According to xAI, users can define how calls should be handled, connect company knowledge bases and external tools, deploy agents using a phone number or SIP connection, monitor conversations, and choose from synthetic or cloned voices.<\/p>\n
The company noted that most voice AI<\/a> applications combine separate speech recognition<\/a>, language model, and speech synthesis<\/a> components, with each step adding cost, latency, and potential points of failure. Voice Agent Builder instead uses the company\u2019s Grok Voice speech-to-speech<\/a> model through a single interface, which xAI says reduces latency and simplifies deployment.<\/p>\n The platform supports<\/a> multilingual conversations across more than 25 languages and language switching. Pricing starts at USD 0.05 per minute, with additional charges for services including telephony using xAI phone numbers.<\/p>\n The launch follows a series of voice AI announcements from xAI over the past months, beginning with the Grok Voice Agent API introduced<\/a> in December 2025, when xAI opened its in-house voice technology to developers to build voice agents. Since then, the company has expanded its offering with speech-to-text and text-to-speech APIs<\/a>, conversational voice models<\/a>, custom voices<\/a>, and now a visual environment for designing and deploying voice agents.<\/p>\n With this launch, xAI joins a group of companies offering platforms for building and deploying enterprise AI voice agents, including ElevenLabs<\/a>, Synthflow, Retell AI, PolyAI<\/a>, and Vapi.<\/p>\n","protected":false},"excerpt":{"rendered":"According to xAI, users can define how calls should be handled, connect company knowledge bases and external tools,…\n","protected":false},"author":2,"featured_media":97573,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[10],"tags":[17360,7461,2899],"class_list":["post-97572","post","type-post","status-publish","format-standard","has-post-thumbnail","category-xai","tag-speech","tag-voice-cloning","tag-xai"],"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts\/97572","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/comments?post=97572"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts\/97572\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/media\/97573"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/media?parent=97572"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/categories?post=97572"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/tags?post=97572"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
