By 2020, it is estimated that consumers will own 50 billion smart home devices, with many of them integrating audio capture for voice commands. Since speech is most natural interface, the industry has seen explosive growth of voice-activated equipment in smart speakers, smart watches, digital assistants and smart home systems.
For accurate speech recognition, these systems require speech recordings with low noise and distortion. To achieve low noise and distortion, these systems use multi-channel, high performance signal chains for near- and far-field pick-up of voice commands, along with noise reduction algorithms. Moreover, these systems require good distortion performance for effective echo cancellation of the signal driven by the nearby speaker, which is simultaneously delivering audio responses to the user.
In this webinar, you will learn how the latest multi-channel audio ADCs achieve excellent channel-to-channel matching while meeting the low noise and distortion of a multi-channel audio system.
