Speech Enhancement & Audio Clarity | Sanas | Sanas
Restore What Telephony Breaks
Traditional noise cancellation removes the background. Sanas Speech Enhancement rebuilds the foreground, restoring what telephony takes away with studio-quality voice from any mic, anywhere.
How we're different
Dimensions of Voice Transformation
Where noise cancellation operates on one axis, Sanas Speech Enhancement rebuilds the voice simultaneously across six distinct dimensions.
Bandwidth Restoration
Expands telephony-grade narrowband audio (300–3.4kHz) to full-spectrum 24kHz. Harmonics and overtones that give voices warmth and texture are restored from zero.
Clarity and Articulation
Consonants are sharpened. Vowels are defined. Sanas treats harmonic and aperiodic components separately, the way the human ear does, delivering speech that is articulate and intelligible end-to-end.
Energy and Presence
Flat, fatigued voices are reconstructed to sound engaged and authoritative. Give your listeners a consistently confident experience.
Hardware Compensation
Cheap headsets, laptop mics, and noisy USB audio adapters all produce degraded input. Sanas elevates the output regardless of the hardware, greatly improving quality for everyone.
Acoustic Correction
Reverb, room resonance, and distance from the microphone all degrade intelligibility. Sanas models these acoustic conditions and corrects for them in real time.
ASR Optimization
Downstream transcription, analytics, and QA tools all perform better with full-fidelity input. Sanas improves Word Error Rate by 5–30% across streaming ASR systems — with no degradation on clean audio.
Hear the Difference
Compare the original audio with Speech Enhancement applied ‑ clearer, richer, and much easier to understand.
How it works
From Narrowband to Ultra-Fidelity
A leap from telephony‑era fidelity to vibrant, high‑fidelity communication. Here's how Speech Enhancement transforms your audio quality without changing your infrastructure:
Audio Analysis
Sanas analyzes incoming audio in real time, identifying noise, reverb, codec artifacts, and frequency limitations that degrade call quality.
Flawless Delivery
Sanas delivers professional-grade audio that captures nuance, presence, and realism. Call participants hear each other clearly, without fatigue or strain.
Noise and Distortion Removal
Background noise, voices, echo, and reverb are eliminated. Clipped audio and packet loss are recovered, delivering clean, professional-sounding speech.
Fidelity Enhancement
Low-fidelity 8 kHz telephony audio is upgraded to 24 kHz ultra-fidelity, restoring the richness and detail of natural speech.
