proprietary systems, businesses can use API calls to manage voice functionality within their digital products.<\/p>\n\n\n\n<p>When applied to speech, APIs transform voice from a hardware-bound utility into a programmable software layer.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How a voice API works<\/h3>\n\n\n\n<p>Although implementations vary, most systems follow a similar process:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>A user speaks into a device.<\/li>\n\n\n\n<li>The audio is sent to the API.<\/li>\n\n\n\n<li>The API processes the speech (e.g., converts it into
