Vonage Launches Next-Generation Nexmo Voice API

Vonage, a cloud communications services provider, has announced the launch of the Nexmo Voice API that can be used to integrate enterprise-grade voice capabilities with Web and mobile applications. The newly launched Nexmo Voice API is integrated with Vonage’s carrier-grade network and includes a collection of features such as call recording, text to speech, conferencing, and call control. The company also plans on expanding the features of the API over time. Vonage recently acquired Nexmo and the acquisition has allowed Vonage to enhance and expand its cloud communication products.

The Nexmo Voice API can be used to create Web and mobile applications featuring voice capabilities. The initial release of the Nexmo Voice API includes a number of voice communication capabilities such as:

  • Call Recording – Allows inbound calls to be recorded and stored locally or in the cloud. This feature applies to software-initiated calls and the company plans on adding split-recording and dynamic contextual recording capabilities in the near future.
  • Text-to-Speech – Developers can use this feature to build applications capable of converting textual information into synthesized speech. The platform includes a text-to-speech engine featuring more than 23 languages, different genders, and a variety of accents.
  • Conferencing – Allows developers to add conference call capabilities to applications. Conferencing capabilities can be added using one line of code.
  • Call Control – Makes it possible to control the flow of calls and allows for complex voice use cases. Developers can enable call transfer, hold and playback audio capabilities that can be applied to live calls.

ProgrammableWeb reached out to Tony Jamous, President at Nexmo, a Vonage Company, who provided additional details about the Nexmo Voice API and the Nexmo Communications platform.

"The Nexmo voice API is a next generation API that allows our customers to build complex voice-based applications in the cloud, without having to worry about complex telco infrastructure," Jamous told ProgrammableWeb. "We’ve used this concept to empower developers to make powerful communications in little time, like building a modern and robust voice conferencing service in a few hours. Developers can look forward to increasing levels of abstractions for more complex use cases with the new Nexmo Voice API."

There are a number of companies offering communications platforms and APIs including AT&T, Cisco, Nexmo (a Vonage company), Sinch, TokBox, Twilio, and Vonage. Jamous explained how the Nexmo Voice API differs from some of the other voice APIs on the market. "From a product features standpoint, the Nexmo Voice API functions differently than other voice APIs on the market," says Jamous. "We offer unparalleled control over not only the conversation between two parties, but also granular control of the individual call legs. This allows our customers to create complicated solutions with complete control over the customer experience."

Some of the communications platforms on the market feature both video and voice communications capabilities. At the time of this writing, the Nexmo communications platform does not feature an API for video communications. "Video is an intriguing communications medium and we are constantly listening to our developers and customers on what media and channels they are looking to support," Jamous told ProgrammableWeb. "Right now, we are focused on giving developers robust APIs that give them the flexibility they require to create customized, robust voice communications solutions, backed by a high-quality network for enterprise-grade communication. We will look into bringing these same qualities to a Nexmo video API"

Many of the communications platforms on the market provide APIs that include support for WebRTC and/or ORTC. Regarding WebRTC, Jamous says that "WebRTC is a powerful yet still evolving standard. Vonage Mobile was an early adopter and contributor and in fact, the Vonage Essentials MobileConnect client, used by many of our business customers, makes use of WebRTC. At Nexmo, we are listening to our customers and ensuring that all aspects of an easy-to-use WebRTC API are addressed as we look to adopt the standard into our future roadmap."
