Voice Broadcast

Text to speech for urgent customer communications

School closing? Cancelled flight? Package delivered?  TTS can help you call large audiences quickly, with no help required from a third party. Simply create your message with TTS, program your voice and language, and then automate the outbound phone calls.  You can also enable a simple IVR menu so recipients can acknowledge receipt, or automatically deliver alerts to backup contacts.

IVR

Set up and modify your IVRs programmatically with text to speech

TTS can be used to add or update a simple Interactive Voice Response (IVR) script to your existing applications.  No need to wait for Lisa (the admin with the best voice) to get back from vacation so she can record your holiday menu options. With TTS and our voice API, you can quickly create or update menus and prompts, then deploy them as needed.

CAMPAIGN TRACKING

Give your contact center agents an audible heads-up

Skip the screen pops:  with TTS, you can create voice call “whispers” to tell an agent which campaign someone is calling in about before they greet the caller.  When the caller goes through the IVR and makes a selection, automated prompts (using TTS) can be set up for each IVR selection, that are then sent to the agent before the call begins.

TWO-FACTOR AUTHENTICATION

Easily add a layer of security

Verify users with a voice call: instead of an SMS (or in addition to an SMS), you can use TTS to call users with their authentication codes.
