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](/portalv3/docs/product-updates). For detailed benchmarking methodology and performance data, see [Sanas science blogs](https://www.sanas.ai/science). --- #### 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 | **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 | **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. --- ### Support **Need help?** Get in touch with our [Support Team](mailto:support@sanas.ai) for assistance.
