Key uses for Cartesia voice AI in recruiting

Make applying easier

Allow interested jobseekers to submit applications via phone instead of filling out tedious forms, avoiding drop-off and ensuring complete information.

Screen candidates

Offload early-stage applicant interviews, giving them more flexible scheduling—and recruiters more time to focus on qualified and engaged applicants.

Provide status updates

Move updates, one of the most time-consuming parts of recruiting process, to an automated phone system, and let candidates get updates 24/7.

Unbiased assessment

By removing humans from the interviewer's seat, you'll also help remove unconscious biases. Candidates will have all the comfort of talking to a human-like voice, without positive or negative leanings on the part of human interviewers affecting hiring managers' judgement.

Unrushed interviewing

No more "Sorry, I have to end this call on time so I can go to my next meeting." Interviews can be scheduled to go as long as you need to properly assess applicants and answer their questions—instead of squeezing everything into the standard half hour.

Flexible scheduling

Give candidates the freedom to choose the interview time that works best for them, regardless of recruiters' calendars or time zones. With an AI recruiter interviewing, calls can be scheduled for any time—early morning, late night, even weekends.

Elise AI

We didn't switch to Sonic 3.5 because it was incrementally better, we switched because nothing else came close… we've seen a 2.9% lift in our conversion and a 12.2% increase in customer engagement.

ServiceNow

Cartesia's state-space models bring enterprise-grade speed and quality to our AI Voice Agents… making it possible for businesses to deploy secure, scalable voice agents that can understand, act, and adapt in real time.

Sierra

Cartesia Sonic 3.5 has become one of the top-performing models for us by combining low latency with natural pacing… helping us deliver strong voice quality across a growing set of languages where other models often fall short.

Callers

Sonic 3.5 has been a meaningful upgrade for Callers… latency and naturalness directly impact conversational flow and user success, and the new model noticeably improves both. We've seen more human interactions — especially in high-volume customer conversations where every millisecond and every turn matters.

Take2 AI

We moved from an incumbent TTS provider to Cartesia because of the support experience. After repeated roadblocks with our previous provider, the difference with Cartesia has been transformative — responsive, technical, and genuinely invested in our success.
