Cal.ai has introduced AI-driven voice agents to the Cal.com scheduling platform, enabling the automation of phone calls, reminders, confirmations, follow-ups, booking calls, and managing no-shows through natural, human-like interactions. Users can establish triggers based on various events within their existing workflows, such as form submissions, meeting cancellations, or no-shows, and can also assign a dedicated phone number for the AI agent to utilize, with the option to import an existing number. Additionally, users have the ability to craft custom prompts that dictate the tone, personality, and script for each voice interaction. The platform provides seamless integration with Cal.com’s calendar syncing capabilities across services like Google and Outlook, as well as features for scheduling links, team coordination, and directing bookers to the appropriate team member based on their availability and the type of event. Furthermore, the calling system is equipped with analytics that track transcripts, completion rates, booking outcomes, sentiment and tone detection, along with other performance metrics, facilitating the continuous refinement of conversations and enhancement of conversion rates. This comprehensive approach not only streamlines scheduling but also ensures that user interactions are both efficient and engaging.

AethexAI offers a comprehensive voice AI platform tailored for emerging markets, providing end-to-end voice agents that are specifically localized for each market. This innovative solution combines infrastructure, advanced models, and deployment capabilities within a unified environment, utilizing the proprietary Kora 1 models that are trained on authentic conversational speech and human-annotated data from various emerging regions. The Kora 1 Engine is optimized for natural speech interactions, allowing for native tool integration, workflow-aware routing, dedicated infrastructure, and dialect-sensitive communication with turn-taking latency under 500 milliseconds. Organizations can create, launch, and oversee voice agents capable of managing calls, messages, and workflows related to support, sales, onboarding, and collections, all while seamlessly integrating with their existing systems. It facilitates a smooth transition from initial greetings to problem resolution, empowering agents to read and write data, initiate actions, and complete tasks within current systems instead of working in parallel. Additionally, Agent Studio enables users to craft conversation flows, establish guidelines, configure agent personalities, and develop both inbound and outbound agents without requiring any coding expertise. This user-friendly approach ensures that businesses can quickly adapt and enhance their customer interactions.
