Decision models for voice AI
The bar is human. Hume diagnoses system breaks and feeds failures into improvement.
A sample telehealth call plays while three questions about it are answered for every five seconds of audio.
Why audio needs a decision model
Voice AI considers tone, pauses, and sounds. Developers set Q&A; the audio decision model gives probabilities for quick audio judgments.
Different questions. The same audio.
Ask objective, subjective or perceptual questions about speech and sound. Select a tab to explore examples.
One speaker
Two speakers
Three or more speakers
Find the audio worth acting on
Ask more of the same audio
Apply several questions to the same recordings, from naturalness and clarity to empathy and timing.
Designed for fast evaluation
Repeat evaluations across your collection as your model or criteria change.
Pinpoint cases for your next step
Find candidate examples for training, isolate evaluation failures, and surface cases for escalation review.

Questions
about the model
It’s Hume’s audio-native decision model. Developers submit audio, a question and possible answers; it returns a probability for each answer. It helps teams evaluate speech and sound, assess how a voice comes across to listeners, and inform decisions in voice applications.
