Introducing HANCE 26: Our Latest Speech Processing Models

HANCE 26: The Audio Algorithm Designed for Real-World Complexity

Live audio is situational and imperfect. It  comes with background noise, room reverb, overlapping sounds, and unpredictable conditions that controlled environments don't capture.

Our latest and most capable model yet, HANCE 26, is built to handle that complexity. Here's what that means for your audio:

• Removes more noise and reverb, with even fewer artifacts.
• Improves speech intelligibility, also in challenging conditions.
• Handle tonal languages and non-English phonetics with improved accuracy.

What changed from HANCE 3.0

To build a model that works across real-world conditions, you need scale. HANCE 26 uses significantly more training data than its predecessor, allowing the model to generalize across more audio situations than ever before.

HANCE 26 includes:

• Rebuilt neural network architecture
• Expanded training data
• Refined signal processing

Rebuilt neural network architecture

We redesigned our neural network specifically for audio processing. The previous architecture found challenges  with sharp transitions and sustained sounds: long vowels, drawn-out musical notes, continuous background tones. These would often be processed inconsistently or could introduce artifacts. The new architecture handles transitions and extended audio events smoothly and predictably, and manages these scenarios more consistently overall..

Expanded training data

Models only generalize as well as their training data allows. HANCE 26 is trained on significantly more high quality data than HANCE 3.0, with increased voice variations and augmentation applied across thousands of additional hours of diverse audio. This includes different microphones, acoustic environments, recording conditions, and sound sources

Refined signal processing

We went back to fundamentals and rebuilt how we handle high-frequency content. The previous approach occasionally introduced artifacts in the upper frequency range. The new processing significantly reduces those artifacts without compromising the rest of the signal.
