Setup menu prompt
The choice element (Main Menu element in the call flow diagram) usually requires audio message to prompt a caller to press certain keys. You can use three types of prompts:
1. Pre-recorded audio files
The format of the audio file needs to be: PCM 8KHz, 16 bit, mono. This format is the global standard for telephone communications. For more information about audio, please see Audio Quality and Recording FAQ.
2. Text using text-to-speech
You need Voicent Text-to-Speech PlugIn for automatic voice generation. You can use any TTS engine/voice with the PlugIn.
3. Variable: either audio file or text
The variables are dynamic generated items, such as a caller input of credit card number. These items are usually collected during run time.
To set the prompt for an element, right mouse click on an element, then choose Properties... from the popup menu. Click the Prompt tab, then click the New... button.
