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.
