Your customers are ready for AI
The Vonage Global Customer Engagement Report 2024 showed that 80% of global consumers have used AI tools recently, and the majority are happy to do so — as long as they get the results they want.
Voice API is the ideal fix to some of the most common pain points:
63% are frustrated with long wait times to speak to someone. Our responsive Voice API, combined with Vonage AI Studio's proprietary NLU engine, means customers can get the answers they need without waiting on hold.
59% don’t like businesses with no way to contact them via voice/phone. Vonage Voice API can provide 24/7 service, and if the caller does need to speak to a live agent, the combination of sentiment analysis and NLU means they can be routed through or have a call back scheduled as needed.
54% can’t access customer service in their preferred language. With support for 120 languages, from Afrikaans to Zulu, our Vonage Voice API can ensure there’s always a way to communicate — even if you don’t have any staff that speak the language.
Extend, customize, and differentiate your customer experiences with Voice Call API
Our Voice API enables an interconnected suite of solutions that extends IP Voice and PSTN calling experiences on a global scale and in multiple languages.
Deliver seamless communications with Programmable SIP. Bring Vonage Voice API functionality, such as multichannel recording, IVR, Text to Speech, WebSocket connectivity for AI integrations, and the power of contextual conversations to your platform.
