Voice AI Testing
Evaluation and compliance testing for phone screening AI, voice analysis, and speech-based candidate assessment.
Important: Emotion Recognition is Now Prohibited
As of February 2025, the EU AI Act prohibits AI emotion recognition in workplace contexts, including recruitment. Voice AI systems that analyze emotional states, sentiment, or personality from voice are likely non-compliant.
The Challenge
Voice AI promises to revolutionize phone screening—conducting initial interviews at scale, assessing communication skills, and identifying promising candidates. But these systems carry hidden risks that can create serious legal exposure.
Beyond the now-prohibited emotion recognition, voice AI systems often discriminate against non-native speakers, candidates with accents, and those with speech differences. These biases can systematically exclude qualified candidates and expose your organization to discrimination claims.
We test voice AI systems to identify compliance issues and hidden biases before they become problems.
What Can Go Wrong
Common failure modes we test for in voice-based recruitment AI
Accent Discrimination
Voice AI often performs poorly on non-native speakers, regional accents, and non-standard speech patterns.
Emotion Recognition Ban
EU AI Act prohibits emotion recognition in workplace contexts—many voice screening tools violate this.
Speech Impediment Bias
Candidates with stutters, dysfluencies, or neurodivergent speech patterns may be unfairly penalized.
Background Noise Sensitivity
Candidates in less affluent environments may score lower due to background noise interference.
Language Model Bias
Speech-to-text models may misinterpret cultural expressions or domain-specific terminology.
Inconsistent Scoring
The same response may receive different scores depending on voice characteristics unrelated to content.
