## Advanced audio algorithms [#advanced-audio-algorithms]

The Convo AI Device Kit employs specialized algorithms to ensure accurate voice recognition and natural conversation flow in challenging environments.

### AI noise reduction [#ai-noise-reduction]

Filters 95% of environmental noise, enabling accurate recognition even in challenging environments like coffee shops and train stations, preventing interaction errors.

### BHVS and voiceprint algorithms [#bhvs-and-voiceprint-algorithms]

* **Background Human Voice Separation (BHVS)**: Filters background voices in multi-person conversation scenarios
* **Voiceprint recognition**: Locks onto the primary speaker in multi-person conversations

### Graceful interruption algorithm [#graceful-interruption-algorithm]

Enables AI to detect user interruption intent in real-time and precisely determine when to speak and when to stop, restoring natural conversation rhythm.

### Weak network resistance [#weak-network-resistance]

Maintains uninterrupted voice interaction even in challenging network conditions like subways and basements, with 80% packet loss resistance capability to maintain conversation continuity.
