The Vonage Voice API is the easiest way to build high-quality voice applications in the Cloud. With the Voice API, you can build apps that scale with the web technologies that you are already using, control the flow of inbound and outbound calls in JSON with Nexmo Call Control Objects (NCCO), record and store inbound or outbound calls, create conference calls, and send text-to-speech messages in 23 languages with different genders and accents.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
