Speech Authenticity for Voice AI & Video AI
Speech Authenticity helps recruiters evaluate whether a candidate’s spoken response appears natural and unscripted or potentially read from a script.
When enabled, Testlify analyzes the structure and delivery of a candidate’s response and provides an authenticity score along with supporting insights. This can help identify candidates who are speaking naturally versus those who may be heavily relying on prepared scripts.
Important: Speech Authenticity is intended as a review signal and should not be used as an automatic rejection criterion. Recruiters should always review the response, transcript, and overall candidate performance before making hiring decisions.
