# Medical Audio Annotation for Speech AI

Audio clips can be leveraged to train predictive algorithms.

Our annotation platform is tailored specifically to audio clips, with features such as range selection, spectrogram integration, and motion data integration.

## Use cases

### Heart auscultation
Tag the presence of, intensity and time range of heart murmurs, rubs, clicks, S1, S2 and more.

### Lung auscultation
Tag the presence of, intensity and time range of crackles, ronchi, wheezes, stridor, breath sounds and more.

### Artery auscultation
Tag the presence of, intensity and time range of bruits and Korotkoff sounds.

### Abdominal auscultation
Tag the presence of, intensity and time range of bowel sounds, rubs, or vascular bruits.

### Clinical session recording
Tag intonation, emotion, symptoms and medications discussed in clinical interactions.

“The Centaur.ai platform provided labels at a scale that was 10x, or 20x, anything we had done by ourselves. Tremendous scale, tremendous throughput, and high quality labels.”

**Daniel Barbosa**  
Machine Learning Engineer at Eko

"I was very impressed by the Centaur.ai approach to annotation. They provided us with excellent labels on what was a difficult task and noisy data. Centaur.ai understood what the issues were from the beginning, and were able to help steer the project for us."
