Working With Voice Messages
Sending Voice Messages
When configuring campaigns, you can choose to send messages that will be left as voicemails for the recipients. These voice messages can be a message that you record, or a message that you type. Typed messages are converted to voicemails using text-to-speech technology.
The software delivers messages to the Delivery Address you configure. For messages to be delivered, the delivery phone number needs to include a country code. You can add additional phone number options to your contacts by editing the Contact Type from the Settings menu. Once a new phone number type is added, you can use the import feature from the Contacts view to populate phone numbers as needed.
Basic Tips for Writing Text-to-Speech
When sending voice messages, typed messages are converted to audio. In this scenario, consider the following rules:
- When translating numbers, '12345' is spoken as "twelve thousand three hundred forty-five," whereas '1 2 3 4 5' is spoken as "one two three four five."
- The speech engine interprets commas and periods as natural pauses.
- To create longer pauses, combine punctuation (e.g., periods.)
