Why Teams Choose Modulate Over Resemble AI

Deepfake Detection vs. Conversation Intelligence

Resemble AI determines if audio is AI-generated or not. Modulate provides the deeper insight teams need to understand conversations, like speaker intent and risk signals such as tone, pacing, interruptions, and call dynamics. These are valuable signals that can tell the difference between fraudulent deepfakes and someone just using a voice assistant.

Built for Continuous Monitoring

Resemble AI is designed and priced under the assumption that a few seconds of a call should be tested for synthetic voice - and if none is found, the call is safe. Modulate’s models instead are built to continuously monitor the entire call cost-effectively, ensuring that any use of deepfakes at any point is caught.

Detect Fraud, Not Just Synthetic Audio

AI-generated voices are only one tool in a social engineer’s toolbox. Where Resemble AI only detects deepfakes (audio, image, video), Modulate detects threats through the analysis of conversational behavior to identify and flag risky signals such as urgency, pressure, manipulation, and inconsistencies.

Transparent Benchmarks and Real-World Performance

Modulate publicly releases results on our leaderboards for transparency and easy team comparisons. Our deepfake detection models have achieved the highest publicly reported accuracy on 12 industry standard synthetic voice detection datasets, with less than half the error rate of Resemble’s top model. And Modulate’s Ensemble Listening Model (ELM) is built using real world conversational audio (not cleaned or processed audio samples) for better accuracy on calls with any kind of background noise.

Here’s What This
Means for You

Visibility into every conversation, not just synthetic audio.

You don’t just want to know if someone used synthetic audio on a call. You want to know what happened. Layer those insights on top of detection. Modulate offers tone, intent, and behavior analytics in real time, rather than a binary “yes or no” to whether something was AI generated. 

Go beyond deepfake detection to identify fraud.

Tools like Resemble AI are great at identifying synthetic voices, but that’s just a single threat vector. Some real-world attacks today are perpetrated with regular human voices using social engineering. Modulate detects those behaviors and patterns in real time, from urgency to manipulation to cognitive errors. 

Real-time detection and intelligence to act on during an active call.

Modulate was built specifically for use cases within live voice applications. That means risks, alerts, and coaching opportunities are surfaced as they happen during a call. If you’ll be using this technology on active customer interactions or within contact centers, that’s key.

Technology built for operations use cases.

Resemble AI specializes in synthetic media processing and voice generation. Modulate helps you operate real-world conversations at scale. Contact center monitoring, fraud prevention, compliance, and AI agent coaching are just a few of the use cases for Modulate.

Modulate makes our benchmark results on public datasets available to everyone.

This means you can look at how our model performs compared to the industry on standardized datasets. This is great if you need to provide proof to stakeholders on tooling decisions, or require accuracy percentages for regulated industries.

Deploy quickly without reworking your voice stack.

Both Modulate and Resemble AI offer APIs, but Modulate works out of the box with voice and telephony solutions. You can analyze calls, trigger actions, and scale up usage without changing your existing tech stack. 

You don’t have to choose between detection and intelligence.

Both Modulate and Resemble AI can detect AI-generated audio. Where Modulate differs is after that detection occurs. Modulate provides teams with continuous intelligence about fraud, CX, and operations, while Resemble AI focuses on voice generation and authentication.

Build Voice Systems That Understand Conversations

Voice contains far more intelligence than authenticity signals. Voice also conveys intent, risk, and opportunities to take action in real time. Platforms that only deliver synthetic audio detection can tell you whether a voice is real, but not what’s really going on in a conversation. 

Modulate turns voice data into actionable intelligence. Our deepfake detection and conversation analysis technology arm teams with the ability to monitor calls for fraud, compliance, and sentiment as they’re happening, not after the call concludes. Get real-time responses, make smarter decisions, and gain visibility across every customer interaction. 

Features Built for Real-World Voice Interactions

Live voice interactions are noisy and unpredictable. Calls have background noise, interruptions, people talking over each other, and changing context. Voice intelligence needs to operate within that chaos to deliver real-time insights. 

Monitor Conversations in Real Time

Make sense of live calls as they’re happening. Identify fraud risks, compliance violations and customer sentiment during the call and take action now rather than after.

Deepfake Detection with Context

Detect AI voices in seconds but also analyze how that synthetic voice interacts during the call. Distinguish between false positives and true fraud by understanding the conversation around the AI voice.

Detect Fraud at the Conversation Level

Pinpoint social engineering and other manipulative tactics by understanding tone, pace, pauses and inconsistencies. Detect threats that use more than just fake audio.

Detect Intent as Well as Speech Artifacts

Go beyond deepfake detection by understanding not just what was said, but how it was said and how it will impact the interaction.

Trigger Workflow Actions

Use real-time alerts and insights to trigger action directly from a call. Set up alerts, escalations or workflows based on live call analysis.

Seamless Speech Intelligence Integration

Integrate transcription, conversation intelligence and fraud detection into your existing workflows quickly and easily. No need to make complex telecom changes or enroll speakers.

Enterprise Capabilities and Flexible Deployment

All of our products come with robust security, encryption, and governance features. Transcribe and analyze as many calls as you need without losing performance.

What You Gain with Modulate

Faster identification of synthetic and suspicious callers. While our deepfake detection models will find AI voices in seconds, Modulate also scores conversational behavior so you can triage and take action sooner.

Gain visibility into every conversation. Other tools require you to submit clips or suspected deepfake audio. Modulate analyzes your entire conversations so you can discover fraud, compliance, and CX risks at scale.

Protect against more than synthetic voices. Voice generation and authenticity products can identify AI-generated audio. Modulate’s analysis of tone, intent and conversational dynamics shows you what’s really going on during the call.

Detect caller risk signals for real-world social engineering. Fraud isn’t always synthetic audio. Real world risk can come from urgency, manipulation, inconsistency and more. Modulate helps you detect those signals so your agents can recognize dangerous calls that otherwise look normal.

Maintain high accuracy on low-quality call audio. Calls come with background noise, interruptions, connectivity drops, and more. Since Modulate is trained with real-world conversational audio, low-quality audio doesn’t impact accuracy.

Simple pricing as you scale. Usage-based pricing means you can analyze large volumes of calls without unexpected costs or difficult implementation. 

Deepfake Detection + Voice Intelligence You Can Trust

Identifying synthetic voices is only part of the battle. Security, sales, and CX teams need visibility into every conversation: fraud cues, customer intent, operational risk. Context matters.

That’s where Modulate’s deepfake detection and conversation intelligence solutions come together. Built on one platform designed for real-world voice interactions, you can monitor calls live as they’re happening, identify social engineering and malicious behavior, and easily surface high-risk conversations with API integrations that fit into your workflows.
