How to help the bot pronounce phone numbers correctly

In some languages the bot can change the pronunciation of phone numbers to a basic number. To make sure a phone number is pronounced correctly, you can use Speech markdown (SSML). See the voices overview in the developer documentation to make sure your chosen voice supports SSML.

In the flow you can add speech markdown in brackets to a phone number to make sure the bot interprets it correctly: [phone]

(variable)[phone] or ([phone])[phone]
