Explore Sanas’s Human ↔ Human and Human ↔ Machine models and their capabilities. Sanas delivers world-class AI models across two categories: Human ↔ Human and Human ↔ Machine. Sanas currently offers Noise Cancellation and Speech Enhancement capabilities. Accent Translation, Language Translation, and Speech Intelligence coming soon.

## Agentic Speech Enhancement Models

| Model | Use Case | Description | Best For: |
| --- | --- | --- | --- |
| AGENTIC_VI_G_SE | Agentic — Voice Isolation (General) — Human ↔ Machine | Removes all background noise and non-primary voices for complete speaker isolation | Voice agents, IVR, and phone bots that need a single, noise-free speaker isolated from everything else on the line |
| AGENTIC_VI_GT_SE | Agentic — Voice Isolation (Telephony) — Human ↔ Machine | Telephony-optimized variant of VI_G for 8kHz narrowband audio | Telephony-based voice agents and IVR in contact centers running on narrowband (8kHz) call audio |
| AGENTIC_ST_SE | Agentic — Standard — Human ↔ Machine | Removes background noise while keeping all human speech audible | Multi-party calls or meeting/triage agents where overheard background speech still adds useful context |
| VI_G_SE | Voice Isolation (General) — Human ↔ Human | Isolates intended speech by removing background noise and voices | Contact center agents, conferencing, and live/gaming voice chat where listeners need clean, isolated speech |

## Speech Enhancement Models

| Model | Use Case | Description | Best For: |
| --- | --- | --- | --- |
| SE2.1 | SE Standard — Human ↔ Human | Restores and enhances voice quality for telephony audio, outputting 8kHz | High-volume contact centers and IVR systems needing lightweight, low-latency voice cleanup on telephony audio |
| SE2.2 | SE Ultra — Human ↔ Human | Full-fidelity speech enhancement with bandwidth extension to 24kHz | Premium contact centers, conferencing, and telemedicine where full-fidelity audio quality is essential |
| VI_G_SE | Voice Isolation (General) — Human ↔ Human | Isolates intended speech by removing background noise and voices | Contact center agents, conferencing, and live/gaming voice chat where listeners need clean, isolated speech |

## Accent Translation Models

| Model | Use Case | Description | Best For: |
| --- | --- | --- | --- |
| AT5.2 | Accent Translation — Human ↔ Human | Accent Translation modifies global accents in real-time, allowing your teams to be instantly understood while preserving what makes every voice unique. | Contact centers and global teams who need instant, natural-sounding accent translation in meetings and daily calls |

## Language Translation

| API | Use Case | Description | Best For: |
| --- | --- | --- | --- |
| [LT](https://developer.sanas.ai/Docs/Language-Translation/Overview) | Language Translation— Human ↔ Human | Real-time language translation that preserves your speakers’ voices, tone, and intent. | Cross-language customer support and international meetings that need real-time translation while preserving the speaker’s voice and tone |
