# Pre-Call Prompts: Spoken Voice Configuration

> Add a voice prompt before a call connects, using either an automated text-to-speech prompt or a pre-recorded audio file.

You can set up Invoca to play a spoken voice prompt to a caller before they connect to your destination. As part of a call treatment, you can create these prompts using either a pre-recorded file or an automated prompt through your account's text-to-speech engine.

## Setting up a voice prompt

1. In your call treatment, add any node and check **Play prompt first**, if available.
2. For an automated text-to-speech prompt, use the Prompt Voice menu to choose a voice and accent, then enter the text you want spoken in the prompt text box. Press the play button to preview it.
   * You can include punctuation — question marks, exclamation points, periods, commas, and ellipses — to change intonation or add pauses.
   * If a word is mispronounced, try spelling it phonetically instead.
3. For a pre-recorded prompt, click **Add prompt recording** below the prompt text box. Upload a file from your computer, or click **Select an existing recording** to reuse a recording already in your account.
   * Invoca accepts WAV, AIFF, AIF, MP2, MP3, and AMR audio formats.
   * Include a script of your recording where prompted, for better accessibility and error prevention.

See "Call Treatments & IVR" for more on building the rest of your call treatment.
