voice message as text, including all available options.
To see the Voice section, in the EditFlowStep page, click on the Voice section header. The section expands.
The Voice section contains many SpeakMessage fields as languages your bot has. The first field is for the voice message in the bot’s default language.
In the first SpeakMessage field, redact the voice message as text in the bot’s default message. In the subsequent SpeakMessage fields, enter the localized text of the redacted voice message in the bot’s additional languages (if any).
