The Science Behind VoxEQ

VoxEQ’s Verify solution listens for life. Our advanced, multi-layered fraud defense is grounded in the biological signals of the human voice—traits that can’t be mimicked by synthetic audio or manipulated by bad actors. From the first second of a call, Verify begins evaluating the authenticity of the speaker, regardless of whether or not they’re enrolled. This approach ensures that every caller is checked against what makes us uniquely human.

1. Known Fraudster Detection VoxEQ flags callers whose voices have previously failed identity verification—helping organizations stop repeat attackers in their tracks. These voiceprints are enriched with biosignal profiles (like age and vocal dynamics), providing a powerful early-warning system.

2. Caller Attributes Match Our system detects human vocal traits like estimated age and birth sex by analyzing involuntary bio-signals such as glottal flow, vocal fold oscillation, and harmonic frequencies. Why it works: Synthetic voices sound convincing—but they don’t breathe, vibrate, or age like real human beings. This layer ensures that the speaker's biological reality aligns with account records—even without opt-in—and flags anomalies in real time.

3. Voiceprint Match For callers who’ve enrolled, we validate identity using high-resolution biometric voiceprints. During enrollment, Verify checks new samples against biosignals and historical voice data, catching impostors who attempt to sneak in first. Voiceprints aren’t just matched—they’re contextualized with human bio-patterns to ensure authenticity at a physiological level.

At VoxEQ, compliance isn’t an afterthought—it’s the foundation of our solutions. VoxEQ does not receive or process any personally identifiable information and does not store audio. Our innovations are designed from day one to meet rigorous regulatory standards while empowering your compliance team as a strategic partner. This commitment to responsibility has been a cornerstone of our shared success.

Every organization has unique risk tolerances and business scenarios. VoxEQ allows you to fully customize thresholds based on specific actions—for example, allowing marginal results for low-risk inquiries but requiring high-confidence matches for sensitive operations like moving money. Customers can set as many thresholds as needed to precisely match their operational requirements.

Additionally, VoxEQ Verify enables institutions to set and adjust their acceptable False Positive Rate (FPR)—measured as false positives per thousand—in real time. This flexibility allows fraud systems to dynamically become stricter or more lenient, adapting instantly to changing risk levels, seasonal trends, or operational demands. When unusual activity or increased fraud threats are detected, you can quickly adjust your settings to enhance caution, confident that the system will maintain an optimal balance between security and efficiency. By clearly defining acceptable false positive budgets, VoxEQ Verify ensures the cost of blocking legitimate users remains lower than the risk of missed fraud, maximizing both efficiency and ROI.

VoxEQ also provides built-in default thresholds categorizing interactions as valid, marginal, or invalid—where “invalid” indicates it’s highly unlikely the caller is legitimate—offering a robust starting point for most use cases

VoxEQ’s solution is rigorously trained on both clean and challenging audio samples, delivering reliable performance in real-world conditions. In exceptionally noisy or distorted scenarios, the system transparently indicates when results are invalid to ensure you always have clear, actionable insights.
