The play prompt block allows you to play a message (Text-To-Speech or an audio file) over the ongoing call. During the entire time the message is playing, all input from the caller will be ignored, meaning that the caller has to wait for the entire message to finish before the flow continues.

📘

TTS character limit

When using regular Text-To-Speech (TTS), the prompt is limited to 500 characters. If your prompt exceeds 500 characters, only the first 500 characters will be played. It's important to keep within this limit to ensure that your entire message is conveyed effectively during the call.

🚧

SSML character limit

When using SSML (Speech Synthesis Markup Language), there is a limit of 1000 characters. If your SSML prompt exceeds this limit, the prompt will not be played. This is because truncating the prompt to fit within the 1000-character limit could potentially break the SSML syntax and render the prompt unusable.
