Turn Phone Calls into Opportunities

See how our Text-To-Speech service and Voice API Gateway helps businesses like yours to succeed.

Connect when it Matters with Text-To-Speech

It’s harder to ignore a persistently ringing phone than a text or push notification. Using a voice call to deliver a critical alert about a cancelled flight, an early school closing, appointment reminder or even a local emergency alert. Our Text-To-Speech service increases the likelihood of your message being heard.

If your message is critical to get delivered, you can use a simple IVR application to enable the recipient to acknowledge they received your message. Additionally, you can automatically call backup contacts if no acknowledgement is received.

Get Powerful Insights with Voice Polls

Execute automated voice polls via inbound or outbound calls. Ask recipients questions and collect responses via the touch tone keypad. This is great for political campaigns or collecting automated customer feedback.

Verify Customer Identity with a 2FA Voice Call

Two factor authentication (2FA) is the industry standard for keeping your customer accounts secure. 2FA by voice improves your security because your users enter a PIN either by SMS or Voice directly to their handset every time they log in.
