That’s exactly why leading OEM brands have deployed it in millions of devices around the world. ## Bluetooth voice calls sound better than ever ### Superior voice quality in any environment Qualcomm cVc's suite of advanced voice‑processing algorithms operate on both the transmit and receive paths of a call—for superior voice quality, every time. ### Natural, echo-free conversations Background noise and echos are suppressed in real time, giving consumers optimized call clarity on incoming and outgoing calls. Speech is understood and distinctive voices are easy to recognize. ### Consistent quality in challenging RF conditions Even in situations where 5G or Wi-Fi connectivity is slow or erratic, Qualcomm cVc manages to keep call quality consistent. ### Instant clarity right from the start Adaptative noise reduction algorithms in cVc converge very quickly at the start of a call ensuring the very first word is clear. ## More mics, more dynamic sound Our multi-mic noise suppression filters out environmental sounds and background chatter, while adaptive equalizers adjust sound profile dynamically as conditions change around consumers—ideal for calls on the go.1 ![](https://s7d1.scene7.com/is/image/dmqualcommprod/VM-Tech-cVc-04-BenefitImage01?$QC_Responsive$&fmt=png-alpha) ## AI-powered voice and call optimization For more natural two-way conversations, cVc applies acoustic echo cancellation and automatic gain control to keep voice levels consistent, regardless of a consumer’s speaking distance. ![](https://s7d1.scene7.com/is/image/dmqualcommprod/cVc-benefit-2?$QC_Responsive$&fmt=png-alpha) ## Premium call quality even in poor-connectivity environments Howling control, nonlinear processing, packet-loss, and bit-error concealment not only prevent feedback and distortion but also maintain consistent voice quality even when RF connectivity is compromised. ![](https://s7d1.scene7.com/is/image/dmqualcommprod/VM-Tech-cVc-04-BenefitImage03?$QC_Responsive$&fmt=png-alpha) ## Deliver the experiences your customers expect ![](https://s7d1.scene7.com/is/image/dmqualcommprod/VM-Tech-cVc-04-UseCase01?fmt=webp-alpha&qlt=85&wid=1800&fit=fit,1) ### Drama-free Bluetooth call quality, guaranteed An unexpected phone call can be a stressor, but cVc gives consumers the power to answer with confidence from any location. Advanced tech powers clatter-free audio streams and professional‑quality voice clarity everywhere, including noisy sidewalks and busy airports. ![](https://s7d1.scene7.com/is/image/dmqualcommprod/VM-Tech-cVc-04-UseCase02?fmt=webp-alpha&qlt=85&wid=1800&fit=fit,1) ### High-quality comms from the scenic route or highway For consumers who like driving with the windows (or top) down, cVc automatically reduces wind noise and echoes from car speakers. Voice levels stay consistent, so conversation is crisp and clear for both parties—with no need to shout. A satisfying hands‑free experience. ![](https://s7d1.scene7.com/is/image/dmqualcommprod/VM-Tech-cVc-04-UseCase03?fmt=webp-alpha&qlt=85&wid=1800&fit=fit,1) ### Clean audio streams count as win for all parties Background noise like the sound of a TV can be a vibe-killing distraction, especially in a high-stakes competitive gaming environment. cVc resets Bluetooth audio expectations, isolating a consumer's voice from household sounds to keep team comm lines crisp and clear. ![](https://s7d1.scene7.com/is/image/dmqualcommprod/VM-Tech-cVc-04-UseCase04?fmt=webp-alpha&qlt=85&wid=1800&fit=fit,1) ### Hear and be heard even in extreme noise AI voice processing running on Qualcomm's powerful eNPU neural accelerator, ensures that voice quality is retained even in extreme noise where face to face conversation would be impossible. ## Platforms for every product tier Snapdragon Sound Platforms deliver the right mix of performance, features, and efficiency for audio products in any market segment.
