MessageBird's Voice Messaging API enables you to transform text messages into voice messages to any country. Each voice message is identified by a unique random ID that can be used to check the status of the voice message. You can select from 26 languages and different attributes such as male or female voice, speaking rate, repeat, schedule, and more.
The Voice Messaging API uses HTTP verbs and a RESTful endpoint structure with an access key that is used as the API Authorization framework. Request and response payloads are formatted as JSON—although we provide a GET alternative for requests—using UTF-8 encoding and URL encoded values.
