Introduction
The following document lists Sanas' Speech Enhancement ( SE) model releases. Versions are listed newest-first. Each entry summarizes what changed and who it affects.
Speech Enhancement builds on all Noise Cancellation capabilities and adds high-fidelity audio processing at a higher sampling rate, producing richer, more natural-sounding output. Like NC, SE uses independently trained AI models for each audio direction— outbound (agent-side) and inbound (customer-side).
For desktop application releases that bundle these models, see Product updates. For detailed benchmarking methodology and performance data, see Sanas science blogs.
SE2.1
| Field | Detail |
| Model version | 2.1 |
| Speech capability | Speech Enhancement |
| Audio direction | Outbound and Inbound |
| Sampling rate | 8kHz |
| Available modes | - (Outbound) Voice Isolation - Near field and Far field - (Inbound) Standard with ringtone passthrough |
| Release status | GA |
What changed
- Eliminates reverbs and room acoustics from speech
- Restores audio packet loss due to a poor network connection
- Corrects audio degradation via the codec compression
- Improved audio fidelity on the old telephony systems (8kHz)
- Improvements in the background environmental noises and distant speech removal
- Overall enhancements in speech clarity, articulation, energy, and vocal presence.
SE1.0.1 (Outbound)
| Field | Detail |
| Model version | 1.0.1 |
| Speech capability | Speech Enhancement |
| Audio direction | Outbound (Sanas app user’s-side) |
| Sampling rate | 24kHz |
| Release status | GA |
What changed
- Includes all outbound Noise Cancellation capabilities, background noise suppression up to 80–90 dBA, background speech cancellation, and support for 8,000+ noise profiles.
- High-fidelity 24kHz audio output delivers richer, more natural-sounding speech compared to the 8kHz telephony-grade output of NC models.
SE1.0.1 (Inbound)
| Field | Detail |
| Model version | 1.0.1 |
| Speech capability | Speech Enhancement |
| Audio direction | Inbound (Call recipient’s-side) |
| Sampling rate | 24kHz |
| Release status | GA |
What changed
- Includes all inbound Noise Cancellation capabilities — far-field speech preservation, handling of unpredictable ambient environments, and support for variable-quality audio sources.
- High-fidelity 24kHz audio output enhances the clarity and naturalness of the customer's voice beyond what NC inbound models provide.
