What your voice reveals – Vocal Expression AI with audEERING’s devAIce®

audEERING’s latest white paper: From human behavior to cutting-edge Voice AI technology

Your voice is more than just a tool for communication – it’s a reflection of your emotions, energy, and even health. With devAIce® v3.14.0, audEERING® introduces the latest advancements in AI-powered voice analysis, capable of detecting mental states, estimating age, and identifying vocal health indicators.

Expression detection: Giving machines empathy

Emotions aren’t just expressed in words – they’re in HOW we say them. devAIce® analyzes prosodic features like loudness, pitch, speech rate, and intonation to capture emotional cues in real-time.

It operates with two advanced models:

Dimensional analysis (measuring arousal, dominance, and valence on continuous scales)
Categorical classification (detecting core emotions like anger, happiness, sadness, and neutrality)

This dual approach ensures both nuanced and precise expression recognition, enhancing human-machine interactions.

Estimating age and gender – With accuracy and fairness

Trained on millions of speech samples, devAIce® can estimate a speaker’s (biological) gender and age. To minimize bias, audEERING trains its models on a diverse dataset spanning multiple languages, accents, and voice types, ensuring a fair and representative AI.

How the AI learns to listen

devAIce® leverages Transformer-based models trained on commercial, public, and synthetic datasets. It also integrates multimodal learning, combining voice with text and visual inputs to enhance emotional understanding.

Tested for real-world performance

Our models undergo rigorous testing to ensure:

✅ Accuracy – Measured with industry standards like CCC and UAR

✅ Robustness – Performs even in noisy environments

✅ Fairness – Evaluated across gender, pitch, language, and accents

✅ Efficiency – Optimized for low latency and minimal memory usage

Real-world applications: From call centers to Conversational AI

audEERING’s voice analysis technology is already transforming industries:

📞 Call Centers – Real-time tracking of customer sentiment and agent performance

🏥 Healthcare – Voice-based indicators for stress, cognitive decline, and diseases like multiple sclerosis

📊 Market Research – Detecting engagement, boredom, or interest from vocal patterns

🤖 Conversational AI – Making chatbots and voice assistants sound more natural and empathetic

And a recent industry study even found that over 70% of game developers see empathic AI as a game-changer for immersive storytelling.
