The Voice Prompt Settings can be found in the application Options under the "Prompts" tab. This tab displays a list of all the voice prompts that are used by Axon for various interactive features like the internal voicemail system. From this list you can listen to or change any of the voice prompts.

To change a prompt, select the prompt and click on the 'Change...' button. This will pop up a menu with options that you can use to change the prompt. Here you can choose to record a new prompt, load an existing wav or mp3 file, synthesize text to speech, edit the existing prompt (using WavePad), or restore the default file.
