Anything slower creates a noticeable gap \u2014 that awkward pause that immediately signals &#8216;I&#8217;m talking to a machine.&#8217; This isn&#8217;t just a user experience issue; it&#8217;s a fundamental barrier to adoption.<\/p>\n<p>Most voice AI systems operate at 800ms-3000ms latency. Users notice. Satisfaction drops. Call abandonment rises. The promise of AI automation falls apart.<\/p>\n<h2>How AeVox Achieves Sub-400ms<\/h2>\n<p>AeVox&#8217;s Continuous Parallel Architecture doesn&#8217;t wait for one process to finish before starting the next. Instead, it runs acoustic analysis, semantic understanding, and response generation simultaneously through dual parallel streams.<\/p>\n<p>The Acoustic Router handles initial routing in under 65 milliseconds. While the deeper semantic engine processes context, the fast path has already begun generating a response. The result: sub-400ms total latency that crosses the psychological indistinguishability barrier.<\/p>\n<h2>The Business Impact of Speed<\/h2>\n<p>Our enterprise customers report 60% reduction in call abandonment rates and 45% improvement in customer satisfaction scores after deploying AeVox. When AI feels human, customers engage naturally \u2014 and businesses see real ROI.<\/p>\n<p>At $0.30 per minute, AeVox delivers enterprise-grade voice AI at a fraction of the cost of human agents.<\/p>\n<p><a href='https:\/\/aevox.ai\/demo'>Experience the Speed \u2192<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The 400ms latency barrier is where AI becomes indistinguishable from human.
