What is a Voice API?

Voice APIs allow businesses to integrate and automate inbound and outbound voice calling functionalities into applications, software, and networks. These APIs use Hypertext Transfer Protocol Secure (HTTPS) to translate instructions from developers' code into commands carried out on the phone network. Key features of voice call APIs include call control, text-to-speech and speech-to-text, media playback, conferencing, recording, real-time transcription, answering machine detection, and media streaming. Voice calling APIs can be used in various industries such as gig economy, human resources, healthcare, customer service, and more. Programmable voice APIs offer several advantages over legacy solutions like SIP telephony, including reduced infrastructure requirements, ease of configuration, flexibility, and cost-effectiveness. When choosing a voice API provider, consider factors such as call quality, developer resources, and global coverage.
